so what is this dpf regen process... is it just a posh !Removed!, with all the cack blowing out?

how does it work, and if it does 'go off' will it be like the sonic boom from concorde [rip] flying past  :wacko:

The regen process for the dpf happens when the filter gets really hot (motorway driving 20-30 mins) and in doing so it burns off all the bad bits it as collected thus cleaning itself . If it never gets hot enough then you run the risk of all the bad bits blocking the filter and causing power loss due to the fact exhaust gases can't get through filter so choking the engine . This is what I'm told could happen and like I said I'm just passing on info hopefully correctly if not then I hope someone corrects me.

as posted in another thread by myself

 

as the pressure in the DPF rises the car decides to do a regen. in order to get the DPF to burn the soot its collected it has to get to about 600 degrees celsius. the engine management will then start to over fuel (it will spray some fuel in on the exhaust stroke) which will then be ignited in the filter to burn the soot. most of the fuel is sent into the DPF but some will get past the piston rings and will collect in the sump.

the reason for not topping up the engine oil on a diesel is because as its carrying out a regen cycle the oil level will rise and will get diluted with diesel. once its above max there is a possibility that the engine could run on the oil untill it goes bang.

if the oil level is on the dip stick but its low, leave it for about 1500 miles and then recheck the level you could find its gone up'

Finally got the car back this weekend. Seems no different to drive than before, but MPG is now a lot better. I used to get about 50mpg when careful, now i'm getting about 55-57mpg. Admittedly part of this is down to the better weather, but it wasn't ever that high before the winter.

 

I was worried about the cost when the mechanic said it was the DPF, fearing that it'd be £1000+. But the DPF (and the glow plugs, which were dead) were changed for... £550!! My family have always used this garage and are always impressed by their cheap prices, but this was still amazing!

that is an excellent price by anyones standards, let alone given your location!

 

I have to say, given how things have changed and the VOSA rules are passed, I would be more likely to remove my DPF and remap the engine for under £300...

This is good to know. I'll be needing this in 3 years or so. I know these things get a bad rep but if they're driven properly you probably break even with a non-DPF car, and stay on the right side of the emissions rules!

Well, using Honest John's real MPG for a 1.6 focus and the price of fuel round my area, i'll save about £580 on fuel and nearly £100 on tax this year, so i'm still up. I've also had one other repair which was the alternater, which is not specific to the diesel anyway. Given that a similar specced focus but in a petrol would only be about £700 cheaper to buy according to Parkers guide price, it'll take quite some repair bill to make a petrol cheaper.

Over three years, (not including repairs, or insurance which varies each year, but including the purchase price) I will have saved £1400. Thats still £850 after the repair, and thats even assuming the petrol never needs any work done.

 

The only other non-dpf option would be the 1.8 tdci, which I admit would probably be cheaper, however that wont be an option in the future when all diesels have DPFs.

 

All in all, I'm pretty happy with my choice of engine :).

Mine, which is a 2008 (58) 1.6 TDCi, does of course have a DPF, and is £30/year tax. The Ford Etis website classifies mine as "Stage IV + DPF Emissions". Can't check his as it doesn't appear on Etis unless you use the VIN.

 

Edit: Just found out (*): "Also, cars produced on or after 1st January 2007 must be Euro IV compliant[...]", so that explains it. I guess any 1.6 TDCi Focus after 01/01/07 will definitely have a DPF, before then, only the "Euro 4" ones will.

 

I've got a 90bhp 2008 and it has no DPF. Only way to be sure is check the VIN plate on the driver's side.

Always forget about the 90 bhp models! Pretty sure all the 110s do, unless someone knows better?

I think the 110s all do, but don't quote me on that. And I also think some 90s might and some might not..

it is recommended to clean your DPF with a good run down the motorway keeping the car at 3k revs for 20-30mins as said previously.

If your in the tyne and wear area, i can probably set your car away to carry out a forced regen (the car wont move)

 

Dealers have kinda locked this down in terms of fixing...you can either:

 

- remove filter and get a good remap of car to take it out

- replace fluid yourself, take filter off and power wash it and get dealer/indy or IDS holder to reset counters

 

- go to dealers and spend ££££

 

but in terms of which engines i know PSA do not fit DPF's to the 90bhp engine but 110 and above does...being that ford use some PSA engines this may be true.
