3.0 TFSI: drone from the supercharger front bearing

critical

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.

What to check

  • Accelerate firmly from 60 to 120 with the window open
  • Watch for a drone from the engine bay that rises together with the revs
  • It is not audible at idle: do not look for it there

DL501 (7 speed S tronic): mechatronics and wet clutch

expensive

The 7 speed wet clutch S tronic used in the longitudinal engine Audis (0B5 / DL501) is more durable than the early DSG units, but the mechatronics unit is the most common source of faults here too. As the solenoids wear, the regulation of the hydraulic pressure deteriorates: harsh or missed shifts, delayed D/R engagement, and finally limp mode.

Show the rest

Alongside that, wear of the clutch pack gives shuddering and slipping when pulling away, and the dual mass flywheel rattles at idle. All three symptoms can appear together, and the fault code alone does not tell you which one is the trigger.

What to check

  • Pull away with a cold gearbox: there should be no shuddering and no clutch slip when setting off
  • Standing still, shift between D and R and watch the engagement delay: a 1 to 2 second hesitation is suspect
  • On the test drive go slowly through every gear, then under load too: the 2 to 3 shift should be smooth

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.
