There are no error codes when I do the read and the yellow engine warning light extinguishes as soon as the engine starts. I only see the situation that Pscan reports “?” when reading live data with the engine running. Tick over is smooth and it accelerates strongly and without misfires. Is it just that Pscan is unable to obtain a valid status from the pack or ECU? I think a coil pack replacement will be done soon .
