Dear customer my name is***** the expert who will attend you today, I am reviewing your query at the moment you are viewing this message, if you wish you can tell me your name, to know who I have the pleasure to talk to, also if possible I would like you to send me a photo or video in which your fault is better appreciated, it would help a lot to improve my final answer. If you have done a previous check or diagnosis in which you have obtained any error codes, that would also be helpful. Please note that the system will automatically offer you a service call, this has an additional cost to the initial cost of the consultation, and not in all cases it is necessary, so I recommend you to dispense with the call for now, we can continue through this chat without any problem. Thank you very much for trusting in the just answer.

Dear customer, have the connections of the speed sensor been checked?

Customer: replied 13 days ago.
He didn't touch anything, only connected his diagnostics computer to the car and as explained above.

Dear customer in my opinion there is a problem related to the OSS and ISS sensors, which are speed sensors, it is probably a failure of connections, if these are working incorrectly the gears will also fail, I have seen this problem in other vw and really the main reason for this are the wiring to these sensors, which may be corroded.
