Faulty MAF maybe leading to DPF problems!
My 59 plate 2.0 jtdm came up with the engine management light a couple of weeks ago and car went into limp mode. Managed to nurse it to garage who diagnosed faulty MAF sensor and oil pressure switch, both of which were changed.
Car has driven fine since and Thursday of last week carried out a DPF regen on my journey into work (MPG and turbo boost both dropped off, exhaust note changed). The following Saturday I drove 180 miles down from Derby to Cambridgeshire and back so engine got nice and hot, no problems.
First thing Sunday morning started car and was greeted by engine management light and limp mode again. Another trip to the garage on Monday who diagnosed a blocked DPF, carried out a forced regen and everything is all good!
My journey to work is 25miles on dual carriageway each way and also a trip down to Cambridge and Weymouth to see family very regularly and this is the first time in 2 years of owning the car I have had any DPF problems.
Could driving around with a faulty old MAF sensor or the new MAF sensor be a likely culprit as to why I've had problems with the DPF?
Mnay thanks in advance
