    So a few weeks ago I get an Check Engine light come on when I was driving normally. Car ran fine but plugged in the laptop armed with my ebay cable and got the following code:

    17544 - Fuel Trim: Bank 1 (Add): System too Lean
    P1136 - 001 - Upper Limit Exceeded

    So as the car was running normally I reset the code and drove it to see how quickly it came back. 80 miles later it came back on. So I cleaned the maf with some isoprop and then checked the logs for the maf and lamba's and everything seemed normal ish and so I cleared the codes again. This time it took 100 miles until it came back on and I checked it and it was still the same code and so as I was going away for work again I just left the car parked up.

    Got back last night and started the car this evening and the car had a judder and the check engine light was flashing. drove it up the road slowly and the car was obviously not happy so I drove straight home plugged the lappy in again and this is what I found:

    4 Faults Found:
    17544 - Fuel Trim: Bank 1 (Add): System too Lean
    P1136 - 001 - Upper Limit Exceeded
    16594 - Injector: Cylinder 1 (N300): Circuit Malfunction
    P0210 - 004 - No Signal/Communication
    16690 - Cylinder 6: Misfire Detected
    P0306 - 001 - Upper Limit Exceeded
    16700 - SAE - Engine Misfire Detected on Startup (First 1000 Revolutions)
    P0316 - 001 - Upper Limit Exceeded

    Now I did notice that when the engine was last taken out and the inlet manifold was changed the Barstewards broke all the injector connector clips down one side :motz:So I am going to take that loom off and fix them but what else could be causing the problems? could it be coil pack on the cylinder 6? and dodgy injector on cylinder 1?

    may sound like a silly question but looking at the engine head on which is bank 1 and how are the cylinders numbered?? Also there is alot of talk in the USA of a coil pack recall! apparently there is no recall over here but why not? surely we use the same coil packs on our cars as they do over there!

    Thanks in advance,

    Sam

    Hmmmm more troubles eh mate :(

    Have you tried one of the more specific S type forums, you might have more luck there?

    PS I was supposed to be looking up something for you on Etka, what was it?

    Yeah if I didn't have bad luck I'd have no luck at all!

    I did try and post on another S forum but it seems my membership is no longer valid!

    I'm good for Etka thanks James got it all sorted :thumbsup:

    Sorry to hear that you still having trouble with this Jinxed machine, such a shame aswell...
    Get yourself onto Rs246 and Audisrs and you'll defo get the S heads involved. I thought the 1,8t's were bad but read up some of the issues they have on there, some are frightening but very knowledgable :o.k:

    Oh no more problems. :(

    As above, RS246 and AudiSRS would be a good place to ask. If you're having trouble posting then I can do it for you if you want.

    Well I did use to have an account on rs246 but now it doesn't seem to let me log on and won't send me a new password! so I tried to register again and it won't let me register saying the question was not correctly answered!! maybe its just something on my work pc so I'll try it again at home but if I still have troubles I might just take you up on that Kind offer Bill :icon_thumright:

    Currently to try and sort the car I have ordered 8 new coil packs and I am going to change all the injector connectors on the side that are broken as that I hope is the cause of the injector fault!

    I am a bit pissed off because I did take the car back to Kartechnics saying that it was hesitant (which I now know was a misfire) and they fobbed me off saying it was fine and running normally! and now that its got to the point where the car is not drivable the warranty has run out!

    Well a bit of good news, today I picked up 8 new coil packs and 4 replacement connectors for the injectors and its now running flawlessly revs smoothly with no hesitation at all! :happy:

    Coil packs were straight forward enough to fit. had to loosen off the coolant expansion tank and had to take off the top of the filter housing on the other side. I probably could have got away with just changing the coil pack on cylinder 6 but judging by the state of the coil packs in there I am glad I changed them all. and the injector connectors you could see why it caused a problem as they weren't fully sealing off and some moisture had got in. So now I will just wait and see if the CEL comes back on for the lean fault again or whether that was all down to the coil packs

    I'm loosing alot of faith in this car and am not sure if I am going to keep it much longer, might trade it in for an rs4.... but b7 :ninja:

    How's the S4 running now, hopefully the work you've carried out has done the trick.

