No error code yet. The car sometimes does not shift into higher gears. The w/s switch near the shifter will not work at that time and the manual shift "side to side" movement of the shifter will not change it into a higher or lower gear. In addition today after stopping at a light it took off in 2nd gear like it was in "winter" mode. It seems to be a electronic control somewhere but where?
RepairPal Certified shops can diagnose and repair your 2000 Mercedes-Benz S430. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
I recommend having a Mercedes-Benz dealership diagnose and repair the issue you are describing. It sounds to me like the shifter module has gone bad. Have you or anyone ever spilled anything in or around that area?
