What are the problems with the Mercedes throttle actuator?
Most Mercedes Benzes made in 1993 to 1995 have problems with throttle bodies also known as electronic throttle actuator or ETA. Most ETA’s problems are due to shorting wiring inside ETA loom and some due to internal components failures.
How much is the throttle actuator rewire on a Mercedes 600SL?
93 (600SL ONLY) 94-95 V12 throttle rewire – $450 each. IMPORTANT NOTE: some 94 and all 95 V12 units have internal motor design flaw. Motors brushes get stuck inside holders and if not repaired will melt holders. It is highly recommended to free brushes before they melt holders.
How does the throttle sensor work on a Mercedes?
Instead, there is a potentiometer that detects the position of the gas pedal. This signal is sent to the Engine Control Unit which analyzes the pedal position and several other sensor inputs which then sends the signal to the throttle body to open and close the throttle valve.
How much does it cost to repair a Mercedes throttle?
If you experience problems with your throttle body feel free to contact me and I will be able to repair your ETA. At Mercedes dealer new ETAs cost range from $1200 up to $5400 for V12 models each. And it doesn’t make sense to buy used ones as they use same biodegradable wiring insulation that can fail pretty fast.

Is the throttle actuator repairable in a non ASR car?
Some very few throttle bodies, about 1%, are not repairable due to wear and have to be replaced. Some ETAs, about 5%, have internal parts failures on top of shorting wires that can be repaired. In some cases shorting wires burn E-gas module in ASR cars and T/LLR module in Non-ASR cars.
