Mondeo DPF Hell

Mick Shipman

I have 2012 Ford Mondeo 2.0 TDCI Zetec 140PS, got engine management light and malfunction warning about 3 weeks ago, brought it to a garage and they cleaned the DPF. Made zero difference to the car so I brought it back and was then told it needed a new vapourizer. Again it made zero difference, got 3 miles down the road with a lot of juddering and jerking before both lights came on again and back into reduced power mode.

So I rang them and I was told to bring it in for a forced regeneration which I did yesterday. I've drove about 80 miles on the motorway since this was done and the car is driving worse than ever. A lot of juddering and jerking to the point where it's painful to drive, particularly at low speeds. The car is also eating diesel, gone from 57mpg to 39mpg.

I rang them about this yesterday and was told it'll fix itself once it regenerates itself.

I'm fuming at this point, I'm down €600 and the car is driving worse than ever. Surely this can't be right? Have they missed something?

Seriously considering a DPF delete. Nightmare.

I can't help but don't go back to that garage. It might need live data reading.

Somebody will be along more knowledgeable to help, its quiet because of the rugby!!

Assuming the issue is restricted exhaust (sounds like it) confirming the back pressure is too high and where is is happening is what they should have started with. Once you have confirmed its too high (few ways that can be done) then a cheap way but effective to check this to drill small holes in the exhaust post cat and then post DPF, then you can check pressure at those points. the holes can be spot welded up after.

I hate to say but if they did properly remove and clean the DFP, it should not need any regen to work, and if your back pressure is still too high, then you have blockage elsewhere-

I will be going back to that garage. If I go somewhere else, they'll want another bag full of money that I don't have.

To be fair, I've been using them for a while now and they've been great but they seem clueless with this problem. I don't think they test drove the car once in the three times they've had it or else they wouldn't have gave it back to me.

They've done 2 forced regens which surely can't be good for the car? Not to mention the amount of bloody diesel it wastes.

Very frustrating.

They may have forgotten to reset the dpf adaptions/tell its had a new dpf or if they did then you may have a intake intercooler bypass butterfly problem..have seen this before on peugeot 2.0hdis which have the same engine.
