Hi guy's, since a few weeks I've had the issue of the car not reversing.
It will go in to reverse and i can feel it does but it does not move. It's like having 2 neutrals.
so every time i have to push the car back.

I read quite a few forums but couldn't find anything about my problem.

The gears going forward are still the same as before and have no issues whatsoever. I also read if pushing it in reverse is difficult, but that is also not the case. Under the transmission is completely dry and no signs of leaks. Oil is all good and on level and did a flush 20.000km ago. Checked all the fuses and are all fine.

This problem occurred when i had to reverse a few time back to back. I turned the car on and the car was maybe running for around 3 mins. So someone was blocking the road so i had to squeeze through.
because of that i put it multiple times in reverse. After a few times it would not reverse. Me thinking the wheel was stuck or something giving it more gass but nothing. So put it back in drive and back in reverse, it reversed again. Put it again in drive and reverse and after that it never reversed anymore.

so i went to the garage and let them read the faulty codes. These we're the following codes:

P1796 Malfunction - CAN controller circuit (bus out)

P1797 Malfunction - CAN Transmission Control Module to ECM

P1799 Malfunction - CAN Transmission Control Module/ABS-CM Circuit

(Had to translate, it may be not completely the correct translation)

(Car info: x-type 2002 3.0)

I hope you guy's have any idea what could cause this. Thanks in advance.
