A couple of months ago I took delivery of a pre-owned E220 Cdi (W211).

After delivery, I received the service history, which was not up-to-date. The service booklet was returned to the dealer, who assured me that a service had been carried out pre-delivery. The booklet was then returned to me with a new stamp.

I've just checked the car's computer and discover that a service will be due just 6,000 after I acquired it. I know that service intervals are variable, and depend on journey types and driving styles; but the car has been driven moderately, mainly on extra urban journeys.

I'm in some doubt as to whether a service was actually carried out and I would be very grateful for answers to two questions:

1. Does 6,000 miles between services seem short?
2. Is it possible to tell when the ASSYST service indicator was last re-reset?
