Unless you like to buy parts and maybe get lucky and fix it. Start at the first point. Troubleshooting requires a process. No one is going to go oh I had that problem and all you need to do is buy this little part .Transmission control modules are known to be problematic not only on Bentley and Volkswagens but Mercedes Benz.

The trouble code presented on vcds is the reason this assessment. This is not to say that the module is the problem but if you don't check it and it is you'll spend a lot of time and money.

Don't overthink it, troubleshoot it. Only replace parts when confirmed they're bad. Theoretical repairs are expensive.

Regrettably Bentley service repair staff don't always abide by the above.

Yes that's where you want to start, because of a possibility of corrosion on the plug in. Only apply Dielectric grease to the plug connection.

Not too bad a project. Access to a lift is better than jacking the car up and lying on your back.


. FOOD FOR THOUGHT

To further the discussion I am not suggesting this is the case here. There is a printed circuit board, I believe not positive inside the transmission housing that goes bad. If my memory serves me correct Bentley service has sold owners a new transmission when only that component needed to be replaced. This is absolutely the case with certain Mercedes-Benz transmissions. I'm only putting this thought out there if this bridge needs to be crossed.

Vous poverais me respoder en Francais si t'il est plus facil ou efficace ? Enfain, je vous respoderais en Anglais, pour que des autres suivre des threads.

Translation = "Bentley was changing the transmission for an oxidized grip ????"

Please clarify.

The Bentley dealer is going to change the plug due to oxidation. The question is will it fix it.

Messieurs, je dois respectueusement déposer le thread à ce stade parce que je ne suis pas couramment le Français

Je suis heureux pour vous.

De rien.

La France ou Canada me manque .

Translstion:

I am happy for you.
You're welcomed it was nothing.
I miss France or Canada.

That plug and socket look clean as it could be, so please explain what you mean by "works better without the default code", what code are you referring to ?
