Gearbox Malfunction
Hi Guys , new here, I hope someone can help/advice on the following problem with my A7 Multitronic 3.0 tdi
I have the dreaded "Gearbox Malfunction, you can continue driving " message.
Recently whilst driving in normal D mode, gears decided to change themselves from D to S4 and other gears randomly.
diagnosis from a garage computer showed 2 faults:
4322- P1891 - Signal line for tiptronic - Implausible signal
and
4323 - P1890 - Signal line for tiptronic - Electrical M
Hi Guys, please read my original post and note there is a technical service bulletin out for this problem of the coolant leaking.
Therefore if Audi deny knowing or ever hearing of this issue before, they are either lying or incompetent.
