I just picked up my car a few days ago and immediately noticed a light rough idle. I took her in today and they checked her up fully, no faults.
The service advisor tells me it's due to bad fuel and added an additive, asked me to drive her a little more and this should go away.
This isn't my first performance sedan, so I know something is not normal here. The car has 40 miles on it since driving her out of the showroom.
My E60 M5 and 997 PDK didn't have this issue. I know the 997 was DFI and my E60 was not. But this is the first time I see this on a brand spanking new car.
Very odd. It is possible and even most likely you have bad fuel. If you dont mind me what octane are you running? What type of additive did they put in and how much?
