Hi all, Took my 2000 S3 to a local VAG specialist today as I had an amber oil sensor light come on. Turns out the oil level sensor has died so a new one needs to be fitted. When the diagnostics were plugged in it also threw up a dodgy N75 and they have suggested again a replacement having checked all the hoses. My question is where is the best place to buy these parts? I'm not after oem per say but a good quality part none the less.
