Help, problem with Audi A3 1.8T Sport Quattro
I’ll be well chuffed if any of you guys can come up with the answer to this problem. I’ve got a 99TQS and its running lumpy as anything, hard to start etc etc. Now, on the diagnostics machine it’s coming up with the following code:- PO341 (Camshaft Position Sensor, no plausible signal), I have changed the sensor but still the engine is running in safe mode, and the same fault code is still coming up. What gives?
It's not my car but a mates and he forwarded me the above text from his post on audi-sport.net. Anyone know what might be the problem?

Not sure, will find out. If not I assume we just disconnect the battery for a few hours and upon reconnecting the ECU has reset itself?

This fault can be caused by the header tank coolant level sensor failing believe it or not. I had exactly the same problem with my Leon Cupra which is the same engine...

Check your dump valve. Common problem on those engines.
If its gone, replace with a Forge recirculating one as it costs the same as the VAG part and is stronger!
Just an idea.

Just spoken to my mate and we are now looking at the wiring loom that is routed close to the turbo. Apparently this part of the loom weakens on cars 5-6 years old due to the high temps.
The car has been off the road now for nighe-on 9 months with all the major repair work done. The small gremlins we are now experiencing are really starting to frazzle the tempers of all involved. And we thought Audi's were reliable bullet-proof cars

Well, except for checking the coil packs and MAF sensor we have checked all the above and still it runs on safe-mode. Anyone got any more ideas???

to check coil packs, remove them, a broken one will be all burnt out. The early versions of these let go very regularly, if you do need to replace make sure you get the 'L' versions (product code ends in 'L')
Much harder to check the MAF without replacing it or lending one off a mate, but if it does come to this take your old one to Audi dealer who have a replacement policy on them, about £70 and your old one for a nice new one.
