Dear all,
1.8T ARY Engine with stage 1 map.
Experiencing a feeling of loss of power. Have full VCDS and no fault codes logged at all. Lambda (add) 0.4% and (multi) -3.1%.
Oil changed 2,000 miles ago.
New plugs (BKRE7 gap 0.30)
2.0L Coil Packs
New fuel filter
Use RON 99 or 98 fuel.
New N75
New thermostat
New CTS
Replacement Bosch MAF.
Experiencing a loss of overall power and juddering when accelerating. Better when cold, but still not great. Have completed a pressure test and no obvious leaks. Any advice would be appreciated. Have scanned all the forums for months and no one solution or symptom fits my issue.
Attached is a picture of the VCDS that I pulled recently. Knock as high as 20v on cyl 2 6000rpm.
Thank in advance
