E250 2011
7g tronic problem
Hi all hope you're all well. I've got a 2011 e250 Cdi bluemotion. Engine management light is on. When diagnosed the following is showing,
- 0778 : the internal electrical check of component y3/8y5 (B1 Brake solenoid valve (VGS)) has failed to read and observe repair information)

The car goes into limp mode I think and hits when changing gear, this happens after driving the car after 20 miles(hot gear box) but when the car is cold it is fine.???



Any suggestions welcome

Sory for language on photo from diagnostic but down side have a English.
