Hi sir. Just an update, I rebuilt my engine as the oil consumption got pretty bad. My workshop replaced the timing chains too for vanos, but did not replace the vanos sprockets. I no longer fault codes but I still have a mild version of this where I gently throttle, the rpm goes down before going up, and drops back down to about 500rpm before going back to idle rpm at around 700. This happens in neutral, d1 and reverse. So just letting you know, might be the timing chain. But I did not get this issue fully resolved. Power also feels down for some reason. I’m on stock map, no mods.
