Mapping these 2.0T engine really show up weak plugs.
As some of you may know , at the JKM RR day my car was showing a missfire on cylinder 3.
This morning I went back to JKM for a service and for a set of these plugs to be fitted. Hey presto no more misfire!!! The car feels so much smoother and pulls so much better.
Unbelievably VW suggest a change of plugs every 40000 miles which is a joke. On any car , especialy a remapped car , acording to JKM it should be every 20000 miles. Lesson learned...
