Hi

2014 2.3 x250
Ongoing saga of p0089. I had it into fiat dealership who stated Dpf pressure sensor needed replacing and pipes cleaning out. I have done all this and done a static regen to get the Dpf fart light off (it only came on after replacing the sensor).

Van ran fine for 197km until background regen kicked in again. Which in turn causes the white smoke of unburnt fuel and P0089.

Fiat also said 2 new injectors but van runs great and no starting issues. It’s only when regen starts problems begin.

After static regen block level was down to 76% after maybe another 80mile of driving with p0089 on and off intermittently, block level is now 90%.

Any ideas Nick@Euroserv have you come across this before?

Thanks all.
