The best M276.x VVT replacement video + welding of misaligned camshaft tone wheel




It has to wear out someday and before the chain.
Like our dampers/shock absorber, it will wear out and no need for it to leak. If the nitrogen gas chamber inside the damper tube is breached, the damper will behave funny and you do not see any leak.

oh yes my shocks are done i ordered new but will not mount them until i fix the rattle.. i can't believe how weak are the shocks (so many ppl complain from them)

also they were not in stock for a year in MB dealer which was shock for me... (im talking specifically for the ones which have the option to make them stiff from the button console)




My friend's M271.860 W204 C200 has super loud knock at 70,000KM.
Again it depends on how the car is driven and average speed, thus engine hours can be counted.
In Jakarta my city, my average speed is 21KM/H, thus is I do 100,000KM, that is 4,761 hours of operation.
Traffic jam, stop and go driving is really bad for everything mechanical and more so if ambient temperature is 30C and up all year round.
Variable valve timing does its variable when the RPM changes. Good open highway driving is like a nice fixed RPM and cool wind cooling everything, the engine so relaxed a such load... engine live longer.
My front SACHS damper, can't even bounce up on it own when I tested it while replacing with Bilstein B4, it was less than 25,000KM but like 5 years old back then.

B4 are really difficult to find or at least last year was.. is your B4 with damping or normal b4

btw related to the topic if failed VVT should we check only that camshaft for misalignment or all 4 we should check

P.S. after replacement of VVT is it needed some adaptation reset or nothing required apart of mechanically repair

There is adaptation method in Xentry if I remember right. It will adapt itself overtime too I believe.
Sorry me VVT is still OK.
