I own a 8l 1.8t a3.... Currently has on it a nasty dump valve which was on it when I bought it. I know these are cause for concern so I'm trying to buy an oem one. My a3 is a 2001 model, so do all of the diverter valves off the 1.8t engines fit? I've come across 2 different part numbers on eBay. Does this matter? Is this part number correct? '06A145710' thankyou.
