Hello!
In my XF 3.0DS gearbox fault messages are showing sometimes randomly. Ive got the fault code u101 which means faulty connection to the tcm (transmission control module). Does someone know where I can find the tcm? Thinking of its maybe som moisture causing the fault codes?

Regards Rasmus

 

How is your battery? I've seen the gearbox fault flash up before when battery is dying...

 

Its a pretty new battery, shouldnt be the issue.

 

Well charged? Some people are driving much less at the moment and battery gets depleted and starts to give errors. (Ask how I know - didn't run my XF for a few wks and hadn't put it on the tender. So It wouldn't crank at the weekend...)

 

TCM is in the transmission if i remember correctly. There's a plug on the back of the trans for power and communication wires.
