Got the following error code on my 2010 W204 Cdi 2.12454, DPF Differential Pressure Sensor Circuit Low
Cleared the fault and went for an Italian tune up, about ten miles at 3000rpm.
All good, for about fifty miles but it's come back again.
I guess I was hoping it was a DPF that needed regenerating.
Beginning to think that it may be a faulty DPF pressure sensor or tubing blocked.
Anyone any experience of this and could point me in the right direction on how to fix this.
I'm used to keeping a range rover p38 on the road, so not frightened by spanner work. But totally not used to these engines so don't know where to start looking.
Thanks in advance
