2007 S3 (BHZ) Intermittent Start Up Issue

[HHS3]

Hello,

I got my S3 in May 2015 and what a great bit of kit it is, it's an absolute beast and the Quattro system makes it handle like a dream.

I've only had two issues with it since I picked it up of which one remains whereby once the engine has fully warmed up, if you try turning the engine on again, it takes a few seconds to crank over before starting. If the engine is cold then there's no issues whatsoever and if I drive to the shops nearby so the engine is only mildly warm then again there's no issues. Also as soon as it's started, it runs smoothly with no problems.

I've had a look online and it's either down to the starter motor (incorrect crank speed), battery (incorrect crank speed), camshaft sensor or crankshaft sensor. The most common reason was the starter motor and a couple other people on this forum found that they had replaced a couple other bits but only when the starter motor was replaced, meaning the correct crank speed was in place, did the hot start up issue go away permanently.

I'm getting a stage 1 Revo remap, Revo race intake system (camcoat) & Revo panel filter done next month so I want my car to be sorted for then, just checking what people's thoughts are regarding the starter motor? As the threads I checked were a couple years old so any fresh information would be appreciated.

• I never boot it from cold, always let the engine reach 90 degrees before ragging
• At the end of journeys I also give it a couple of minutes towards the end without tearing
• Full service done in November 2015
• No fault codes
• Had coolant temperature sensor changed
• PCV valve changed (to fix idling issue)
• Battery checked in 2014 service, it was fine

Thanks.

Anyone?

I also forgot to mention that whenever I get in my car, I turn the key in the ignition twice and wait for all of the lights to go off on the dashboard before turning the engine on.

My car went in for an MOT on Friday and I got them to replace the Crankshaft Sensor. Although I have noticed a slight improvement on hot start ups, there's still an issue.

I drove normally to a mates house 5 minutes away, picked him up and let the engine warm up to 90 degrees, then gave it an absolute caning for about 30 minutes, parked up at another mates house, let it cool down for a couple of minutes and turned the engine off. Two hours later I got back in, it started up fine, drove normally to the shops 20 minutes away. Got back in a couple of minutes later and it started up fine again, had a little bit of a tear for 10 minutes back to mates house and parked up for an hour. Went to drive home and it took 3-4 seconds to crank over before finally starting, even though this used to happen a lot more often, it still frustrates me that it is still having trouble!

Starter motors aren't cheap so I'm going to get the Camshaft Sensor done next to see if this fixes the problem. I just find it odd that there's only been a handful of other S3 8P1 owners to have this issue.. My cars now done 53K, I picked it up on 48K and the previous owners looked after it immaculately as there's no visual damage and a full Audi Service history.

Any ideas or suggestions would be most appreciated as my S3 is my pride and joy of which this is really bugging me!

hello i have the same problem with my audi a3 1.9tfi (BXE) and was just wondering if you have sonce changed the camshaft sensor as im looking to do this next, also does your car smoke a lot on start up like clouds of white smoke? mine does this the first 5 minutes of starting up but it doesnt always do it only now and then, thanks in advance

Hi mate, I'm booking my car in next Friday to get this done along with another couple of bits (prior to the remap!) so I will let you know the outcome. @eLeCtRaSh said on your thread that he was getting the Camshaft Sensor done yesterday, so hopefully he'll let us know how that went.

I don't get any white smoke but I have a petrol engine not diesel, so this may have something to do with it. I did a lot of searching on here and Google of which there was quite a few A3 diesel owners with a hot start up issue but only found a handful of S3 owners. On the petrol engines it got resolved by replacing either the Coolant Temperature Sensor, Crankshaft Sensor, Camshaft Sensor or Starter Motor - not sure if the same applies to diesel engines but replacing fairly cheap parts like sensors first is a good place to start.

okay mate thanks for the reply! I have replaced the temperature sensor recently but no luck.

I think my turbo has gone now though hence the white smoke I have just posted a thread but funnily enough that has made the hot start problem go away :S !

Hmm how strange that the hot start up problem has now gone away, sorry to hear about your turbo though that is long!

 

[HHS3]

I had the Camshaft Sensor changed on Friday, I've been for a couple of rags since and done a few stop starts of which so far so good! It's still too early to tell if the problem has gone away permanently but having both the Crankshaft and Camshaft sensors changed have definitely made an improvement at least.

I'm going in for Stage 1 Revo remap and Revo race CAI tomorrow which will definitely make me boot the car more than I usually would! This will be a good test to see if the hot start up issue has been permanently fixed.

