The fault

How you spot it

The Aisin automatic of the transverse engine VAG models locks the torque converter across a wide slip range, which gains on fuel consumption but loses on the life of the friction lining. The sign of wear is a vibration or "buzzing" felt at lock-up, and the lock-up cycling on and off.

The other branch is the valve body: the control bores wear, and from then on the pressure cannot be held. A fault like that cannot be fixed with new solenoids: the seller's argument that "we replaced the solenoids" does not solve the problem on its own, and the symptom comes back after a few hundred kilometres.

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.
