Hi all my car has been running like s**t lately, really lumpy and juddering, the juddering is intermittent though, so I checked the coil pack and it's got good spark from numbers 1,3,6 and 5 but 2 and 4 is only sparking a little, not as much as the others, so my question is
1. Would this cause the car to run like it is and
2. The part no I have is 078 905 101c, does it matter if the part I buy has an A at the end instead of a c,
The cars a 2.6 v6 quattro on a p plate. Thanks for any replies

I think the 2.6 has 3 coils, running wasted spark, so if one failed it would make sense that two cylinders would have a weak spark.

Theres a "C" part on ebay.

Ok thanks aragorn so I take it the "c" part would fit it doesn't matter that mine has an "a" at the end

Try swapping the coil to see if the fault moves cylinders, then you know you deffo need one
