Can anyone find these part numbers for me please? My S8 is booked in for a timing belt etc and I thought I’d get these done while the front of the car is off. Thanks.

The headlight washer pump is 3B7955681. Febi do one. You also need a new connector which is 1J0 973 722, which Febi also make, and its prudent to fit a new seal at the same time which is 431955465A.

I’m wondering if, as I’m replacing the headlight washer pump (plus seals and connector) and the viscous fan coupling/clutch, should I also replace the screen washer pump (and seals and connector) as a precaution? If so, can you gurus let me have part numbers again?

I bought one as mine had failed.

Thanks Paul. Did that part include seals?
