i have been trying to locate the leak in the rear of my Octavia and have noticed the rear wiper motor shaft sealing ring in the tailgate is leaking. can you just buy the part or do you havr to buy a whole new wiper motor

I bought a new one - about £70 iirc they can be disassembled and cleaned up but they dont last.

Thanks for that looks like a whole new motor just to get the sealing ring
