Repair of N57 timing chain


Recommended Posts

Good evening,

Is there anyone who can provide the cost of repairing the timing chain on a 2014 330D GT? Is it prudent to repair the crankshaft bearings in conjunction with the oil pump?


Thank you in advance.

It is merely a direct chain replacement; personally, I would not replace the crank bearings if there are no issues. In my view, rectifying something that is not broken may lead to complications. Despite the installation of new bearings, there is no assurance that they will not fail within six months.
Performing regular oil changes and refraining from starting the engine immediately after an oil change, allowing it to crank for 10 seconds, are the primary measures to mitigate potential hazards.


The cost of chain replacement varies according on the location you are considering. What is your location?

You will not encounter a more competitive pricing or more upfront, honest fitter; I wish he resided nearby, as I would take my vehicles there.
