dragon 0 Posted March 27, 2014 Hi just wondering if anyone who has one of these fitted had the same problem after fitting it . I'm running a CDA and the car was running great until I fitted the Bonrath , now it idles really badly and throwing up fault codes 00533 & 00553 both maf / idle speed related . Any reason why just changing the upper intake pipe would cause this cheers Quote Share this post Link to post Share on other sites