    Well today I drove it into work and it was the first time I've had a chance to drive it since the test drive after changing the coil packs and its like a new car! :yahoo: So I am chuffed that its sorted! Also the range went up from 85 miles to 95 miles by the time I got into work which is a 30 mile journey :think: and it usually drops fairly rapidly when it has 1/4 of a tank left! so hopefully I should start seeing mpg up in the mid 20's now

    Another thing I have noticed is that the goodyear f1 asym aren't half a nosey tyre! I could hear a drone at 30 mph and thought oh no what now but its the tyres! anyone else noticed this with these tyres?

    Well after the car being well behaved yesterday I was greeted by the CEL on my way into work this morning... 3 new fault codes that I haven't seen before

    3 Faults Found:
    16591 - Injector: Cylinder 7 (N85): Circuit Malfunction
    P0207 - 004 - No Signal/Communication - Intermittent
    17547 - Fuel Trim: Bank 2 (Add): System too Rich
    P1139 - 001 - Upper Limit Exceeded
    16508 - Throttle Position Sensor (G69): Signal Intermittent
    P0124 - 002 - Lower Limit Exceeded - Intermittent

    The idle was very lumpy so I disconnected the MAF and it ran normally so looks like i'll be getting a new one tomorrow! it seems to be one thing after the other at the moment :(

    I haven't noticed any tyre drone but then I don't know what it sounds like on any other tyre as they were on when I bought it.

    Oh FFS. :( I know nothing about how this stuff works but is it possible that there's one underlying fault that's causing (or contributing to) all the others? I just can't believe that you're this unlucky!

    the drone is pretty noticeable on my car! and very annoying as well!

    I think the reason why all this is happening to the car is because after the timing chains were changed the engine was truck washed and then rinsed with a pressure washer! do you think I would have a case to claim some of the money back that I have spent on parts?

    Well after a few weeks of changing different things and the fault code still coming back I think I have finally found the cause of my running lean and lumpy idle

    [​IMG]

    There was a hissing noise in the engine bay and whilst trying to trace it spotted there is no hose clip on this pipe!

    Also I believe the droning now to be the front nearside wheel bearing. anyone know how much a decent indy would charge to change one?

    And a little project for this weekend I managed to get a used set of down pipes which I am going to gut the cats out to free up some horses. Will be a bit of a novelty doing something for my car that doesn't involve fixing a problem!

    Result! A nice cheap fix for once :)

    For a wheel bearing I'd guess at a couple of hours labour and a £50 part?

    I've got it booked in to a place called independent garage services in eastleigh for Thursday, VW audi and Porsche specialists. Any one heard of them. Also had the lean code come back again so now I am wondering what else they left off so going to get them to do a vacuum leak test on it as well

    i used IGS to service my A4 a few months ago. Seemed like nice knowledgeable people and reasonable prices so will defo take the car back to them when i need some work. infact might see if they can have a look at my poor starting issue.

    Hope they help and get your nice looking S4 up n running as it should be.

    Well the offside alloy was buckled so they have put the spare on. but its knackered the wheel bearing. The haven't changed it yet as I needed to get home so its booked in next week to have that done and also he says the vaccum hoses hasn't been put on right so he is going to sort all those out for me. One of the vaccum hoses which is meant to go back to the air filter housing is just blanked off with a screw! so that can't be good for it.

    So at least I know what it is and this time next week it should be sorted! So there is light at the end of the tunnel, or there is a train coming!

