Check valves and chain tensioner repair costs








Base 2013 E550 Timing chain tensioner ONLY
4Matic 2013 E550 Timing chain tensioner ONLY
It would be great to know the reasoning for such differences. For the V6 w/o turbo, $2400 is too much for the check valve+chain tensioner even at the dealer.
Here is a video of replacing the solenoid, which is trivial compared to the tensioner. The timing covers must be removed as well, and the driver side is usually a bit more difficult than the passenger side.
