Some scrote has nicked my rear wiper blade! Can anyone give me the part number for the replacement. Or a link to where I can buy one. Several searches come back as Bosch H772 is correct for both 8P1 and 8P2 but I'm not so sure. I also found VAG part number "8P2 955 425 H" but that doesn't really return anything definitive when searching online. eBay is rubbish as people don't seem to differentiate between front and rear blades! Thanks.
