The dreaded M272 Balance Shaft

MB C280 4MATIC 2006 (W203) 186,000km
Getting codes: Tool Snap-on solus ultra
1208/P0016-constant adjustment of intake camshaft of right cylinder bank in direction 'retarded'
1200/P0017-constant adjustment of exhaust camshaft of right cylinder bank in direction 'retarded'
car drives fine nothing really noticeable no vibrating, shaking, noise just check engine light.
maybe just the magnets? ordered them be here tom just..
could it be the balancer?
raced a infinity g35 yesterday usually beat them, but felt the car really lagging of the line was weird ?

I had the problem in 2006 c280. I have taken the engine apart you can see shaft is smooth where there should be a gear. I am selling the block cheap if anyone is interested. I ended up getting another engine off ebay and swapping them.

2007 R350. Thinking about purchasing this tomorrow. It has a transmission problem which I'm okay with but I don't want to get involved with a balance shaft issue.

Not too bad. Made in 1/2007 so it's past the balance shaft problem.

Your engine number as posted appears to be within the affected range, which goes up to 2729..30 468993-see the above link.
Get your codes read. The check engine light being on could be about any number of things.
i just had the codes pulled at Autozone
poo16 crankshaft position bank 1 sensor A
what is the most logical way to proceed in repair or options?
thanks again
You may want to take it into a dealer to check for a definitive answer there. Otherwise, you may be throwing parts at it that you don't need for the real fix.
If you are handy and want to do a check yourself, there is a YouTube video on this to see if things are lining up correctly.

if I fix it, is it worth the expense to fix? The car is very nice otherwise and fits me well.
thanks for your responses

thanks all

1. Repair it at an independence shop?
2. Drive it until there are major issues?
3 swap it out with a non-affected engine?
Im really at a loss of what to do.
Thanks again

As for what to do if it isn't, things aren't pretty. If you can't do it yourself, the cheapest would be at an independent mechanic. But make sure they know how to do it, someone also had a private shop do it and it didn't run quite right afterwards. You could keep driving it, but I think eventually it just won't start, you just have a few thousand miles before it stops completely, just the luck of the draw. As for replacing the engine, it's probably about the same cost, you'd have to get a 2007+ engine that didn't have the problem. But used engines are still in the $2000 range so it's probably about the same as taking it out and fixing it.
Also, what impact would changing the cam sensors have on the situation? Would that clear the code and resolve any of the concern?
Thanks
