AZURES3 Posted March 13, 2007 Report Share Posted March 13, 2007 Started it up this evening and the engine management light came on and did not go out. I called Audi roadside and they said that as long as it is not misfiring or had loss of power I am ok to drive, they suspect it is dirt in the petrol or similar. Drove the 20 miles home and no issues or loss of power, called the dealer and they advised to get it booked in but no mega rush as its not misfiring and its only a warning AZ Link to comment Share on other sites More sharing options...
shark_90 Posted March 13, 2007 Report Share Posted March 13, 2007 The engine management light will come on if it detects a fault and won't go off until it's cleared, just like the airbag light. Even if the fault isn't present any more (i.e. a single misfire, or dirt in the fuel etc) the light will stay on until the fault is cleared from the memory. If it's driving OK and not backing off as you drive or hesitating, I think you'll be OK. If you're concerned, call Audi Assist again and insist they come out.

stevie_d Posted March 13, 2007 Report Share Posted March 13, 2007 Bugger, sorry to hear this mate. I'd do as Shark says, call Audi Assist out if you have any concerns Link to comment Share on other sites More sharing options...

S3ENVY Posted March 13, 2007 Report Share Posted March 13, 2007 Sorry to hear AZ! As mentioned however, if it's not mis-firing, backing off or going into limp mode you should be okay. For peace of mind however I'd insist Audi Assistance come out to have a look. It's a brand new prestige car and it's one of the perks you pay for, all he's gotta do is plug it up and then at least you know what's up with it! Best of luck!

Woppum Posted March 13, 2007 Report Share Posted March 13, 2007 Might be an emissions problem, or a dodgy lander probe Link to comment Share on other sites More sharing options...

S3Rob Posted March 14, 2007 Report Share Posted March 14, 2007 Hope your S3 is ok AZ If you can't feel anything wrong then it's probably a faulty sensor/loose wire type problem. You would be able to feel a flatspot or problem with the engine clear as day on full boost. Link to comment Share on other sites More sharing options...
lottiefox Posted March 14, 2007 Report Share Posted March 14, 2007 AZ get Audi Assist out - its what they are there are for and they can run a scan and you'll know what it is causing it. As said, a single error that has now gone can cause the light to stay on but it is best to check it out IMO. Keep us posted. Link to comment Share on other sites More sharing options...
TheReverend Posted March 14, 2007 Report Share Posted March 14, 2007 Lottie's right on the money with this one. Might be nothing, could be something. But you paid top whack (no offence) for a proper car from Audi and part of the new car experience is when something goes wrong you want them there on the spot. If you're not going to take advantage of it why buy a brand new car from someone like Audi? march 'em out to your place and get it looked at and sorted to your satisfaction!

AZURES3 Posted March 14, 2007 Author Report Share Posted March 14, 2007 Called Audi Roadside at 16:50 and they arrived at my house within 50 minutes Plugged in the diags and he said things are not looking good. He was a really nice guy and seemed very knowledgeable, first S3 he had seen in the flesh. He showed me the report and said it will have to go in as it is showing mutliple fuel system faults. He said it was very unusual as it is showing the Lambda & MAF sensors as being faults plus a few other things. He did say is could just be the Lamdba or the MAF but he was worried it might be the ECU due to the level of faults I have to take it to the dealer tomorrow as it is ok to drive on short journeys but dont thrash it. He asked if it had been using more fuel, I mentioned that since run in it has never achiveved the MPG figures many others receieve. The day before the light came on it averaged 18.3 MPG on a 22 mile journey and I was not stuck in traffic or thrashing it either RAC car hir on behalf of Audi called me afterwards and advised that I will receive a call tomorrow when the Audi car is available and I can do a straight swap. I have to pay a £300 refunadable deposit for the insurance and fuel. I can see it being in the garage for a while so I am going to insist on a vehicle condition form being filled in for my car, they always seem so concerned about the loaner but what about my shiny S3, so I will insist on a form I hope this is not something really bad AZ Link to comment Share on other sites More sharing options...

lottiefox Posted March 14, 2007 Report Share Posted March 14, 2007 What a woe - your poorly car. I'm sure it won't be anything serious and in some ways the turbo engines do seem prone to these sorts of faults (my TT has acquired a loud hissing noise today into the cockpit of the car!! Me thinks boooooost leak!!) - see what the dealer says and if it is something major then think about rejecting, but I guess things can go wrong. Hopefully it will be back on its four lovely wheels before too long. I know how horrible it is though when your pride and joy is sick. Link to comment Share on other sites More sharing options...