 

[Mujnu]

When you go for the stage 1 tell them to give you the hot start fix patch, that may resolve the issue

Thanks for the information, can you expand on it at all please? As I've never heard of it before.

I don't know if it's the same on petrol cars but with diesels when the engine is hot it doesn't use fuel to start the engine but on a cold engine it does, so the hot start patch I think tells the engine spray fuel regardless of temp - something along those lines lol. Read up on it loads of information on this forum regarding it, but as I said don't know if it applies to petrol cars too.

Spot on cheers mate.

I've just had a search on here but couldn't find anything about a hot start patch, I'll mention it to Gavin at VAS Motion anyway and see what he thinks.

The stage 1 Revo remap has been on for nearly a week now and I have yet to experience any issues on hot start ups which is great! It's fair to say that I've been giving it some recently (the Revo CAI sounds mint!) so some thorough testing has been done on this.

I'll be sure to update this thread if I encounter any further problems but it looks like it was the Camshaft Sensor that was the issue in my case, although changing the Crankshaft Sensor did make a difference as well. I'm grateful it was only a £20 fix as I wasn't looking forward to the last resort of spending £400 on a new starter motor.

 

[HHS3]

It's been a couple of months now since I've had the crankshaft sensor, camshaft sensor and remap done of which I am still getting the odd start up issue unfortunately..

I used to think it was just when the engine was warm however there's been a couple of times it's done it from cold as well. I went away on holiday for a week and tried to turn the car on when I got back of which it cranked over for 5 seconds and failed, so I gave it a few seconds and tried again, 3 or so seconds later it finally turned on.

Just to reiterate that there hasn't been any fault codes after multiple scans at my brothers Toyota garage, as well as the above, the coolant temperature sensor and PCV have both been replaced. The battery appears to be in fine condition as there's no problems with electrics either etc.

That just leaves the starter motor, unless anyone else has any other ideas? Giving there's no error codes then I can't see what else it would be though to be honest and I know it's a common problem on the diesel engines. I take it Bosch make the best starter motors, so I'm looking at around £140?

Hi there my sisters a3 has a hot start problem i replaced the battery but think that it must just be a lazy starter but there are multiple choices and im yet to get the part number, i would reccomend you get the glow plugs checked if you're having cold start problems and id see its most likely to be the starter causing your hot start let. Keep us updated

 

[chaz1702]

Just to add, i find andrew page and apd very competitive on parts but if you are willing to wait i would highly reccomend bestpartstore.co.uk just ordered a rad fan off of them they were very cheap and high quality (sell the likes of lucas, bosch and hella) but only problem i had was they said it was 'ready to be dispatch in 24 hours' but it took them 3 days to dispatch they are based in germany even though they use a .co.uk domain, good luck

 

[Bazzle]

I had a similar intermittent issue.
Batt seemed ok.
Anyway changed batt out, no problems for last 4 months.

Ok cool, thanks for the information mate. Will do and likewise if you have any updates.

Interesting to know ta. I would rather it be the starter motor to be honest as I had a remap done a couple months ago and don't want to have to spend an hour and a half driving just to put it back on again if a new battery is required!

I picked my S3 up in May 2015 and it's last service was in October 2014. So in August 2015 I asked my bro's work to do the cheapest service they could do, however I only found a couple months ago that they didn't technically service it but did a vehicle inspection test instead which covers similar things but not everything. So I'm going to get it booked in for a proper service and get the spark plugs & coil pack changed etc. then ask them to check the battery and starter motor whilst they're there.

 

[HHS3]

@chaz1702 I had a service done a couple of weeks ago and got all of the spark plugs, coil packs and starter motor replaced, however the problem still prevails!

It seems to be happening more so from cold now and the battery is all that's left to change. Makes sense as someone made the valid point it only used to happen when cold if left for a few days. The battery has never been replaced to my knowledge and so would mean that it's 9 years old, so time for a change anyway. The previous owner only used it at weekends and not every weekend in the last few months of ownership so it seems very plausible now. If it is the battery (which I hope it is now), then I've only wasted £450 on a starter motor, coil packs, spark plugs, crankshaft & camshaft sensor and that's without labour Suppose new parts don't hurt but not when I don't have the money!

I left the battery till last as I have a Revo stage 1 remap of which their website states that if the battery gets disconnected, then the map will revert back to stock Revo settings B1 T0 F0. I would have to do and hour & a half round trip to get it put back on or find someone local with an SPS.

