Hi

Got this mare in on a rope from the AA
dpf was blocked solid & wouldn't go, no dtcs' at that time. removed dpf, tried several methods of cleaning, all to no avail.

Fit new dpf, got it started, dtc p2279 appeared, remove egr, clean & free off that's cleared that code, after programming ecu for new dpf, roadtest & p242F 58 & P242F 75 appear

Carry out tests as per TIS diagnose faulty dpf sensor, replace sensor & program, just p242F 75 re-occurs, smoked all pipework all ok, after a better definition of the code as i'm hoping to keep the owner on side.

Any ideas/advice? please

regards Steve
