wes68 Posted February 25, 2011 Report Share Posted February 25, 2011 Hi all,im hoping someone out there can help me.My 02 cabriolet has developed an intermittant missfire,very irritating! A friend of mine has done a vagcom sweep on it & came up with a couple of codes: 16684-random/multiple cylinder misfire detected (po300-001-upper limit exceeded-intermittant) & 16686-cylinder 2 misfire detected(po302-001-upper limit exceeded-intermittant) those were on the engine check.Another one came up on the auto hvac check & im curious if they are linked: 00819-high pressure sensor(g65) 07-10-signal too low-intermittant.Any help would be much appreciated.

Mook Posted February 25, 2011 Report Share Posted February 25, 2011 Welcome to Tyresmoke What engine is it? If it's a 1.8T it will almost definitely be one or more of the coil packs. Quick to replace and about £25 each. There's one per cylinder. Link to comment Share on other sites More sharing options...
