Evening all.
so after 8 months of wondeful problem free motoring in my D5 i got my forst problem tonight.
112k miles and I just changed the oil this last Saturday. Then tonight, driving up the motorway to visit my partner in hospital and I get "Engine System service required".
Luckily the car still ran (well enough to get me to the hospital).
I have about a 30 miles to drive home. Then tomorrow i have a 200 mile round trip to complete tomorrow! :/

Is this message just because the On Board Computer thinks an oil service is due (as i didnt tell the car id changed the oil)? If so how do i reset this? Or for future, how do i tell the car that ive serviced it?

Or is it likely to be something more serious??
