Brilliant mate all it is is common sense if you don't understand how it works you can't fix it iv repaired loads of these things and you my friend are spot on its a pleasure to watch someone who knows what he's on about

Hi im an automotive tech, only really have experience in gas diag. I was thrown for a loop when my boss gave me a ford transit diesel. Code is p240a exaust gas temperature sensor bank 1 sensor 2 below desired value. Tomorrow i will check the function of the vaporizer and possibly swap the temp sensor 2 with 3. HUGE learning curve going from a gas to diesel

Wow really helpful to the customer

I love these video's. I'm having problems with smoke coming from a Lexus IS 220d I just bought. Subsequently I've had to learn about the DPF system to try and work out the problem. Every time I watch one of these video's I learn enough to be able to isolate problems and have some idea of what is going on. I hope you might see this and be able to answer this question. My suspicion is it's a bad DPF pressure sensor. I think it is telling the ecu to set off the vaporiser at the wrong time causing a lot of smoke. Every time I disconnect the battery the smoke stops for a day or two. Would disconcerting the battery reset the soot level to zero?

I wonder if customer has tried to bang a few holes into it himself

I had the same issue and it was the fuse for the vape valve in the engine bay

Hi Jimmy. Is the egr maybe not fully closing causing dpfvto not reach 600 with vaporiser on?

The 2.2 transits when the vaporiser is on in regen EGT11 (pre cat) should be 440-450C. EGT12 (preDPF) should be around 580-600C, and EGT13 (post DPF) should be 630-645C. Poor temp rise on EGT12 would indicate poor quality/quantity of metals or damaged cat/dpf, assuming all else is good like vap working, throttle body and egr closing properly during regen etc. The cat is close coupled to the DPF so aftermarket DPF means aftermarket cat.. Been there before with aftermarket on transit, no good. Go to ford they do a ford reman unit for 800 and will give you 300quid off that for your old core even if its an aftermarket one. Reman one is perfect, no white smoke at all. hope this also helps someone like Jimmy it stops them going aftermarket route as its bad news.

I've got a bad case of ash blocking my dpf,do you recommend buying a new dpf or let the garage try and clean it I'm leaning towards buying the dpf I have heard horror storys in regards to baked in ash

If it’s aftermarket you know it’s only got half the material in it it should have.