    Ive been following your nightmare since you bought this car, I hope you can start enjoying the 'S4' once these last niggles have been corrected. I cant help but fell sorry for you mate, we all know what its like when you get just one problem with our motors but you've had the fair share thats been going on .....and on for months. How do you sleep? Do you have a VagCom
    I have and im forever plugging mine in for a scan, at this rate ill need a new socket and lead!...dont know whether im collecting a disorder or not :blink:

    Good news then. Couldn't agree more, lets hope the S4 is sorted once and for all Sam and you can really start enjoying your car.

    J7USS, I know what you mean about possibly getting a disorder with the vag com, i borrowed a lead from a mate at work for a couple of weeks and was scanning every day.

    Cheers guys, This car hasn't been good to me so far. Yeah I have vagcom its a god send! I still get to enjoy the car now and again as it currently drives fine but its a bit soul destroying when the CEL comes back on again after I thought I'd sorted it. Fingers cross that once the vaccum leak is sorted then that'll be trouble free motoring for a while!

    I've got spacers to trick the lambdas. I haven't put them on yet or even gutted them. Was bit of an impulse buy as they were cheap and on my last audi both cats went and audi wanted £800 for each cat

    Hi.

    I use IGS as they're literally a few hundred metres from my house.

    I first went there when I smelt fuel in the cabin (see here) and it was diagnosed in under 10 seconds.

    I've used them three times now and it's mostly been for issues relating to the way it had been treated by former owners:

    1. Fuel smell in cabin was result of fuel rails being removed without replacing the injector seals with new ones.
    2. Engine misfiring was the result of knackered connectors in the injection circuit.
    3. Air con not working due to damaged pressure sensor - unfortunately this involved taking the whole front off.

    Each of those visits lead to £200-300 bills.

    Apart from that my S4 has been sweet - as long as I don't mind visiting the petrol station. Although I got used to that with the Impreza. The only thing now is, having the MPG display, I spend most my time trying to keep it in the 20s.

    I've noticed on 6th gear cruise it'll rest at 30-42 so I'm hoping to get an average of around 30 on my trip through France in a few months.

    Urban stop/start driving gets me late teens and foot-to-the floor I see 5! Not for long though thanks to the power/torque.

    Such a nice place to sit in too. Hopefully you'll get the full experience soon. What day are you booked in for?

    Thats handy them being across the road from you. I work over on brickfield lane in chandlers ford so its not to far from there. Its there with them now. They have changed the front wheel bearing and found a split hose on a vacuum line. they had to wait for the hose so I'm picking it up tomorrow afternoon.

    I might have to pick up one of those VAG-COMs too. How much did you pay for yours? Also, are there any 'features' you can turn on/off that might be of interest (such as auto-door lock, which I have now)?

    Ditto, I self diagnosed an aircon problem without a vagcom, but since I have two VAG cars in the family now (Had 7 over the last 10 years) I think it's high time I went out and made the purchase.

    Any pointers to where's best to get it from would be appreciated.

    P.S. I've been following the thread too, and hopefully you'll be a happy bunny when you collect it for the last time later today .

    I've just currently got an ebay special that cost me £10 iirc but I plan on getting a genuine one. Mine can turn off autolock if you want me to do it for you, and do the basics and read fault codes and stuff. I even managed to reprogramme my RNS-E with mine that I read could only be done with a Genuine cable.

    Thanks Phil me too. Your best bet for a lead is if you PM "NHN" on here as he sells the Genuine Cables

    Thanks but I actually had IGS turn it on for me. I was wondering if there are any other features along those lines I don't know about that could be changed.

    Well I have picked the car up and so far so good! the part hadn't come in so they have put a temp pipe in that will stop it running lean but they will call me when its in and I'll drop it down there. Its idling nice and smooth as well and the hesitation has now gone completely. Its also nice to drive around without the drone of the wheel bearing.

    So this weekend I'll be removing the resonators in the exhaust to unleash the full fury of the V8 and I'll look at how difficult it will be to get the down pipes off and contemplate gutting them (for off road use of course)

    Hopefully its the last of the problems thread for this car and all the niggles have been fixed. The good side of all this though is I have learned a fair bit about audi v8's
