I have 76k miles on a 2006.5 GTI manual. I had the coil packs replaced around 50K under the tsb. The fuel filter was replaced around 60K and the cam follower around the same time. I just replaced the spark plugs and have swapped the coil packs between all of the cylinders but hasn't fixed the issue. When I scan with the vag com it is always Cylinder 4 misfire when the check engine light comes on solid. I just put in a can of BG 44K in my gas as a fuel cleaner to try and clean the injectors. The car idles rough but doesn't stumble at all when driving. My next step is paying for someone to clean the fuel system but the quotes are more than just buying a new injector. I need help guys cause this car is driving me nuts. Not sure where to go from here.
