Thank you ! You saved me a year later I still had the lock pin and spring when I took the heads off . I had no idea where that piece went , I pulled off the sprockets and the right side intake gear sprocket included and noticed that lock pin sitting inside near the valve springs and hydraulic lifters , I was baffled where it went since I never opened up the gear . Thank goodness for a year later finding this detailed video and now will not have extra parts leftover from that job a year ago !!!

By far the best video on youtube on these. A few questions to better understand the system: 1. Is this an 'either on or off' system or does it adjust the timing in between the cam phaser range? 2. The torsion spring in the adjuster - is its job to bring back the adjuster to the point where the plunger locks? Does this happen when the oil pressure is reduced due to the solenoid not pushing the cam phaser oil valve? 3. Does the oil pressure from the valve in the cam phaser also unlock the pin?

9:00 So when testing to ensure it correctly locks, youre rotating the crank counter clockwise to engage the pin, then wrenching it clockwise to see if the pin snaps out of place? Im at 200k miles and am looking at this on my c230k. Thanks!

Do you have the process for the M274 engine 2014 E200. There are no alignment marks for the gear hub align to camshaft,but also do you need to load the chain for the gears ? Appreciate any help. This motor has changed from P0016 to now P0341 this is a click when manually turning the motor over by hand. Parts that were replaced timing chain and tensioner,both gear hubs (look different to your video) all genuine Merc.

Great video, I'd buy you a pint if you were local. Early M276 engines secondary chain tensioners don’t receive adequate oil flow on start up. Mercedes did update some parts Q. What would you say leads to failure? Late oil changes or assembly issue? I ask because the 2015 C300 and C400 Mercedes M276 engine still seems to have cam related failures from 60 to 71K miles.

Hi Gerard. Quick question. We have just changed our camshaft adjusters, timing chain and tensioner on our 2012 Mercedes-Benz C200, M271. There was a small pin that we not sure if it came out somewhere or were it belongs. Is there a possibility this came out the camshaft adjuster? I can't see one like it in your video.

Awesome. Thanks! I was looking for clues on how might lock these on my bmw n73... Looks like I can just swap the spring loaded locking pin for a longer non-spring loaded pin, unplug the valve and be done with it. Right? I'm using an 03 n73 V12 in an old jeep Cherokee overlander project, so I'm stripping/deleting all the electronics, and adapting carburetors, and HEI distributors for ignition. Thanks again!

It would appear that the VVT will allow for about 2 teeth of timing adjustment, 44 teeth on the cam gear so a bit more than 8 degrees per tooth and a bit more than 16 degrees for two teeth, times 2 or a bit more than 32 degrees total advanced timing for 2 crankshaft rotations or 1 firing event or 4 strokes of the engine or 720 degrees of crank rotation. The capability for this system will be viewable on a scope or live scan data if given in that format. The DTC did not give a specific value to set the trouble code which would be in the service data. I would only guess at a value greater than 8ish degrees to set a code??? Thanks so much for the video and tutorial, now I can see the locking pin does not have to be broken in half or jammed in or out, this one is simply slipping out of the locking hole and making plenty of noise.

@Gerard Burke: nice video to explain little known topic. My W204/M272 engine is a bit more complex. Currently I have DTC 1208 as intake cam retarded. What’ve I noticed is that intake cam is supposedly fluctuate between 4 ADTC to 36 BDTC. In my case, it goes even to 36.2-36.6 which simply means timing is off, chain is stretched or sprocket worn? But what’s most interesting is: once it reaches 36.6 (rpm=3500) or 36.2 (rpm=2500) then it’s “locked up” (shows constant instead of fluctuation); what’s happened there? Do you have any idea, answer? Appreciate your input!

This is the same observance i have with my 2008 m272 3.5. Trying to figure out why its doin this as well. Is it the oil control valve or the cam phaser gear on right side intake. Dont know but sooner or later i think i may have an expensive fix. Dont think its the balance shaft though as mine is out of the affected serial number range. Let me know if you make any headway.
