    Hello,
    I was logging some runs and had the misfire counter on for each cylinder. On the first run the log showed a 2 under the misfire counter for cylinder 5 until about 3500 rpm, then the misfire counter has 0 for the rest of that run and the following run. When I savd the log i got a seperate log that was a txt file.

    I am new to the VCDS VagCom system and do not know what to make of the txt files above. Is the misfire being subdued by the ecu to prevent damage and thatz is why the counter shows 0 at the point where the txt file shows disabled misfire recognition?

    I also logged boost pressure and N75 Boost Pressure control because i think Ihave a wastegate issue. What value should i see for boost pressure control(group 114) and how close should the specified boost pressure be to the actual boost pressure?
