2004 Mercedes-Benz S430 Problems

Failed Valve Body in Transmission

The valve body mounted inside the transmission fails causing the transmission to fail to shift. The problem usually starts with a hard second to first downshift.

trunk will not open

I have not had this problem fixed. I was wondering if anyone out there had the same problem. I can't get the trunk to open using the key or the remote.

Poor AC performance Due to Evaporator Temperature Sensor Failure

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

Crap crap crap. this is the worst car I have ever owned. Every 3-4 months its another trip to repair shop. I think I have funded his new boat. Cranks sensor, SRS error, random noises in front suspension, a/c not working, sun roof error won't auto open/close. The list goes on and on. Never a MB again.
