B1 service and 18700 miles
dashboard is telling me that I have ten days left for service I'm wondering if I can go at least another 500 miles before I take it in. Which might take maybe one more month to reach. Also how much am I expecting to pay for this service ?
You can go 500 miles without a problem and I'm 99.9% sure it won't affect your lease assuming you do it at 20,000 miles +/- 2,000 miles.
Also you can reset the service warning yourself.
