intermittent harsh misfire A4B5.5 1.8TQ

[swarz]

Hi,
My A4 has a really harsh misfire under load sometimes, other times it accelerates smoothly.
Could it be a boost leak, ignition failure, fuel starvation?
I have scanned it on a obdeleven, no codes.

Any ideas?

Run measured value blocks for missfire counter cylinder 1, 2, 3, 4 and go from there, find which cylinder logs a missfire..
