jimboyoung Posted April 5, 2009 Report Share Posted April 5, 2009 Just had MIL triggered on my 2003 S4 and was wondering if anyone could shed any light on it. I've plugged in my VAG-COM (release 409.1) and the fault is shown as 16684-P0300-001 Random/Multiple cylinder misfire detected. Is VAGCOM unable to determine multiple misfires on various cylinders? or is there a way to identify the coil in question? Does the 001 prefix at the end of the code indentify the cylinder? I've changed the one on cylinder 5 recently too but this fault was shown as only that cylinder. I know that VW/Audi and even Bentley have common faults with coil on plug units. Any help would be gratefully received. Link to comment Share on other sites More sharing options...
