2006 Audi instant loss of power... Turbo?
Discussion
That sudden loss of power is most likely limp home mode.
If it had blown a boost pipe off or somthing, there would have been noise with it.
Yes it can be caused by a failed turbo, when the variable vains stick in the wrong position.
But it can also be caused by a number of different sensors going faulty giving an incorrect reading.
After an ignition off/on should be back to normal for a bit before the car notices the problem again. Is this the case??????
As ever first port of call is to read the fault memory and see whats stored.

Thanks for the comments. Think the plan is to take the car into Audi tomorrow to get a diagnostics test. Hopefully for him that will find the problem.
Cheers
Ouch! The dealers round here charge £70-£80+ just for the honour of plugging it in. I do it for one heck of a lot less than that Cheers

Problem is I'm now living in Norway, that's where the car is. And it costs almost £180 here in Norway just to plug it in.
Well its £80 for a boost pressure sensor Or £300 for an EGR valve or £1200 for a turbo.All with give identical symptoms.
The only way to know what the cause of the limp-home mode is, is to read the fault memory and carry out futher diag based on the code stored.

Yes but it gives him a 1 in 3 chance of only paying 80ish quid to fix instead of 180 to try diagnosrAll with give identical symptoms.

They were just examples, there are a host of other sensors or actuators that it could be, thet were just the most common.Its really pointless just throwing any parts at any car when you dont actually know what the fault is.
OK You could do the cheapest bit first, but what then if there is no change, the next cheapest and then the next?
After spending £350 find out it still needs a £1200 turbo. Or you could guess and spend £1200 on a turbo, and find it a split intercooler of a vacuum hose leaking.
Reading the fault codes is just the first step, then testing the car relevant to that fault code is the key.
Just as an example.
If you get a fault stored for MAF inplorsable signal, this does not usually mean you need a MAF sensor, it means the other sensors on the car suggest the reading from the MAF is incorrect. SO there is either a boost leak, some of the air measured by the MAF leaked out after the turbo and never made it into the engine. OR The EGR valve is jammed open, Exhaust gasses are replacing fresh air making the MAF signal unusually low for the load and rpm.
