Vsc off, traction symbol and engine light on?

[Boom boom]

As above the car is in limp mode so 30mph tops and only about 2500rpm. Never had this before I'm reluctant to hand over £50 to have it scanned at the dealers but from what I've read it may require a re-evaluation gen of the cat which I obviously can't do myself as the limp mode stops this. Any suggestions gratefully received.

Thanks

Took the car out and followed the advice given, over 2500rpm for about 30 mins on motorway but no improvement. I don't think I mentioned the car is a diesel so I guess it's the dpf not a cat . Anyway I'm ringing the dealership in the morning and hopefully they can force a regen.. ££££££££
