Hi All, I've just taken delivery of a 16 plate 939SP with 4,500 miles on it. It has the engine management light permanently on but no errors in the Service menu and runs rough, it coughs and splutters and pops back through the exhaust. I'm waiting for the dealer to take it back but in the meantime thought I'd run it past you guys first, might be something daft or simple (he hopes). Cheers.
