The fault
How you spot it
The front bearing of the mechanical supercharger on the 3.0 TFSI, the nose bearing, wears, and over the years and the kilometres it drones louder and louder, but only under load. If the bearing seizes, the supercharger is destroyed inside. You will not hear the noise with the engine idling, so the test drive has to include a firm acceleration.

How we know
Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
