Hi people got a prob with an A2 1.6 fsi logging a misfire on cyl's 1,2 & 3 then another code of just misfire, codes are;

vw 16684 or p0300 misfire
vw 16685 or p0301 misfire cyl #1
vw 16686 or P0302 misfire cyl #2
vw 16687 or p0303 misfire cyl #3

no code for cyl#4!


all pencil coils & plugs replaced still getting codes present
all compressions are good no visable probs with wiring etc

basically the car drives well no lack of power and no misfire but malfunk light comes on and flashes all these codes are then present but car has not missed a beat.

anyone heard of any software updates or wiring/ecu issues?

cheers jb
