I had a blip on the power some time ago but it was after I'd let the tank get down to 15 miles or so from empty so I thought a bit of muck may have been sucked through from the tank. (The fuel filter was changed at the next service, 3k ago, for info)

This cleared on it's own though and was forgotten but I noticed an occasional relapse with power fluctuating, often when just cruising so it felt like a bit of a judder.

Today I hadn't got far and saw my first alarm of "Engine Fault, Workshop!" and the flashing heater coil symbol.

I do a lot of short trips which I'm aware is not great for the DPF so I've just taken it down the motorway for a couple of junctions and back. The warning / flashing coil was on within half a mile even though all felt well.

In case it's related to engine temperature I pulled over on the way back, turned off and back on again and the warning was back on again within a half mile. This time though I've acquired an engine symbol that's constantly on now.

Any thoughts?
