Hello Everyone,

Long time no see!

This spring break, next week for me, I plan to drive my car all week long! I miss it so much...

But... it seems that my car has developed a leak at the neck of the expansion tank.

I am going to replace the cap first, it is aged and is probably a good prevention item to replace.

Now, my problem is... Which cap do I get? a 1.2 bar one or the 1.4 bar one?
My car is a 1989 300E M103

Thank You
