[QUOTE=M5 London;20316188]1) Which dealer are you using ?
2) Have they declined to carry out an official oil consumption test (or something similar to this) ? I presume not.
3) What is the exact brand / type of oil are you refilling with ? Does it always request 1 Litre to be added ?
If you drive hard then let the car slow down in gear and then floor the throttle and accelerate hard and you see quite a bit of smoke out the back, or someone following can confirm, then it could be piston ring issues allowing excessive 'blow by'. It could also indicate a faulty / clogged crankcase ventilation system causing crank case gases to be sucked back into inlet manifold and burning off rather than returning to the sump. I think the S63TU set up is like this....
Yes its always asking for a litre to be added, the message pops up around 300-350 miles, however since the oil replacement it hasn't done so, but never speak so soon!!
The car was bought on a HP deal with 50% deposit towards the car.
