Hans has worked on some of my cars since 1982 when they had something wrong that I couldn't fix.


So should I replace the CPS on my ML due to the mileage or the age?

Edited:

Alldata says:
"NOTE: If the crankshaft position sensor (L5) was replaced, a re-initialization must be carried out with STAR DIAGNOSIS in the menu item control module adaptations."

Is was alldata says accurate? or is the re-initialzation only necessary if the one you are replacing is defective and was in use when it stopped working. In other words if you replace a functioning CPS due to age, mileage or whatever, no re-initialzation is necessary.
