Unfortunately I can not post it.
Not much change. It just states if the solenoid is sticking replace it, and if the O-ring is leaking replace only that. There is mention of the updated solenoid. It also removes the info about 1200 and 1208 as they have been incorporated to a separate LI.

I do have a question, though. In looking at the TSB, it uses two-letter model indicator codes that I am not at all familiar with. They obviously indicate the possible chassis and engine combinations. Is there a list of those? I added my 40+/- hours based on assuming which code was my CLK550 cabriolet.

If you totaled up all the labor operation codes in the bulletin then you would end up with about 40 something hours, however not all those opcodes apply to your vehicle. MBUSA has since employed an automated system to total up labor for bulletins via the model indicator, or two character code. There is a listing on startek info of model indicators. The exact time for your car which I totaled up was 18 and change hours. The dealer can sometimes fudge the numbers and get up to about 30 from warranty, however that time is not legit.

2007 GL450, 2003 BMW 325i
I know this is an old thread but I thought I'd ask anyway cause it came up in my search. My 07 GL450 with 89k miles has thrown one and only one of the codes mentioned above (P0025). I've read it's a simple change out of the solenoid. There is no oil leaking from the solenoid so I was planning on just changing it out. I know I have the engine build with the potential camshaft issues but throwing this one code tells me that it could only be the sensor right? Or am I just wishful thinking?

P0016 and P0017 are the balance shaft failure symptoms. P0025 iis just a bad solenoid (a.k.a. "cam magnet"), and that's an easy (even DIY) and cheap (about $100 ion parts for all four) repair.

Thanks for the info! If any tips on DIY, please let me know!

You can get all four solenoids for about $100 from mboemparts.com. THree of them are easy - unplug the wiring harness, remove three Torx bolts, gently pry to remove, then replace. Once of them sits behind the oil cooler (I think - i know it does on the V8, I guess the V6 is the same). This means draining a gallon of coolant, and removing a few bolts for the oil cooler. Technically, it would need a new gasket, but I had no issues on my 550 when I did it.

DTC 1208 is not always about Balance shaft!
@MBtech1098 @Rudeney @Glyn M Ruck : I had 1208/1200 but can't find the crank sensor location to do an oscilloscope yet. However, I was able to check pulse wheel locations behind Intakes on both Bank 1 and 2 and found them to be perfect centered. Based on M272 where intake drive exhaust, is it enough to say that I don't have balance shaft worn nor timing chain stretched--otherwise, pulse wheel won't be in perfect location?
I said I had 1208 but not anymore after replacing not only Solenoids but also Hall sensor and Wiring harness to eliminate all potential causes--and still much cheaper than open up valve covers. Now I am back to 1200 only due to pulse wheel on Exhaust/Bank 1 has shifted a bit. Will take care later.
In the meantime, while working on those magnets and hall sensors, I came across this hose (two yellow rings on each end) that connect these devices. Just curious what are those devices being connected by that hose? Thank you.
