Hi since my 2.2d went into a active regen it keeps throwing out this code I have poured a bottle of dpf cleaner into the tank but hasn't made an improvement. The performance is faultless she drives just as she should. The code is differential pressure too low bank 1 . Anybody got any ideas on a fix and should I be worried . Or do I just need to give it a good seeing to on the motorway

Several other posts on S type, xj, etc. Seems more often than not that the pipe had split, melted or disintegrated.
