Code 17763, 17772 and 17775

Okey, I have some codes which I don't understand which that keeps coming back.



I tired to remove the coils and plugs yesterday to see if everything was okey, first thing I saw was all the plugs had some carbon fouling.



This can indicate wrong mixture so I hooked the A/F meter to bank one and two. The mixture was around 14,7/15:1 on idle which should not be a problem? Maybe a little to lean but nothing to worry about I guess.

Vagcom dont show anything abnormal either.



I also saw that I have abit carbon buildup on the pistons after just idling the far for a total of 60 min maybe.



After checking all the connections to each coil, I swapped the coils around and installed new plugs bot got the same coeds, only this time the Cylinder 5 didnt have the "intermittent" word in the code.

Any ideas? Maybe I just need some load on the engine to burn of the carbon on the pistons?

btw, I have installed the 2.0TSFI coils on my car.

The car is running fine, so all the coils are working.

The codes are:
17763 - Cylinder 1 Ignition Circuit: Open Circuit
17772 - Cylinder 4 Ignition Circuit: Open Circuit
17775 - Cylinder 5 Ignition Circuit: Open Circuit

The codes suggest you have wiring issues and considering you just did the 2.0 coils, I would double check all your connections. Once you get this sorted the plugs should self clean after driving around a bit. Are your plugs stock heat range?

Edit: also no one really checks this section; its always best just to post in the main section of this forum.
