xyber 1 Posted July 1, 2010 Report Share Posted July 1, 2010 They're shite mate, I went through several, make sure you get a genuine vw one, only about £12Mine used to startup and idle at nearly 2k rpm and usually stank of fuel. A dodgy MAF also caused this fault once but didn't even show any codes Link to post Share on other sites
