clk defective balance shaft and/or balance shaft sprocket.

What engine serial number or VIN should I look for? I have a clk350 2007 model. The car has 125k on it and seemingly perfect dealer records.

I am worried the engine part will go at anytime, but I also hear it goes at 60k to 100k. Since it requires engine removal, I am very interested to know if I have one of these repair time bombs on my hands. So far everything works in this car.

Thank you in advance!!!!!!

Silver Surfer,

What is the VIN of your car? That is needed to look up the engine number. I have just replaced the balanced shaft in mine.

Consider all 2006 and 2007 models as candidates for the balance shaft repair. Officially, Mercedes issued a TSB (technical service bulletin OR The Sucker Buys) that says all 2006's and some 2007's. However, since there are some '08's showing up with the problem, I would say it's possible with all but most likely with all 06's and early 2007's.

Now that I've said that, I think it's unlikely you will have the problem since the issue occurred on most vehicles before your mileage mark.

2005 S430 4Matic 'Morton' W220.183 • 722.671 Rest in Peace
