MK5 GTI 2.0 TFSI Misfire Advise..

[Jayy]

Hi Guys,

Some advise please..

VCDS brings up;
000768 Random/Multiple Misfire Detected P0300 001
000771 Cylinder 3 P0303 001 Misfire Detected
008801 Boost Pressure Control Valve N249 P2261 Mechanical Malfunction

Basically got a low down misfire, sounds quite rough, however at higher speed, and higher gears it seems to go away, and also in the higher rev range.

HPFP has been changed, along with the sensor, and the cam follower, and coil packs have been tested and are fine, any advise on where to go next?

I can't find the log, or block to check the injectors on VCDS, anyone help me on where that is?

Changed the spark plugs??
