Interesting I haven't seen this is it 8 injectors total then?@Arcam the 2.0 TFSI engine (EU engines only) as used in the S3 has an extra injector upstream of the inlet valves (4 extra in total) precisely to try and cure this issue, it's a very well known issue on FSI engines, esp on the V8's. They did look briefly at introducing this for the 2.5 5-cyl but there were too many packaging issues.