PetrolDave Posted March 15, 2007 Report Share Posted March 15, 2007 [ QUOTE ] [ QUOTE ] lambda [/ QUOTE ] Thank you, and maybe these will be of help sir!: [/ QUOTE ] I'm sorry for you that correcting incorrect word usage makes you so uptight. Correct word usage is vital to making communication between people work. Let me give you some recent examples, on this topic and others ... ...lander probe = something that British scientists crash into Mars at very high speed. ...lambda probe = something in the exhaust of all modern petrol cars that senses the level of oxygen and which is used to adjust the engine fuelling to ensure the catalytic converter is able to work efficiently. Not "quite" the same thing ..... When the story about dodgy supermarket petrol first broke some journalists talked about "silicon" in petrol and others about "silicone" in petrol ... ...silicon = an element that is the major constituent in sand and from which most microchips are made. ... silicone = a vast range of complex chemical compounds, including one that is added to petrol (in very low concentrations) as an anti-foaming agent. Again, not "quite" the same thing. Recent fuel problem stories ... ... owner of a Peugeot 306 DTurbo told his lambda sensor had failed due to the faulty diesel and needed replacing at approx. £300. Huh? There isn't a lambda sensor on that car, and the problem didn't exist in diesel. ... owner of a Nissan Micra told that the faulty petrol had caused her engine ECU to fail and needed replacing at nearly £1000. Huh? The ECU is not in contact with petrol (and hence the unwanted additive), it's only the sensors that get contaminated by the unwanted additive. These show how a lack of understanding of technology issues contributes to "rip off Britain". My wife handles the outgoing post for a major financial institution, and she sees many "howlers" in addresses each week - recent examples ... "Norwich" spelt as "Norage" "Louis Pasteur Drive" spelt as "Lewis Pastures Drive" - an insult to a great scientist whose work we benefit from every day (pasteurised milk?) Correct word usage, spelling and grammar is what has enabled, and continues to enable, us to create and live with the complex technological world in which we live today. If we let word misuse become the norm then meaningful communication will break down, since nobody will understand what on earth others are talking about. Sorry about the "lecture" - but if people cannot accept well intentioned correction of their mistakes (we're all human, which means we are all imperfect) then we might as well all give up straight away and go back to living in caves dressed in smelly animal skins (because we won't know how to cure them to turn them into leather). Anyway - let's get back onto the topic of getting Azure's S3 fit and healthy again ... Link to comment Share on other sites More sharing options...

AZURES3 Posted March 15, 2007 Author Report Share Posted March 15, 2007 Audi CS called me this morning to say a 56 plate A4 2.0 avant will be ready for me at Guildford Audi at 1pm. Please tell me they dont make a normally aspirated 2.0 anymore When I called the dealer to book in my car they couldn't look at it until Monday so I suspect it will sit around all weekend. I am definetly going to push for the vehicle condition form for my car as its spotless at the moment. The S3 has been running very quickly recently with low MPG and major lift off burble the technician that came out last night said it was like it was running really rich and hence the low MPG.

DigimeisTTer Posted March 15, 2007 Report Share Posted March 15, 2007 Sorry to hear of your woes AZ Not at all good on a spanking motor. I can't see any grounds for rejecting it at this stage providing it can be rectified which i'm sure it will. Just the inconvenience that annoys - i had my wastegate solenoid fail on my TT when it was only 2 months old realised something was very wrong when i was comfortably blown into the weeds by a ford focus Hope you get it sorted fella.

[/ QUOTE ] Thanks, glad I didnt get it chipped as I suspect they would have riggled out of paying. It has made me very nervouse about chipping it now If the A4 Avant is a normal 2.0 it is going to seem like a real pig, just checked they push out 130 BHP maybe it will be the 140 BHP Diesel which would be more fun and no doubt quicker. Or even better the 170 BHP AZ Link to comment Share on other sites More sharing options...
sitas3 Posted March 15, 2007 Report Share Posted March 15, 2007 Just remember its just a car and it will probably be something or nothing! Dare I suggest you unplug the connector on the MAF sensor and see if the problems go away? This is a quick easy test. Link to comment Share on other sites More sharing options...
