I have this Golf Bluemotion 1.6 TDi back in with DPF issue, it was in just 4 months ago in limp home, problem was due to blocked DPF cleaned it through in situ with tunap cleaner no problem, soot accusation dropped right down car has been fine until now. Currently this fault will not clear 7388-P2463 even with pressure lines disconnected, I am suspecting the sensor maybe faulty even though it was replaced only 18 months ago due to permanent codes:
7345 2455 DPF DIFF PRESS SE CIRC HIGH
7346 2453 DPF DIFF PRESS CIRC RANGE PERF
I have been waiting all day for VW dealer to call me back.
I don't think there is any problem again with DPF as:
calculated soot mass 13.2 g
actual soot mass -6.51g
differential pressure 1.5-2 hpa idle 16.5 hpa 2500rpm
I may try to force a regen but was hoping to delete the code first because it will not rev above 2500rpm.
With the DPF pressure sensor disconnected the live data reads pressure as zero, will a healthy sensor clear codes with only the electrical connector in place?
I was hoping someone may know some test values to bench test this DPF pressure sensor?
