DPF ERROR CODE P242F

[Maddog55]

Was changing the oil and filter on my 08 1.6 Tdci when I noticed some black soot around the air box. On further investigation I found that the upper pipe on the pressure sensor was broken. Don't know how long it was broken but no errors. After oil change and fixed pipe started Car and engine malfunction warning started. Rechecked all the pipes and wires all looks good. But still error. Don't understand if it was broken for  awhile why no errors but once reconnect pipe errors appear any thoughts

thanks

The PCM is looking for a high pressure difference between top and bottom pipes, with a broken top pipe the pressure difference at the sensor was probably still in tolerance so not showing a fault but also not causing regens when it should.  DPF may be partly blocked now, causing high pressure differential and the fault code.

I'd try forcing a regen to see if it clears.

Will try a regen and update thanks

My Delphi software does not cover my car for regen. Where is best place to get. For scan and lead to be able to do regen

Is this the software needed for the cable

yep

Got the DPF holed and mapped out. Was advised not to do a regen because of the high miles could do more damage with the high rpm. Great job though no Dpf and the torque in the car has improved. Wait to see if mpg goes up though. No more issues. Unit came today as well so will install software And keep for future use
