Unhappy P2002 Code and DPF won't Regen

I have a 55 plate Fiat Croma 1.9 150 Multijet with new DPF its done 120.000 miles and i keep getting Fault light on. I have a Snap on Various (Usless) and i get code P2002 and limp mode. tried regen holding 4th at 70 MPH 3000Rpm it won't regen for 1/2 hour. I'm seriously thinking on Taking it off and putting straight bit of pipe and finding an ECU place that maybe able to take out that function on the ECU? Car been seviced 4000 miles ago. I live in Brum. Any ideas?

Re: P2002 Code and DPF won't Regen

Could this be another Oil Degradation counter not reset?
When the oil is changed the service mileage should be reset, also the little known and more important oil degradation.
This will stop all regens after 24000 mles if not reset and many garages are not able to do this.

but not p2002

Thanks for reply

How can this be checked that the oil degradation has been done. We did do a service reset with my mates Launch. But we haven't got it at moment. I did get Fiat scan 16 free off GravilleB but cannot get it to work with an old ELM 327 that is working on a Windows 7 Laptop.

Thanks for reply dave. I've got car sorted. I registered multiecuscan 26 and reset service/oil and then did a forced regeneration. I took car out for an hour on motorway and A roads and no limp mode or management light so thanks again for all replies as in another thread a happy croma owner

Re: P2002 Code and DPF won't Regen

I know this is an old post but I've had a similar problem, my local garage has cleared the oil service indicator with a snap on obd reader but it keeps triggering the EMS light so I can't get anywhere near the motorway to regenerate... I'm in Nottingham...

Re: P2002 Code and DPF won't Regen

What is the code that it is coming up with?
The car won't often be able to regen when there the a fault code active
You'd likely need to fix the fault first before the regent can take place

Re: P2002 Code and DPF won't Regen

The service indicator is different from the oil change reset, are you sure which one they cleared?

Re: P2002 Code and DPF won't Regen

Almost certainly they have not reset the oil degredation counter in the engine ECU. This is different to the service indicator which is in the body computer. It needs Fiat specific software such as Multiecuscan www.multiecuscan.net. But it is reported that there is a "pedal pushing" reset method, see

https://www.fiatforum.com/500/306394...ml#post4339231

Which may be worth a try.
Really the garage should have done it properly though.

I thought I managed to reset oil and service with my snap on but ended up using multiecuscan to do it. You can regen using this program.
