I've recently ordered a N75 boost controller valve as I've been having problems following a remap. (see post boost problems-follwing remap) I have a J valve on at present and wish to go back to the original. I ordered the original C valve part no 034906283C. ie. I just swapped the J for C (I've lost the old one). The part came today and is nothing like the original which was black with 3 pipes (1 longer). The one I have been given is round much bigger, gold metal and only has 2 pipes. Could someone confirm that the C type valve part number is 034906383C for a S3? If not what is it?
