Hi all,

Just bought a 2021 focus 1.5 diesel, has about 1 month warranty left.

I'm looking to get the dpf and adblue removed, it's guzzling the adblue.

I've looked into having this done but apparently since around 2020/21 the ecu is locked and unable to be remapped.

The car is currently on around 57k, I've only used it for 1 month and have had the dpf full warning on already.

Any suggestions as to what can be done alternatively ?

 

Thanks in advance ☺️

Isn’t it better to investigate the excessive adblue consumption? It could be a sign of other issues. 
 

I’d have also thought you’d need the emissions system to pass a mot. 

sort the dpf and the AdBlue consumption should come down.

If you have only run the car for a month, what sort of use is the car getting?

All short runs where it doesn't get fully up to temperature?

Many people have bought diesels because of the fuel economy, only to find that the way they use the car causes blocked DPF's. Modern diesels need to be given a good long run on a regular basis, they are not suitable for continuous city use.

Also, it is illegal to remove DPF's or ad-blue systems, and can be an MOT test fail.

Absolutely as Alan has stated.

Diesel cars are great but not for short trips constantly. They need a good run at least once a week of at least 50 miles and at motorway speeds. 

'Modern' diesels regen at town speeds...even my 2012 Golf does.  They don't need motorway use at all.  The engine does need to be kept running though, and ideally in flowing traffic rather than inching forward bumper to bumper.  Switching off mid-regen is what causes them to fail.

I agree, modern diesels will regen at town speeds, BUT they have to be fully up to working temperature to start the process. On regular short runs, this doesn't happen.

Both my Mk3 Focus & Mk6 Golf would often start regens on the 1 mile trip to the supermarket in light traffic.  Obviously they failed as I cut them off, then they'd start again on the 1 mile trip home, which I'd cut off again.  Think my maximum failure string was about 6 in a row on the Golf.  Still never saw a DPF light.  The regen would complete in about 3-5 miles on the next run.

Back in the day I did have frequent regen issues with the Eolys DPF on the Mk2.5 Focus, despite a regular 90mph blast to the seaside each week.  But since moving to coated DPF's I never had another problem.  The Golf didn't even pass 40mph in the last 1.5 years I drove it.

I remember getting my 1st Ford diesel and joing Talkford as it was Mondeo based. I soon learnt of DPF issues and Forscan. 

I soon started to do forced regeneration once a fortnight. 

Within months I got it remapped and DPF delete. OMG what a transformation and it never failed a MOT after either. 

MOT regs changed in 2018.  That's when DPF deletes, any emissions device tampering and any visible smoke from a DPF equipped car became a fail.  Obviously some testers are more observant than others.

My old Mk2.5 did eventually fail for the DPF delete.  Although I'd sold it and bought the Mk3 by then.

That's correct Tom but from my understanding the MOT tester couldn't tell on most DPF deletes because they were obscured by under body panels and they weren't allowed to remove them.

How it is now however I've no idea as I wouldn't touch a diesel with a long pole.

Doing short journeys even if it's not causing the DPF been blocked your fuel economy can't be that great??  Would you not be better off with a petrol car?

The car has an issue.

Take it back and get it rectified or rejected

Not at all.  Fuel economy was always over 50mpg per tankful.  Far better than any petrol of that age with 140bhp and over 300Nm of torque.  Plus the road tax was only £30 a year.  I genuinely don't know how anyone can afford to run old petrols!

Of course, technology has moved on since 2012.  I briefly had a 2021 1.0 EcoBoost MHEV which had 155bhp, enough torque to rival the diesel, and averaged around 45mpg on the same journeys.

I had to stop driving altogether around 2.5 years ago.  I would now be much better off with a fully electric vehicle.  But I would need to move to a ground floor property and have access to home charging before that's a possibility.  (Definitely not starting an EV debate in this thread lol!)
