misfire under light load

[200q 20v]

Interesting. The link shows BOSCH 09268 which 5th cylinder wire was
way too short many years ago that is why I had to get BREMI. This set
is designed for 7A engine. I had a lengthy conversation with BOSCH
tech about it. They don't make separate set for 3B. May be that
explains why coil wire was short for  you.
