Really can't believe it. Went to collect car and it stalled as soon as I started it. Technician came out and car misfired badly. All they could find wrong is the cam sensors were caked up with carbon. They cleaned them last time and this didn't solve the problem then and it hasn't now. Thy are completely mystified as to what is wrong with the car and why it keep misfiring- has been misfiring on all cylinders.

Any suggestions???? :x

they say the coil packs are fine. They tested everything and found no faulty components. The cam sensors were covered in crap so they cleaned them then car was fine for a bit then back to square one.

They say this is very unusual and they have never come across a 3.2 misfiring like this. They say they have no idea what is wrong.

Don't know about the crank sensor. They said no error codes, everything fine. Can't believe they can't figure out what is wrong. I do find them nice people so not about to shout etc. They are waiting for advice from audi "central"

If the problem is intermittent it can be difficult to find. If no error codes are recorded then you are reliant on the fault being present when you are looking in the right place and sometimes faults can be little devils and play peek-a-boo :roll: .

The crankshaft position sensor G28 otherwise called the engine speed sensor measures the angular position and progress of the crankshaft. If the signal fails the engine will stop. If the sensor is loose in its mounting it can cause an intermittent signal and consequent misfire and rough running. It should generate an error code but in the case of multiple misfire the algorithm that detects rough running can be fooled.

Just a thought - it might not be that.

Scotland = TT :p

My TT was running like a bag of shite not so long ago, it was idling high and would cut out with no prior warning, sometimes at motorway speeds, I popped along to a local meet where some of the guys run vagcom and it threw up an error on the engine speed sensor, aka G28, got the part from a specialist, diy 45 minute fix, hasn't caused any problem since.

Thanks- they are still waiting for advice from Audi. They are nice people just wish the car was fixed. They said they would sort out a small dent free of charge. Overall I can't complain about the service. BUT I can complain about the car- really want to sell it as have had so many problems have lost confidence.

oh does throw out loads of misfire codes. The car is still parked where we left it outside the dealers. So I guess they can't get it started to move it. Just amazed they can't find the fault- yes it is intermittent. But it is also quite regular if you see what I mean.

Still I guess it was pretty lousy for them ie "here is your car Sir" then customer is unable to even get car to start + they are unable to move car due to it stalling/misfiring. One reason we went for a 3.2 was we thought it was more reliable. I've had CTR's a Supra, a celica, all were bombproof- hence my amazement that a main dealer can't fix the car.

get this- when the car broke down the audi master technician came all the way from......................................

across the road. He thought it was the coilpacks by the way but didn't know which one to change at the roadside. Then audi test the coilpacks and say "they are fine".

anyway- thanks for everyone's support. Think of us cruising Torridon in Scotland in an a4 sportback courtesy car when it could be the TT- I want to weep! :cry:
Well at least you can wallow in some fine Scottish malt - try Laphroaig - I designed the label - the first commercial job I did after art school... :p :p :p :p

Torridon is spectacular and very beautiful. Are you planning on doing some hills while you are up there ? Its the best time of year, before the midges wake up.

Hey, I was in Torridon last year :D . Great roads round there. There's a good walk up the road from a beauty spot car park - just follow the river up hill. Good for a swim if the weather's nice - some spectacular waterfalls and troughs. Check out The Old Inn in Charlestown for food and nice beer and music :wink: .
