Answer
So you just have the Trans message?I'm not sure how deep or if the garage can check.Having electonics running the transmission it is all controled bt an ECM and solenoids.With the scan tool it should be helpul to diagnose as long as they have european accessabilty.

I know the comment seemed a little hard to get but I'm not sure what type of scan tool your mechanic has to check the system.CAN(controller area network) is a high speed data transfer bus for the following systems Engine,Electronic Transmission,and ABS/traction system.The transmission circuit needs to be checked as to what fault it might have.152 isn't a code I am aware of,mostly the codes are a 4 diget number,sorry for the shortage of information.
