I am aware of the noted problem and the TSB. I assume this work is a must do?

Has anyone had this work performed either by an indy or Benz dealer? Ball park pricing through an Indy?


Thanks for any feedback.

 

Roughly $3k at an indy is about right including revised tappets.

 

Yeah, $3-4K with an indy. Preferably an off-duty MB dealer mechanic (IMO) A dealer is prolly double that , at least.

I don't think it is as big a problem as the internet made it out to be, the number of cars that had actual failures is fairly low...I've had my M156 for 5 years with zero issues. I too was worried prior to purchase, but all that sleep was lost for nuttin'.

 

So are the Black Series cars in the TSB so should not MBUSA pick up the tab i am looking into a BS so should i consider this a must do and lower my offer if car has not had this fix

 

I don't believe they will 'pick up the tab'....they 'might' help you out if there is a failure, but only if there is a failure...preemptive replacement will not be covered I was told from my local dealer.
