Bindi - i read that in the other thread thanks for confirmation

So to continue the story, armed with the above info i thought i’d pick on one coil and go from there

Repinned 2 - 4 to match what bindi confirmed above - grounded pin 4 to coilpack mounting point for testing purposes - still threw ‘open circuit’ code

Next i grounded pin 4 to inlet - same code

Then i ran pin 4 to bulkhead ground behind header tank - same code

I have a few old tfsi coils laying around so tried that, grounded to valve cover - no code



Next for testing repinned 2 - 4 with now pin 2 grounded to valve cover - no code

Dropped a new uprated rs6 coil in left wiring as above - threw a code

Tried another cylinder with tfsi coil and left wiring as was - no code

Also tried a 1.8t pencil coil as above - no code

I guess these ‘uprated’ coils have different inners that the ecu doesn’t like
So the solution is to ditch the fancy coils ?
