Hi,

I'm brand new in this Forum, so let's make a small introduction.

I own a VW Passat since 2002 with any special problems.

Anyway in a period of the last 11 months, i had to replace the CCM twice.

The VW dealers told me that there was water entering in.

Questions:

Shouldn't be the CCM waterproof, mainly during the warranty period?

Do you know any EN or ISO specifications about it in which we can proof these facts?

I hope you can help me.

Best regards