I mentioned this to my girlfriends dad of whom said when his VW Passat's battery needed replacing, the garage next to his work had some equipment which you could connect up to keep the power live which meant he didn't lose his radio settings etc. Would this work with the remap as well?

 

[HHS3]

The intermittent start-up issue still persists whether it's hot or cold.

I had the battery replaced over a month ago with a Varta Silver Car Battery E44 77Ah (577400078), a day or so after there was a slow start-up but then it was fine for over three weeks. However on Tuesday when it was hot, I had two slow start-ups within an hour of each other but then absolutely fine half hour later and all of yesterday. This morning was fairly cool, engine was cold and again had another difficult start-up..

I have no idea what it could be now as I've replaced the crankshaft sensor, camshaft sensor, spark plugs & coil packs, starter motor and battery, as well as the the coolant temperature sensor due to a different issue, but to no luck.

Just to reiterate:

• I let the dash do a full sweep before starting the car up
• I never boot it from cold, always let the oil reach 90 degrees before ragging
• The last minute or two of driving is always slow, if I've been tearing it then I'll also idle for 30 seconds after the final slow drive before turning the car off

I now know that I've got a problem with my intake manifold and motor which is leading to a drop in pressure at times, I'm getting Storm Developments to do some further diagnostics on this to confirm.

Would a drop in manifold pressure affect start-ups?

Could it be the clutch? I'm not sure if I'm correct in saying this but my car (8P 1.9tdi) started doing this and I think my clutch / dmf may be to blame.

I'm not mechanically knowledgeable at all, therefore would you mind briefly explaining to me how the clutch could affect start-ups please? My stock clutch is on 58K now (I picked it up on 48K), I went stage 1 in April of which there was no change and again stage 2 last week with no change. It'll be on it's way out next year so I'm getting ready for a Spec 2+ clutch & steel SMF in preparation for stage 2+.

I'm just speaking from personal experience lol I'm on R-Tech stage 1 and I had a starting issue which was due to the clutch/dmf, I had it changed under warranty and then the issue went away until my map started eating away at the clutch and now the issue is somewhat back, for that reason I'm asking if there could be a relation?

I think I read it somewhere too but it was a long time ago so can't remember exactly where and how true it is I don't know, as I'm in the same boat as you when it comes to mechanical knowledge lol

Ok cool cheers for the information, it sounds like it could be related to be fair then, I'll get Storm to have a look whilst they're there. My stock clutch currently only slips if I redline it in 1st and dump the clutch, if it is this then I presume it's something to do with the clutch slipping during start-up then (I'm probably completely wrong haha).

No harm in giving it a try, although I would want to be very sure before changing the clutch as it's quite expensive lol

Yes indeed lol! As it already slips, then I imagine stage 2 will have eaten it up by the end of next year and after a lot of research I've decided to go down the Spec 2+ clutch & steel SMF instead of the Sachs Organic clutch & LUK DMF, as some people are still suffering with clutch slip with the latter at stage 2+ and Organic clutches can't handle drag/launches either. So I better start saving after this next batch of repairs.

I have wondered if it's my clutch that's causing start up issues as well, not disengaging fully.

I've started depressing the clutch as far to the floor as possible and there is slight improvement (my bite point is almost at the top of peddle travel).

Interested to see if it solves other folks issues.

After a little research then it does seem to be very plausible indeed. Since ownership my car has had a proper check over and a service from an ex-Audi technician at a Toyota dealership, as well as a few other bits & bobs done here and there but nothing has ever been picked up, however I've never got someone to specifically look into it so I will get Storm to do this.

Mines the same as yours where the bite point on my stock clutch (58K) is almost at the top of the peddle travel, what mileage is yours on? Also, what kind of problem do you suffer from with the start up? Mine cranks over between 2-4 seconds when it happens before properly starting up and everything is fine after that. Albeit not as frequent nowadays, it still has the intermittent start-up issue and to the best of my knowledge, I always have my foot fully pressed down on the clutch pedal when starting as this came to mind as well when trying to figure what the hell is going on.

I'll make sure to update this thread after Storm investigate on the 20th.

That was similar to mine before the clutch/dmf change, if I pressed the pedal to the floor and started the car t would start without a problem.

Have you had anymore updates with this issue? I have got a '08 s3 with 53k on the clock with the same sounding problems. Just had it serviced about 300miles ago with new plugs as well.

Is it just what some of these cars do?

Runs perfectly fine once it's going, I also warm it up and take it easy until it's reached temperature and warm down.

Did you get any info about the "hot start patch"? As I've noticed if I dab the throttle a tiny bit whilst it's cranking over it starts up straight away.

