At the moment you only seem to be able to get non waterproof covers for about £300. Or Brandrup do ones that match the current seats exactly for about £500. Both should have breakaway seams in them.i'll have to go down to the dealership and ask again, as i was told that VW hadn't released a airbag compatible seat cover yet, when i placed my order.
But neither is water (or in fact anything) proof.
I just wish they bring out the VW waterproof covers like we had on our T5.1 Cali!!
