I'm after a second opinion really ref my mk4 mondeo 2.2tdci dpf.
When I first bought the car the garage I bought the car off fitted a new vaporiser valve and a aftermarket(euro car parts) dpf. The car seems to of been fine up until the last few months.
A few weeks back I got the P2463 fault code. I removed the dpf and and look to see if it was blocked. It looked ok. I made sure the vaporiser valve wasnt blocked. It was clear. I did a regen then I thought the car was ok. I wired a led up so I know when the car is doing a regen. For the last few weeks the car is doing regens nearly everyday. I noticed last week and today that the tail pipes are covered in soot and the fumes stink. The car has never been like this.
I'm thinking is the dpf knackered again cause it's not regainiregening properly and that's why the exhaust is sooty..
What do you guys think. Has anyone had much to do with dpfs. I've done plenty of regens on Van's but never known them to be sooty.
I squirted brake cleaner into the fuel feed pipe on the vaporiser. I also used a air line too. Considering that the fuel vaporiser has only been on the car for other a year the nut was tight as fook and wouldn't come out. So when I did my tests I just felt for the air blowing through the exhaust pipe. I will try another static regen using my tester and see if it will get rid of the soot.
Try some dpf foam cleaner that goes into the sensor for a cheap option, i done my dpf , cleaned egr with it in my kitchen sink then done dpf again to be double sure , not had that code up since but i was thinking is there a chance that it could build up in the back box as well? Dpf`s are a pain mate lol
I love the car but this is starting to piss me off. I will try and get some cleaner from work and try that.
I've had a few vans at my work where the dpfs have been blocked
.I've removed lambda sensors squirted this cleaner in then regen them. They smoke look fook with the cleaner in.
Use a mitivac on the vaporiser fuel inlet glen. If the needle moves at all there is a blockage. Are you still only doing short journeys? If it doesn't complete the regen it will try again the next time conditions are right. Can you monitor the exhaust temps when its doing a regen? Rear one needs to go above 500°c.
Thanks for that info. I'm gonna let the mrs use it more cause she does more miles than me. I've got a ForScan diagnostic tester coming so I can do proper checks. The car has been for for ages it's just the other day I noticed the pipes were sooty and it stank.
The wife used it yesterday and said the car was doing a regen on her way to work but didn't regen on the way back.
It might just be me worrying about nowt,I just like my cars to be right.
I've fitted the sensor and now.i have a P2463 code which is saying the voltage is wrong. It's a permanent fault too so I think the new switch is faulty. I'm gonna have to check the voltage going to the sensor when I get chance.

Hi Glenn, I was talking to my Postman the other day and he told me they have a lot of problems with their vans not doing long enough journeys to get the DPF valves hot enough. He said they sometimes go in to limp mode.I think you are a mechanic for the Post Office and was wondering if you have come across this? I know the Post Office vans are not Ford Mondeo's but maybe related to your problem?
He will be on about the Fiat doblos there always doing this. We have to regen them all the time.
I only wanted to try one of these pressure sensors cause it was cheaper than paying for another dpf. But I think the eBay special sensor is faulty. I need to put my FORscan tester on the car and have a play about with it.

This is what makes me laugh about DPF’s and EGR’s.
People take them out and clean them! So we catch all the crap that would have fallen to the ground (admittedly bypassing our lungs) anyway then we clean them out (usually with chemicals) and the dust gets directly inhaled by the fitter/their colleagues/DIY cleaner and washed into the water system or onto the ground.
Its like when you see someone boot a car for the first time in a while and it just blows hundreds of miles of stored soot out in one go.
Bit like everyone going around wearing a filter mask then getting home, taking it off and patting it out on the sofa.
I refit the original pressure sensor. I removed the fuel vaporiser fuel pipe and used an air line to blow it out. I dropped downmiddle section of exhaust to make sure the vaporiser wasnt blocked.
I did a regen using my FORscan,loads of shit came out of the back. So far my car hasn't done a dpf regen since. I dont know if these cold days are effecting it though.
I bought a genuine second hand dpf for the car. I fitted it yesterday. Looking at the pics I think the aftermarket dpf is looking a bit blocked to me.
you can see the difference between the genuine one and the aftermarket dpf.
I've been out in the car today and the car did a regen. No smoke out the back of the exhaust like it was doing before. I've reset my trip computer and see how long it takes before the car does another regen.
Well car is back to normal. smoking like fook when doing a regen when I'm driving it. I was chuffed cause I thought I had fixed the fooker but obviously not.

I haven't got a clue now what to do.
I hate modern diesels they are a pain in the ass aren't they mate. Choked to death for emissions never going to work long term

Yeh it's getting on my tits now. I might have to go to a diesel specialist now cause I haven't got a clue what to do next. I've never owned a diesel and this car has put me off owning them again.
That's how my dozers work, I wondered if it's getting hot enough to burn it off ?
I haven't got a clue the vaporiser was new about 2 years ago. I also think the ecu injects fuel on the exhaust stroke too to help with the regen process.
Had an interesting one at work the other day on a euro 6 LF chucking on the eml light and going into limp mode. The new ones have egr and ad blue. Haven’t really had any really involved issues with one yet. Daf technical was pointing towards the cat or a nox sensor or ad blue quality. It had are trusted ad blue in it so that was ruled out. We can do a lot with the workshop diagnostics so we road tested it loaded. You can monitor exhaust temp before and after the cat. Nox level before and after the cat. Engine torque and fuel pressure as they only make high nox when working hard. The laptop also works out a nox conversion percentage which ends up being pretty much zero. That had a new cat in the end. I’d never buy a modern diesel there to complicated now and cost a fortune. Sell the thing and buy something else. Egr only works on the dafs to aid heating up the engine then the ad blue system takes over as the main emissions system. Still get blocked egr faults though. Always changing egr coolers and cleaning out the system. They monitor pressure in the inlet manifold and exhaust manifold also pressure difference before and after the dpf.
they can only breath on there only waste for so long before it causes a problem lol
My oil service light also comes on all the time. Easily twice a month.
Could my injectors be dribbling a bit?? I honestly dont know ha ha.
When I was looking for a new ( secondhand ) daily to replace my old Renault Laguna estate I was after a Mondeo estate but I could'nt find one that was with a petrol engine, they all were diesel's and most auto's which I did'nt want.I am very pleased with my Focus estate with the petrol ecoboost engine,manual 6 speed gearbox,good performance ,good mpg and no dpf valves or other diesel related problems. No wonder it is starting to piss you off Glenn. Trade her in for a petrol engined one and forget all the hassle!
I wanted mk4 titanium x sport but the only petrol version the did was the 2litre turbo ecoboost engine. They only came with an auto box. So I went for the 2.2 diesel.
I've had it nearly 2 years this year and I think about a year of it is with the problem I've got.
