Mercedes-Benz Turbo Actuator Repair Service

The Mercedes Electronic Turbo Actuator commonly fails on diesel engines causing lack of power and the engine to go into limp mode. We have a custom built test bench specifically designed for Mercedes electronic turbo actuators allowing us to thouroughly test your actuator before and after repair. Most turbo actuators can be rebuilt within 24 hours and come with a 12 month unlimited km warranty. 

Common symptoms include:turbo actuator
Lack of power
Engine goes into limp mode

Common fault codes are: 
p 2510 – 001 Check component Y77/1 (boost pressure regulator) Positioner signals fault.
p 2616 – 002 Check component B60 (Exhaust back pressure sensor) Control variation – Exhaust back pressure is too high.

If you were to purchase a brand new ECU / MAF the cost normally exceeds $3500. You also require coding via a Mercedes-Benz machine. Please note that if you purchase a second hand ECU it can’t be recoded via any diagnostic machine, even the Mercedes-Benz Machine can’t do this. If your unit has failed in a different way please contact us to discuss options, we can often repair this control unit for other failures and in some cases can transfer coding from your old unit to a second hand unit with our own special software.
