Mk7 Dpf Problem

[mich123400]

Hi!

After having the van into the garage with the EML on the problem was diagnosed as a blocked dpf. A forced regeneration was done but the light came back on further down the road. The van was then brought back, dpf was cleaned with dpf cleaning fluid and dpf cleaning spray and a wynn's additive was put in the fuel tank. The van was fine for about 100 miles of mixed driving. Upon starting a long motorway journey I stopped after about 20 miles to fill up and after leaving the petrol station the EML came on again. I continued my journey and after about 120 miles of motorway driving I stopped. When starting the van again the dpf light went off. It has been off since after around 1000 miles of motorway driving. Today after driving about 20 miles the dpf light came on again and then 30 miles down the motorway I stopped and started again and the light has gone off.

Anyone have any idea what the problem is? The dpf is regenerating but light keeps coming on. If the dpf was to be replaced is this just be a straight swap or will all the sensors and pipes have to be changed with it...? Also is this a very difficult job to do?

Thanks in advance... sorry for the long story

2012 Ford Transit 2.2 135ps
Around 44,000 miles

My money is on one of the following faults
Failed wiring loom to exhaust temp sensors
Failing vaporiser
Failing glow plug

All are very common dpf faults on Transits

DO NOT replace the dpf without having all these things checked first

Who has been working on it? Ford dealer? Or independent?

If it's independent it's worth putting it to a Ford dealer for a second opinion and probably repair

It has been with independent. They checked the vaporiser and said it was fine (it was replaced about 20,000 miles ago) and i told them about the wiring loom but apparently my van doesnt have it. Im not too sure about the glow plugs.

The van is usually used throughout the year for city driving of about 10-20 miles a go with the odd motorway run here and there. Could it be that the dpf is filled with ash due to many regenerations? If so would the dpf flushing fluid have removed the ash...?

Many thanks

sounds exactly the same as what happened to my 2012 tourneo I use independent mechanic replaced sensor £150 didn't change anything then replaced dpf £800 still didn't change anything last chance took to main dealer and it was the vapouriser and failing glow plug fixed in a day no problems since but another £800 moral of the story wish I had took it to main dealer first. hope this helps

Take it to a Ford dealer. Your independent doesn't sound as though he knows Transit DPFs because they all have a dodgy wiring loom

Just a follow up question Ake - Whilst waiting for my ford appointment, I was doing some digging and I found a fuse in the engine compartment (related to the vaporisor) not working. The fuse is number 29 in the book and it is labled Vaporisor glow plug monitoring. The fuse is not blow as I have checked with the original fuse and a new fuse. The fuse is not showing any current with the tester. Is this fuse supposed to be like this???

Also when you say failing glow plug do you mean failing engine glow plugs, failing vaporisor glow plug or either. Because glow plugs 3 and 4 on my van are not showing 12 volts, they are only showing 2 volts. Could this be related to the dpf fault?

Knobby I had a bmtroubleyou that kept blocking the dpf and the only fault code was the glow plugs .No problem starting cold so never changed them until the dpf blocked once again.Changed them and three years later and dpf is still ok. Does the dpf need them

The DPF vapouriser glow plug, I'd say yes....but I wouldn't have thought the DPF would need the engine glow plugs...they only on for a short time anyway, although, on second thought.... during a cold weather start without engine glow plugs there would be a lot of sooty unburnt crud going through the DPF until the engine warmed up a bit....Or...possibly (and most likely), I'm talking a load of bollocks as usual..

Maybe there's someone who knows a goodly amount aboot DPF's who can advise..??

That's my thinking too Knobby

Vaporiser fuse is only live when dpf is regenerating
