I read somewhere that it can be done with the vin. WDDGF7HB7AF466623

Car is not in my possession yet, but a helpful member here suggested i look upmthe engine number to figure out which head bolts i would have. Thanks so much in advance.

Providing the VIN you can tell engine build date...?

Valvestud

Yes, provided it's a US car.

Feel free to respond with your VIN or PM me and I'll look it up on STAR TekInfo.

Make sure it's still under factory warranty (either new car, CPO or ELW) and you'll cover your bases. If it's out of warranty, a third party warranty probably isn't going to be sufficient if you encounter the head bolt issue. :\

thanks so much folks. looks like I have the old bolts unfortunately, but not a dealbreaker for me. I'm going to monitor my coolant for sure and knowing about the TSB is definitely a huge advantage already. Full original factory warranty until Aug 16 2014. Plus I'll likely extend.

If you don't intend to mod the car, buy the MBZ extended warranty when you purchase the car. The price is negotiable contrary to MBZ assertions.

I'm buying used and it's not from an MB dealership, so not sure if this is an option for me.

Wait 6-8 months until prices drop a little bit more and get a 2010 just for a piece of mind

The head bolt issue also includes some 2010 engines.

ddcha

has anyone attempted to guess what % of engines with the old bolts have had failures? And what does it take for a dealership to conduct the TSB work and replace the old bolts with the new? I know it may vary from dealer to dealer, but wondering what the best litmus test is to have them do the TSB work.

Only the early 2010
