Indie garage nr Bishops Stortford to do Ford regen?

[Craigie]

Brother lives in BS and his C Max has went into limp home mode. When AA arrived faults had cleared but he said it smelt like the DPF was needing attention.

However he has phoned round and no Ford garages can take him to week after next.
Anyone know of any indies in BS that have diagnostics for this and could force the regen if necessary?
