blow-off problem

cre · 01-04-2012, 04:32 AM

Code 52 is a knock sensor circuit malfunction and will cause severe operational problems. Code 51 indicates that either the A/C is in operation or the IDL switch in the TPS is open and is not a critical code although you should make sure that the error was indeed because the A/C was on or the throttle was open.

FYI - you can not set the timing with any codes present.

If the BOV is remaining open then you either have the spring too loose, the vacuum lines are not properly routed or the BOV is damaged. With a recirculating setup it isn't an issue at all as long as it's closed when boosting... one more win for recirculating.

sell the bov and just get a simple bosh bpv........thats wat i have, its loud, sounds epic, and it works amazing. the only thing u have to do is stretch the hoses over the bosh ends because its bigger then normal hoses. and there also cheap. idk if that's the Bosch 110 or the 102 in the pic but the Bosch 110 has a stiffer spring, which is good because the 102 has been known to leak due to a weak spring, but i know a guy who is boosting 19psi on his mk3 with a Bosch 110 and works great. Just a thought i guess, good luck anyways!

Does blow-off must be on a right pressure to give best results?
