Had the same thing pop up on my MA just this week @ 189,000 km.

It was also running fine so gave it a good 45 min run on the highway as it also had a lot of short trips leading up to this. Also took it up to 4K RPM from standstill a couple of times and fair to say the exhaust cloud was significant.

Long story short got home, turned the car off, waited a couple of mins and started it again - engine light still there. Planned to have it scanned the next day. Jumped in the car in the morning and engine light is off and has been fine since then.

I'd be scanning it asap as suggested if you've tried the above, waited and the engine light is still on. I should add I've had this happen once before and took it straight in to be scanned and the DPF was what came up so had a feeling it could be the same thing.
