2006 Audi A6 torque converter

Hi Betty Ireland,

Thank you for the donation.

If it is the torque converter, it could be the pressure or solenoids and is it safe to drive it would depend on the codes that was set.

Can you let us know what the exact trouble code is being set?
Do you have any driving or performance related issues?

Without the code, we do not know the actual fault with the torque converter. Under such circumstances we would have to list all the possibilities which would be a long list.

What is the engine and transmission type? A6 has a variation of engine and transmission models. The specific model would allow us to get the correct data.

If the code is intermittent, driving the vehicle should not be a problem. However when the code appears, drveability issues might occur. If the code had appeared and then goes away after restarting, you can retrieve the code which would be recorded in the engine computer. You can get a free scan done at your local Autozone.

The details helps in narrowing down the search.

The diagnostic provided by Audi are very vague and complicated. I have checked through some of them concerning torque converter problems and they are varied.

Some are simple solutions requiring replacement of the trans fliud or checking wire harness connectors.
Others requires replacement of solenoids or torque converter.

When a fault is present, rectifying it is the best option. Continued driving could result in damages to other parts and you might end up paying more for repairs to others related parts that can be damaged by the malfunction.

Without the Diagnostic Trouble Code, it is not possible to say what can happen.
