dpf will not reset

[driver61]

hi lads my x5 e70 2008 30 sd as dpf service come up on my idrive .I had it checked out by bmw and they found no faults and said that the dpf was working fine . I also took it to a indy who took it on the motorway to do a regen which my car did ok they also did check for faults and found no error codes both bmw & the indy tried to reset this dpf service light and failed to do it. The car it self drives great .Is there any one out there with this fault any ideas to solve this

Sounds like the DPD differential pressure sensor Is duff,

thanks horizon where is the  DPD differential pressure sensor is this a easy fit

There is a pressure sensor fitted into the DPF, it reads the upstream pressure before the DPF, if the pressure increases due to a restriction in the filter, as it can't pass enough exhaust gas quick enough it triggers the warning light. If the adapaf has regenerated properly and you still are getting the light on, maybe it's reading Incorrectly.
INPA should show the readings obtained. Common problem on Some VAG cars so it's possible on Beemers.
If it drives ok and they say its regens get, and the light is still on, maybe worth trying .

Thanks  horizon to fit the pressure sensor can it be done with out taking it to a garage or is this a simple plug and go job
