Thanks, MBZ - Balance Shaft Repair

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.

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