MERCEDES Turbo Issue CLS 320 CDI

by | Dec 5, 2017 | Blog | 0 comments

This Mercedes CLS was dropped off with us with lack of power/ limp home mode activated and engine management light on. The initial code scan brought up “2510-001 Check component Y77/1 (Boost pressure regulator). Positioner signals fault”

The component that the fault code is referring to is the electronic actuator that controls the variable vain turbo. After extensive testing on the actuator and position sensor it was conclusive that the component was faulty.

Obviously you can’t buy the electronic control side of the turbo separately so new turbo it is! Ouch!

New turbo fitted problem sorted and one happy customer.  Customers words “the car has never driven as well”
