Audi A3 ignition problem

My 2002 Audi A3 1.6 has recently developed an ignition problem. The engine turns over but doesn't fire up. This is a sporadic problem and tends to happen when the engine is warm ie when I have been driving the car, then park up for a short while. When I go to start the car again, it then won't start, but will do if I leave it for another 10 - 15 minutes. Any advice? Could it possibly be a bad batch of petrol, as this started since it was last filled up? The car had a new battery fitted in April 08.

    Thanks for the suggestion Yates. Two seperate diagnostics tests showed no probem but AA suggested it could be radio or similar waves affecting the immobiliser. Problems always happened close to the local airport and police headquarters, which might bear this out. Will have to wait and see. Anyone else experienced something similar?

Hello, the same thing happened to me with my A3 2006 1.6 Sportback, About 4 or 5 times and after waiting a couple of minutes the car finally started, but the last time it happened, the car never start.
I send the car to a Official Audi specialist, and they changed a blown fuse and the ignition switch/contactor, and apparently the problem was solved but now it happened again.
Do you know what can be the root cause for this?

Hi i have worked on car the AA have diagnosed and 50% they don,t get it right if its radio waves i would run up and down the street with nothing on it would seem when it warms up a few other things spring to mind that can be checked and not cost anything relays go faulty [starter] when warm and ignition coils do the same and when they cool down they function ok vapour lock caues the same problem but is rare as the fuel pipes would have to be close to exhaust but compared to radio wave interferece well less said if you grt to the point it drives you up the wall get an auto electrian to have a look hope every thing works out for you best of luck yates210456

Audi A3, 2003,starts and then revs and starts to cut out,if I rev it up it settles back

Yes, if you have some work done or a part replaced and a fault develops in the same system, then the replaced part is the most likely culprit. A faulty O2 sensor will alter the mixture and idle settings.

Engine has miss-fire

First check spark plugs/wires/distributor cap (tune up). Also would be good idea to use fuel injector cleane and change fuel filter and O2 sensor.
Hope that helps
Good Luck

Audi A3 2002 model auto - temperature gauge not working

The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.

2002 A4 Quattro 3.0 - Driver's door mirror moves randomly also auto dimming functions sporadically. Recently upon unlocking with fob this mirror's motors will continue to be energized until the ignition...

I only have the 2000 diagrams, and they do not have memory. Does your model save settings for different keys? If your system is the same as the 2000 diagram below, I would replace the switch. If you have a memory module, I would replace the memory module.
