what are the functions of B7 service on an S Class
Mercedes labels services in letters because their computers monitor how the car is driven and adjust intervals accordingly. A little old lady might have the "A" service at 7,000 miles, where a maniac might see 4,000 miles. "B" is the second service and the 7 refers to 7,000 miles. See a Mercedes approved mechanic.