I haven't got any updates at the moment, although it's going into Storm Devs next week for other work to be done so I will mention it to them then. Most people who have had start-up issues with their S3 8P's sorted it by replacing either the battery, crankshaft position sensor or starter motor however none of them as well as replacing other parts have made a great deal of difference for me, except that the start-up issues are a lot less frequent now.

I'll speak to Storm about the hot patch next week, however that is for Diesels which are a completely different setup so probably not related and the fact that mine happens from cold as well.

 

[Max Read]

Ok mate, sounds good.

Fingers crossed they can help solve it!
Keep us posted!

You can say hello to mine while you're there.....

Andy has convinced me to do a few more things while it's in bits.

There aren't many things I can get so easily convinced on in seconds, but doings bits to a car is one of them, even if my bank balance doesn't agree which tends to be often!

Not when you see it in bits!

Andy is one of those rare people who will spend ages talking to a customer and trying to get things done right.
He managed to convince me that the hotside of the turbo actually needs to be a bit smaller,and that the inlet ports on the car need smoothing out where the old runner flaps used to fit.

It's more work,and more expense but cheaper done now when it's already being taken to bits anyway....

 

[HHS3]

A year has now passed since I created this thread and it's been well over a year that the problem has been causing me trouble, with still no light at the end of the tunnel in sight..

It had been a fair few weeks but last night I had two delayed start-ups yet again, both times with mates in the car and it's just embarrassing.. I absolutely adore my S3, I've sunk several thousand pounds into it since ownership and around £800 of that is me throwing money at it to try and fix this flaming issue! It's always at the front of my mind whenever I get in it, having to constantly worry about your car really does start to drain the fun out of it, especially as it's my prized possession

The issue definitely occurs the most when the engine is hot, especially if the weather is hot as summer is when the problem happens the most. However, it does have the odd start-up trouble from cold e.g. in the mornings before work (regardless of temperature outside), albeit these are far rarer compared to hot start-ups.

The only avenue I haven't explored much is the possibility of it being a clutch related issue. I will be getting my Spec 2+ Clutch and Steel SMF fitted later this year when my stock clutch goes as it's at 61K now and has been mapped for the last 11 months/6K of its life. I've seen a clutch bypass harness for £25 (http://www.ebay.co.uk/itm/152387058679) so I will give this a try and see how I get on, although given my luck on the matter, then I'm not hoping for much to be honest.

Failing that then I'll just have to send it into Storm for them to investigate. I don't know where they would start though as its such an intermittent/random problem. Has anyone got any suggestions for me to bring up with them prior to the work? Asking them to hook it up and do some datalogging is all I can think of?

Just to reiterate the main points below:

• Changed Coolant Temperature Gauge
• Changed Camshaft Position Sensor (Twice)
• Changed Crankshaft Sensor
• Changed Starter Motor
• Changed Battery
• Changed Spark Plugs
• Changed Coil Packs
• Fitted revised PCV and now Forge Plate Delete (Separate work)
• Fitted Rev G DV and now GFB DV+ (Separate work)

• Nothing has come up in Services, MOT's or a Visual Inspection Test
• Hooked up to diagnosis equipment several times for separate work of which no fault codes have been given related to this, currently got no fault codes present

• I let the dash do a full sweep before starting the car up
• I never boot it from cold and always let the oil reach 90 degrees before ragging
• The last minute or two of driving is always slow and if I've been tearing it then I'll also idle for 30 seconds after the final slow drive before turning the car off

Thanks.

 

[S3Alex]

HI...I can see the sort of problems you've had there...

The problem as you already know is actually having something monitoring the car when the fault occurs.
We had a problem on mine a few yrs ago with the car suddenly running very rich,and overfuelling by about 20%.

In short,there were faults with the MAF/MAP sensor/Lambda probe/thermostats,and not one of those threw an error code.

The eventual problem was found by logging my car Vs another S3 and looking for differences,and on that,the throttle body was found to be faulty.

It is like looking for a needle in a haystack.
Good luck!

 

[kash_v]

Fuel filter been changed?

Also, how many cranks we talking? Try get a vid?

 

[Max Read]

A random shot in the dark.
I had issues with starting on my 08 S3. Turns out the timing was slightly out. Alex at AKS found it when it went to be mapped. A pin in one of the pulleys had broke and caused the pulley to slip out of place a touch. Very relieved he found it and didn't cause any permanent damage (as far as I'm aware). Anyway since it was fixed the car starts without problem whether it's hot or cold.
