Timing chain tensioner
Will the dealership or MB pay for this? If not, anyone know how much (ballpark) it costs to get fixed?
Brought my 2013 ML350 to Dealer with this information for this problem. They changed out chain tensioners. Install check valves etc. Hope this helps someone.
If you have to do the repair it takes about 7-8 hours to complete the work plus the cost of parts.
Also have heard what sounds like a worn serpantine belt for about 30-120 seconds after a cold start up, then it just stops and engine is as quiet as you'd expect from there on out. No idea if the two are related and what is or is not normal for the engine.
The short rattle seems to be a known issue on engines before 2014 sometime...
It was a warranty fix back then.
My ML runs great and neither issue appear to be something that is mechanically hurting the engine, but both are in the "unexpected" column...especially with such low mileage.

tsb is a known mfg defect. If I had known it sooner. Could have brought the car in and they could have fixed the defective bracket before the hose rubbed through.
So yes if you know of a defective part you don’t wait until it breaks to replace it.
i believe a recall is different as it pertains to safety issues

i would disagree that is exactly what a tsb is for. I have a Acura TSX way out of warranty power steering hose rubbed and was leaking. Found tsb on this problem and Acura fixed at no cost.
