A8 Gearbox Fault

I had a similar problem with my 1997 A4 2.8Q. One day, suddenly, all of the gearbox indicators lit up. The car would relunctantly shift from gear to gear; it always felt strange though. And it would not shift to the top gear. My car would reverse though, with a big clunk. My mechanic simply reset the switch that tells the computer what gear it's in; I think it called the multifunction switch (I forgot). Maybe you can have it reset or replaced. It worth a try.

I'm not sure though, if we have the same problem. Try another mechanic perhaps.

Sounds like electronics to me. Can you find someone to get it on VAG-COM or a 1552 analyser (or whatever the correct diagnostic tool is for an a8)?

The gearbox control unit believes there to be fault, and has gone into 'limp' mode.

Has the garage actually checked the diagnostic fault codes? The CU should be reporting what it believes the fault to be. In the first instance, just resetting the fault codes may resolve the problem.

You need someone with access to the VAG-COM software/cable, or similar.

I have this, but Reading is probably too far to travel - someone in the Nottingham area must be able to help. Can I suggest that you register with

Whoops, that should have been

Thanks for the help everyone, I have asked on tyresmoke.net and a few people have replied, they have the same opinion that it is probably electrical and to check what the fault codes were. I have been back to the garage and they tell me the fault code was "Shift solenoid locked" I don't know if this helps anyone to give any more suggestions but all help is greatly appreciated.

Geesus, it's pointing right at the problem. Are they waiting for the tool to draw a fecking "X" on the bad part for them?

For god's sake take your A8 to someone who has a clue!
