Hello, my name is George, I'm from Moldova, sorry for my bad English, I need your help, I own a European model car "Skoda Octavia", production year 2014, engine 1.8 TFSI GEN3, code "CJSB", AWD, gearbox DSG DQ-250, I can't find the solution to my problem for almost a year. The problem appears mostly in the "Sport" or "Tronic" driving style, accelerating slowly, most often between 3000-4000 RPM, the car starts to vibrate and loses power, after restart ignition check engine disappears until the following conditions are repeated, fixing the following errors:
P030300 Cyl.3 Misfire Detected
P030200 Cyl.2 Misfire Detected
Sometimes these are fixed :
P039B00 Cylinder 1 Pressure Too High
P03B900 Cylinder 4 Pressure Too High
P233800 Cylinder #3 Above Knock Threshold
P233900 Cylinder #4 Above Knock Threshold.
How could I understand the error with too high pressure? physically it is not a pressure sensor in the cylinders. Most often is fixed misfire on cyl. 2 & 3. I changed almost half of this engine but without success. I went to the dealer with this problem, but this did not give anything positive result, I even replaced the cylinder head and engine wiring harness with their recommendation. What I have already discovered by testing the car in different driving styles, "short term adaptation" is mostly has a negative value as well as "long term adaptation", and close to the moment when it fixes misfire these values exceed -26 % on "short & long term adaptation" and a different engine sound is heard. I replaced new magnets N205 & N318 for camshaft control valve, all the injectors TSI + MPI, the high pressure pump, all exhaust valve lift and many more parts but is the same issue.
The only method I discovered to make this problem disappear is to unplug connector from magnet camshaft control valve (N205 or N318). I also checked the oil pressure, it is fine in both working stages, from what I understand this problem can be caused by timing issue, I replaced the distribution chain same result. I recorded my screen values if this is needed I can upload. Help me please to solve this problem, I appreciate every answer, thanks.

@Tom Wolfe from "Positive Lead Diagnostics" maybe you can help me, given your experience on VAG model cars.
