The modern Mercedes C-Class from 2000 onwards is usually fitted with an electronic turbo actuator. The electronic actuator/wastegate is controlled by the engine’s ECU and is used to efficiently regulate the flow of the turbocharger and deliver precise amounts of turbo boost pressure. The ECU can be tuned to increase the power output from the turbocharger and simultaneously increase the economy of the vehicle.
Failure of the electronic turbo actuator is very common and can cause many problems on the vehicle. The most common cause of electronic turbo failure is the variable vanes in the turbo get stuck due to carbon build-up and when the electronic actuator tries to open or close the vanes the actuator gets damaged. Below we have compiled a shortlist of part numbers associated with electronic turbo actuators found fitted to the Mercedes C-Class:

Common Electronic Turbo Actuator Fault Symptoms
Some problems related to a failed electronic actuator include:
If your local dealer has diagnosed your vehicle with a faulty turbo actuator then you will be expecting a very high bill of at least £1200 to replace the turbocharger and actuator for a new unit. The actuator is not a part which can be purchased separately and, therefore, the only option is the replace both the turbo and actuator together. The alternative option would be to have your electronic actuator remanufactured by a specialist like Sinspeed and if needed, we can also rebuild turbochargers.
We’re able to fully test and rebuild most electronic turbo actuators and always use new genuine OEM components when rebuilding the electronic actuator to ensure all repaired units meet & exceed OE specifications. We carry some of the most common failing part numbers in stock and can be supplied on an exchange basis. All of our remanufactured turbo actuators come fully plug & play meaning no programming is required when refitting to the vehicle and are all backed by our Lifetime warranty.
Below is a list of vehicles we know that are fitted with this type of electronic turbo actuator. It is not a complete list so don’t worry if your unit is not listed in the table below, you can call us to confirm.
