Had my 2008 TDV8 around 3 months it was serviced just before I bought it, I noticed the other day on start up it said service 19 and a small clock, today the same thing but 17, does this mean 17 days? Can't seem to find anything in the book or on here about the service clock countdown, looks like the service clock needs a reset as it's only done 1300 miles since the last service.
