Hello,
It looks like my dual mass flywheel failed. I am gearing up for an eventual replacement of the rear main seal.

I have called the dealer and gave my VIN number. My car was made Dec 05.
I then inquired about the rear main seal. They said that they have two p/n listed one thicker (12mm) and one narrower (8mm). He said that they use the narrower one.
He seemed to imply that they now use the narrower one even if say I would have my car done by them.

I have looked this up and indeed from Jan 09 they used the narrower one.
Besides the width, the newer one looks like a normal seal in the sense that it does not have the two grooves to accomodate for the crankcase seams.
The procedure asks for two component Loctite seal (a primer and a seal in a syringe). I am guessing this is for the pre 09 seal with grooves.
I tend to go with the post 09 seal and smear some permatex red where I have the crankcase seams.

I am also assuming for the seal without the grooves you wouldnt have where to inject the sealant.

It would be cool if we could find out if that crankcase seam is any different in between the post 09 cars and pre 09 ones.

Thanks so much for any clarification.
