Hi all, the wife bought a used A4 2.0 tdi 143 on an 08 plate yesterday . We drove the car from York to South Wales car drives very nice indeed however on the way back a couple of times the warning flashed up on the dash stop check coolant level as the temp gauge was showing near the max, stopped the car immediately and the coolant level is perfect same as when we left on max. Temp gauge as we were coming off motorway and stopped moved back to 90 no problem. Drove car for another few hours and the gauge was slowly fluctuating towards the high mark but then dropping again to the 90. The engine was not overheating and temp in cabin for heat of we wanted it all working perfectly.
I am thinking faulty sensor or thermostat can anyone give me advice on what they think please ?
Thanks,
Si
 
Hi dentsy, I had a similar problem on my mk4 Golf Gti Turbo - Coolant was topped up, fan was working coolant system/pipes were full but after about 10 minutes driving, the temp needle would go off the scale and warning lights would come on. Turned out the impeller had come away from the pump so, although everything was full, the coolant wasn't circulating, hence the overheating! Didn't cost much to fix either, so fingers crossed it's as simple as this or a sensor.
 
its going to be the water pump
so its really a cam belt change aswell
when was the belt last changed as the water pump should really be done with the belt ?
 
stat will normaly make the temp drop below 90
 
Belt was done at 64 k car done 81k nothing about a pump, car heating circulated perfectly tried again today coolant is fine got up to temp drove for a hour temp gauge perfect . Lots of heat in the car when you need it , so possibly not the pump ?
 
A scan should show up any issues, past & present unless cleared before you got it, I'd get a print out of any faults and get straight back to the dealer you got it from. The warranty may not cover every thing but any dealer, IMO, should sort out faults given that you've just bought the car, other option is tell him to stuff his motor and get your money back, lol.

Mm I hope it don't come up that I spoke to him this morning and said that we have this problem so he have me the warranty company details, I also told him no spare wheel in boot and he said he will get back to me ASAP, it was a 500 mile round trip to buy this car
 
Hope it doesn't come to that either dentsy, keep us updated re how you get on with the warranty company, in the meantime though, I'd defo get it scanned.

Kinda why i don't go too far to get a car.

Had my belt and water pump at the same time at 133k on the clock costing £549. Now I've got free MOT's for life at Audi.

Hope you get this sorted!

Just had a read on the net isn't there a small secondary pump too a little black one ?

Normally the small secondary pump is electric and it is a "run-on" pump, ie runs only after you have stopped the engine to keep the water circulating for a short period.
 
This is just me working on basic principles, if the impellor is loose/off, the water will still "move" a bit and hot water will mix with the cold due to thermal effect, so you might just still get enough heat in warmer weather. Someone can shoot me down if they have experienced otherwise when the pump impellor was loose/off - if so then both of us will have learned something!

Edit:- I'm not sure that VAG cars have a small continuous flow of circulating water back into the header bottle, if so, you could look to see if water was really being pumped round the system.
 
id don't think stat for 2 reasons

1 its stuck open it will get to temp in slow traffic and drop when moving fast.
audis normaly get stuck open when stat fails.

2 if its stuck closed then it will overheat with a long ish drive.

when the WP starts to fail. its like you have posted.
if it is the pump and you carry on using and it does go you could be looking at quite a few ££££££ to get fixed unless the warranty pays out and that's a big IF.

a scan is good but will not bring anything up for the pump or stat.
it may bring past codes up.
so if you get any codes clear them up and rescan after a drive.
if warranty fails to deliver on any repair get back to the dealer don't listen to his **** he has got to repair as you only just bought it.

im in barry next Saturday if you need it scanning.

Hi all, have I missed something here but are you all assuming the impeller has detached itself or is there proof of this?

If the dealer did any work on the car prior to selling that included draining and refilling the coolant, if just a coolant swap for maintenance reason then there could have been an air block which would behave in the exact same manner. It’s worth asking before you point the finger otherwise you will never get a straight answer, just a defensive one.
 
"No spare wheel" - you may have to chalk that one up to experience. Unless it was advertised as having one the seller will have no obligation to fix that.

The warranty co. may refer you back to the dealer as the fault was obviously present in the car at point of sale. Dealer has a duty to provide a satisfactory vehicle (SOGA) BUT you have to allow them to rectify the fault. You can't take it somewhere else and send them the bill.

It's a bad position, but - once you've a good idea of the costs involved - I'd negotiate with the seller for a contribution to fixing it, unless you fancy driving back and forth to York a few times.
 
Surely they have to sell a vehicle with a spare wheel as it does not have run flats or an emergency kit. Anyone know any dealings with the warranty company called the auto group ?
I have an Indy right on my doorstep who is very reasonable but I. Know that some warranty companies state their repairers are autocentres lol, what do they know about audis they prob never heated of vagcom either lol
 
Dealer ordering spare wheel off eBay for me now, also the temp sensor not done it since all working perfect .
Got it booked into my Indy third anyway to get it looked at.
Warranty will use any local vat garage

Hi all, ok here is the outcome :-
Car went into Indy he diagnosed a slipping water pump. Spoke to warranty company and they said it's covered but max payout per claim is £300, total cost of job is £477.00 as the timing belt has to be changed along with thermostat and a gasket, warranty company authorised the claim but will not pay out for the timing belt kit or the thermostat. I asked them why as the used belt can't go back on or is that what they are telling me to do ? They said oh no we are not saying that but we do not cover so called good practice . Spoke to the dealer again and he said ok no prob I will pay the £100 difference so warranty company £297.
Dealer £100
Me £180
It's only cos I have stipulated oem parts not done cheap crap from a motor factors.
Not a bad result overall and spare wheel arrived today in post
Obviously this is a good garage to recommend they have been brilliant
Used car 123 in York well done !!!!

You would recommend ?

Really ? They should pay what the warranty company didn't pay.
 
the dealer should have put all this right with no cost to you

he should have picked up the rest of the bill and sorted it.
 
Hi all, just an update , car running fine until today when I drove it noticed that the temp gauge is sitting at around 70 it tries to creep up to the 90 but then goes back down sometimes to as low as 55 . Engine was hot and at motorway speeds and stationary in traffic. Could this be the temp sensor as all other bits w pump inc thermostat was changed a few weeks ago . Coolant level is perfect and heaters in car seem fine even though obviously we are running air con at mo for cooler temps,

Thanks,

Si
 
Only thing I can suggest is change temp sensor and see how it goes, could be costly if it doesn't fix problem. Another thought is, see if you could get another member to lone you their temp sensor for a day, to see if it makes a difference, or fleabay, maybe scrap yard.

Ok cool will look at temp sensor then , can't really see that it could be anything more serious as coolant level is perfect all the time and car not running hot. How could it be costly do you think matey if it ain't that as all other bits changed ,

Just meant that you buy a sensor and it's not that, money wasted, then you still have to sort the problem, more £££'s. :sadlike:
Good luck at the garage matey.
