Afternoon all, Having recently had a split DPF pressure sensor hose and broken clamp on the DPF fixed it now seems blocked. I have tried to force a regen through Forscan however it gets to 11% fails and no engine revs. (I've been told I could sit there with my foot on the throttle for 5 - 10 mins but surely this isn't safe) Either way I was just wondering if anyone had any suggestions as I have added http://www.eurocarparts.com/diesel-system-additives/searchkeyword/dpf but still no luck and considering using http://www.eurocarparts.com/ecp/c/Ford_Focus_1.6_2008/p/car-accessories/car-maintenance-accessories/maintenance-fluids-and-greases/cleaner-and-degreaser/?NOR2897380&0&cc5_104 I was just wondering if anyone had any experience on using them or any other suggestions? Any help would be much appreciated. Thanks
Please bear with me on this one. Until this week I haven't heard of a DPF. My last car was a 2010 1.4tdci Fiesta Edge, fitted with a DPF. My journeys mainly consist of trundling around town with the odd motorway run. And I had the Fiesta for 2 years and 8 months, and the only problem I ever had with that car was the rubber seals around the fuel injectors. There was not any other single fault. 2 months ago, I bought a 2009 1.6tdci Focus econetic. Reasons being i can't afford to run a petrol car with the cost of fuel and tax. And early this week, whilst doing around 60mph the engine lost a lot of power, and on the dash all that was displayed was "Engine Malfunction". I had no prior warning about this. So took it to my local mechanic, and he explained the issue, and cleaned it and now all is well. So I've done some reading about DPF's, and 9/10 people are saying to stay away unless you're on the motorway often, which makes sense considering how a DPF burns off the soot. But I'm a little confused/worried. My previous fiesta had 50,000 on the clock when I bought it, and I changed it at 60,000, and I never had a problem with the DPF. And this focus has 86,000 on the clock. So, what I would like to know, is, 1) Did I get lucky with the fiesta? 2) How long can a DPF go without cleaning just driving around town? 3) Will me taking it onto the motorway for 20 mins clear the filter? 4) If so, how often would I need to do a motorway run? Also, I have read that to begin burning off the soot in the DPF, the engine revs need to be around 2,500rpm. Which is a slight issue, as the other night on the motorway for about 3 miles, at 70mph in 5th, the engine revs only hit 2,000rpm. So, only hitting 2,000rpm even on a motorway, does that indicate that I have an "active regeneration", as opposed to a "passive regeneration'? I'm aware fundamentally, I've made an error in buying this car, I only buy diesel to keep the cost down, with tax and fuel. I'm just wondering, will everything be ok, if I take it for a high speed run say every 2 weeks? After discussing this with my father, he is under the impression that, I didn't have a problem with the fiesta, so it's likely that you will generally be problem free with the focus. After paying £200 for the DPF clean, I'd like to help the engine/filter as much as I can, I also have to consider, that I have no idea how the car was treated by the previous owner. Any help/advice is appreciated.
I have a 09 focus econetic 1.6. i have a problematic DPF. i haven't had the car from new, it has 88K on the clock, so the DPF is passed its lifespan. i am unsure whether to get it repaired though as I've been told its £1,000 +. i knew nothing of DPF's before i bought it, i just wanted a car that ran cheaply. and I'm now aware that these cars with DPF's aren't any god for town driving, i usually only drive roughly 4 miles a time, day to day. so i can understand then why it wouldn't be regenerating. but what I'm confused about, is i previously had a 2010 fiesta diesel and that also had a DPF as they have been required since i believe 2008/9. I've just taken the car on a 40 miles stint on the motorway, but the engine malfunction light is still on, and i still hear it as i turn the engine off. my concern is, i don't mind paying for it to be repaired/replaced, as long as it runs ok in the future, I'm so confused, cos i had the fiesta for 3 years, and never had a problem, but it had only done 55K, and not one single dpf problem, even though my driving is exactly the same. I've paid a mechanic to clean the dpf when yellow warning light came on. tried adding additive to fuel to help clear the dpf. yellow warning light is not currently on, i just have a engine malfunction sign displayed only when i turn the engine ON, not when the ignition is on. (I'm assuming its the DPF) no other noticeable problems. and i can't really afford to keep taking it to be diagnosed. £25 a time i also have a maxiscan ms309 code reader, but its not picking up the engine malfunction display, will they only pick a code up if a yellow warning light comes on? I'm not sure if its working properly though, as i unplugged it with the ignition on, and its a little slow turning on.
I'm hoping someone can help me or at least tell me I'm not the only one with this problem. I bought my Focus 57 plate 1.6 TDCi 18 months ago & the dealer fitted a new DPF just after I bought it due to a DPF error on the display. Since then I've never had any DPF error messages. Over the last 18 months (& 48,000 miles!) forced regenerations have become more & more frequent. When I bought the car I didn't notice any, then I started to notice it was doing one every day (my 90 mile round-trip to work), then every journey, and now they're continuous i.e. 5 mins after I leave home the first cycle starts & lasts about 7 mins, then I get 2 minutes of normal driving before the next regeneration cycle starts. You can imagine what this is doing to my MPG! My commute consists of 30 mins of motorway cruising followed by some clear A-roads & finally 5-10 mins of slow traffic. I cruise at 55-60 on the motorway for economy and, according to what I've read, it should need to do any forced regenerations under those circumstances. I know it's doing the regen by watching the average MPG. I reset it when I leave home & it builds nicely for the first five mins, then starts to drop again while the regen takes place, before recovering a bit in between cycles. When I get out of the car at the end of the journey the cooling fan is always running & I think this usually happens during regen. Neither my local garage or the Ford main dealer has got a clue. The only diagnostic fault they've seen is a regeneration failure which may have been logged after the EGR fell to bits a few months back & had to be replaced. I can't afford to replace the DPF on the off-chance that it will cure the problem & in any case I don't think it should be blocked. Could it be a sensor fault? Can the entry/exit pressure sensors be replaced individually at a reasonable cost?
