RE: this thread
I've just booked the car in for the 3rd or 4th time at Audi for what I imagine will be the 'final showdown' with regards to my starting issues and their successive failure to fix it - and I'd like to be able to present them with everything we think it could be since theres more collective A2 wisdom here than any Audi dealer!
The symptoms -
Car cranks but does not 'fire'
Starts fine from cold
Happens generally when the car has been sitting between 5-40 minutes, but has been driven enough to warm up
Extremely hot weather seems to cause problem
Can start the car after multiple attempts and plenty of throttle bashing, often followed by smell of petrol or smoke from exhaust
Car sometimes unable to maintain steady RPM
Engine management light/EPC is intermittent
What has been done -
Full timing belt kit (April)
Lambda probe
Spark plugs
Recalibration of lambda probe and spark plugs
What it could be -
After much reading and research, I have:
Faulty crankshaft position sensor
Faulty camshaft position sensor
Dirty throttle body
A combination of these
(I suspect dealer hasn't checked these if they aren't giving error codes...)
Anything I'm missing? My current no.1 suspect is the crank sensor.
Cheers
