Anyway the car should work also in D-mode so that's not the official solution but might help with high oil consumption. My engine checked twice and nothing repaired or they just don't tell me. Oil usage measured to 0,3 litres per 1 000 km.
I don't think that has anything to do with it because when the supercharger is not being used, it switches off. in fact, unless you are using something like 30%+ throttle application, it won't even engage from a standstill so I think it is more likely just coincidence that your engine has probably just "settled down" with it's consumption. Did you happen to change oil brands in this time?

NO surprise really that the miracle pipe has not done it's thing, so I will be looking at another means as talking to an engineer of another major car company that has suffered major oil consumption issues in their v8 turbo diesels, there can be a lot of masking of the true oil consumption just by checking the dipstick. To be honest I didn't fully understand what he was saying but my basic chemistry understanding said that all that is in oil after 10,000+kms aint just oil that is making up the volume....
