Transmission problems
Car went in to limp mode without warning. Diag showed the following: The internal electrical check of component Y3/8y3 (K2 clutch control solenoid valve (VGS)) has failed and y3 8s1 is not calibrated. changed 2 solenoids A2202771098 and replaced tcu A0335456732 with the A0335457732, but that did not solve the problem. Car is still in limp mode and doesn’t go in to gear. DTC C100 keeps coming up. Car is the Mercedes Benz CLS C219 500 from 2005. I live in the Netherlands/ Europe.
Has anyone else experienced a similar problem with this Mercedes model and this 722.9 transmission?
please let me know how this was solved Or any advice is welcome. Thanks in advance.
