Hi , can anyone tell me the part number for the rubber seal that goes between the windscreen washer motor and the washer bottle please ?

2017 superb 1.6 diesel.

Thanks

I suspect you are refering to the rubbe o-ring like thing, look in the diagram here perhaps numers 8 or 12

If you cannot get it from the dealer, perhaps a well-supplied auto store can get you a similar size o-ring (see they are listed in size in the diagram).

Good luck!
