Welcome to Just answer, there are a couple of things that could of caused this, the first is a faulty temperature sensor that then wont allow the DPF to regenerate causing the rough running.

The second is that the DPF has got too hot due to incomplete regeneration cycles and the exhaust is blocked.

I would start by replacing the temperature sensor then give the car a good run.

I hope this helps, best regards, Vauxdoc.
