Pressing hard on the accelerator pedal and engaging the Kick Down Sensor puts the car into Limp Home Mode. Problem goes away once the car is restarted but quickly returns when punching the accelerator and engaging the Kick Down Mode. Replaced the 'Throttle Position Sensor' and the problem was fixed.

Reported by trifendel for the Mercedes-Benz C230

I had this issue around 62000 miles. The transmission of the car fails to shift intermittently and the only way to get it shifting properly again is to park the car and restart the engine. The reason for this failure is because of certain transmission parts failing to get lubricated properly or are dirty. This also suggests that the transmission filter is getting clogged up.

I also replaced the radiator (Valeo) which are known to fail and leak coolant into the transmission, causing the torque converter to fail. Valeo radiators were used in early 2004 mod...

Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.

Reported by AFAULK for the Mercedes-Benz CLK500

It makes the whoe car haywire. Sparatic Enginle light, Abs warning, Esp warning, loss of speedometer sometimes, Brake Wear warning, Abs light. They can go away and come back. The best part is when you have these lights, the car will stay stuck in park, if restarting doesn't clear, you need a pointess pencil and the manua release is located through a little whole in your middle console (behind the little slide out drawer). What a headache!
