2006 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.

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.

Airmatic Pump Motor May Fail Due to Sticking Relay

The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.

2006 Mercedes-Benz S430 Reviews

Its a great car!
I love my S430. I think the body styling as well as the sleek interior cannot be duplicated. It looks, both inside and out, more elegant than the new, more aggressive S series. It ages well, and with proper service and maintenance, it can be a dream to drive.
