this may be a sneeky way to get an oil change but i felt i really needed it since my i started getting 350 km instead of 500 or 450km on a full tank .. so a few weeks back when i went to the dealer for some small software probs i just thru in my lil plan and said that i also get an error sayin oil level too low .. they said they would look into .. so when i came to pick up the car i was told that all the probs were fixed accept we did not see anything wrong with the oil level sensor or anything ... a week later when i picked up the car i got an error saying active stearing is inactive so i rushed back and showed the servie manger i alos thru in the oil level prob ..
so i got my car back yest and all probs fixed and also a free oil change

 

I got a free oil/filter change a few years ago on a previous Carrera. The RMS went and they need to drain the oil to replace it. Not exactly the ideal way to get a freebie, though!

 

At the expense of having a AS inactive warning / problem pop up? FORGET IT!
