[notorious]

Have no more ideas about initial problem -- sorry.

I was reviewing PCV valve story as I'm going to change my PCV valve soon.

Opening ETKA revealed that two hose clips N 104 180 01 that require special tool where superceded with 'classic' hose clips with a bolt part number N 905 618 01 in cars with chassis number after F 4D-3-006 001. These are cars manufactured in August and September 2002, two months before D2s were removed from production -- 'final editions' perhaps.

Interestingly, rubber pipes and PCV valve itself where were left the same the moment they changed the hose clips, which proves that 'classic' hose clips will work just fine with older cars.

Although I have the special hose clip tool I'll be ordering classic N 905 618 01 hose clips with bolts as they are simply easier to work with.
