Hi All, I've heard on the grape vine that the above valve on my A3 1.8T is probably faulty and has been naff since the time it was born! I was also told that the original one (bosch i think) has been update recently because of its short life span (different make too) Can anybody shed any light on this? I didn't have the car from new so wouldn't no any better really! It a 97 P if thats any help. Cheers Jinx P.S. not looking to fit aftermarket one tho.
