Hello everyone, I have swapped plugs/ coilpacks no1 and 4 to cylinders 2 and 3 then misfire disappears but comes back after a 20 min test drive to cylinders 3 and 2,done compression test,cylinder 2 slightly higher than any cylinder at 210 psi,remaining cylinders average around 185 psi,since I don't have documented compression figures,I'm pretty groping in the dark,I'm suspecting the coilpack wiring harness but I don't have testing procedures or WD,I'd be grateful if someone can open my eyes on this and if the other fault codes are a contributing factor

In addition to Uwe's fine suggestion...... :rolleyes:

That and the G294 being a short to + bothers me....

Get ERWIN and WD and trace the bus and all components with a DTC to see what is a shared track.

This is FSI engine right? If you have original coil pack, I would guess that's the reason for the problems. They are prone to go at some point on these engines.

Or another option, look here : http://www.vwaudiforum.co.uk/forum/showthread.php/74386-A2-1-6-fsi-misfire!!!!

Disconnect the ECU for 2 hours to completely reset it, seems that ECU gets "full" on it's adaptation value table and does not adjust the ignition timing correctly.

Hello Jack,client says this particular injector has been replaced, there's this intermittent sharp sound of coil pack leaking current to ground even after swapping coilpacks which puzzles me,

Thanks Downtime,Yes,it is FSI,3 coilpacks made in turkey,1 in Italy,they look original,I will try to get different coils to fit and try

What about water ingress inside ECU for FOD?

Two shorts .....very uncommon.......water common!

Hello Jack,I think downloading pdfs from erwin is a bit tricky,so i took my time and found out that the wiring harness to fuel injectors was misrouted and passed too close to EGR steel tube near coolant flange,and injector No2 wires insulation was slowly being roasted thereby exposing them to contact ground on EGR tube, I then properly rerouted the harness after applying good insulation.The misfire disappeared for good,we test drove for close to 100kms,it hasn't come back,but new error codes have come up in this autoscan,i also found one broken brake boost sensor wire,soldered back in place,no more problem with it
