Got a warning light and Reduced Performance Mode turned on just after setting off home from the Moot today. Made it the 70 miles or so home, but gonna have to take it in to the doctor next week I think.
My guess is either fuel filter needing replacing, or the infamous intercooler hose. Will have a poke around tomorrow to see if I can spot the latter for an easy-ish fix.
Don't panic with the odd light coming on occasionally. I presume you know the engine off & back on three times to clear a spurious warning regime? There are a load of sensors that can give an intermittent warning occasionally. Any garage with a diagnostic set will be able to tell you what it is.
