S150 i.e. Originally from Germany.
I am in the middle of a grand tour of Britain, and would appreciate advice before getting recovered back home too soon.
Scoot has slight hesitation, like a misfire but then runs OK until it properly stops running, coming to a halt like the power has been switched off.
The spark plug has been replaced (the old one was in bad shape despite only being 5,000 km old). Sadly, the problem persists so it didn't turn out to be an easy win.
Any other things to try ? (it's an issue even on a full tank of fuel). Does the s150 have a fuel pump?
I should confess to a screw up prior to the trip. After a pre-trip service, I mustn't have screwed in the oil filler dipstick, and figure lost it on a shake-down run. It was about 8 miles and the low oil lamp came on 1/2 mile from home. The spray of ejected oil did an impressive job of getting a whole heap of places!

PS. In the morning, I will check the air filter which may have too much extra oil to be healthy, in case it's stopping air flow after longer running. I don't have any warning lights on the dash.

To answer my own question....
Eventually the injection warning light came on, and diagnostics identified an error from the lambda sensor. Sensor has been replaced, so hopefully the grand tour can resume in Wales.
