Title: Can faulty PCV lead to Exhaust System warning light?
Post by: andrewparker on November 24, 2011, 09:07:50 am

Hi guys, as you might know I've been having a number of issues with my car, in particular the almost constant presence of the exhaust system warning light.

So far I have changed the DV, N80 Solenoid Valve and the EVAP Canister. However in the past week I have been experiencing a lumpy idle and over-revving at idle. I understand this is most probably due to a faulty PCV.

My question is, is it possible that this could result in the exhaust system warning light?

Dont think the exhaust light normally comes on does it?

I've been looking into the BSH PCV fix kit for mine, fit and never have to think about PCV troubles again...
