I'll stick to my original answer.......you are not doing enough miles for a diesel,you can spend as much as you want on jacks,manuals and parts........it will still go into limp mode regularly
It needs a good run most days ie 30/40 miles on dual carriageway or motorway,a once a week thrash wont do it much good

Sell it and buy a petrol car

I had a few modern diesel cars, I do around 10k a year, most of my journeys are between 12 and 25 miles each way depending on where I'm working and not all on dual carriageways or motorways, I can honestly say I've never had any issues with DPFs or EGRs, the biggest killer is short urban stop/start journeys.

Bet you didn't get anywhere near the mpg stated.......and yes some diesel DPF's are robust but short mileage doesn't do it any good

I have a diesel with a DPF and the stupid thing does lots of regens, but the soot loading is low so thats a bonus i guess.

Lots of short journeys for me also.

Current car, an Astra K Sport Tourer 1,6 CDTi (136) averages 58 mpg on commuting, previous car a MK3 Megane Sports Tourer around the 60 mpg mark, car previous to that a Qashqai around the 50 mpg mark, no point in playing the stated mpg card because they are theoretical, based on a specific set of controlled conditions and do not relate to normal everyday driving in the real world.

Nasqueron

Mazda 3 2.2 (150) 64 plate - average around 50mpg, 8000 or so miles a year, when I do drive it's normally for sport with 30-120 min drives each way on motorways and a-roads mixed in with runs to the shop once a week. I do not commute in it, never had any issues with that mileage.



Will probably get a petrol or whatever is available in 6 or so years to when I think about scrapping it.

Thankyou tarambor and Adrianc. Sorry havnt worked out how to cut a quote yet.
What you both have said makes sense to me. I will start looking into the sensors.
Unfortunately the ex, who used to be a good reliable trustworthy mechanic , (not so much now)likes to play games, he frequently doesn’t finish fixing my car even though he knows our daughter travels in it.
I’ve bought a cheap plug in reader (with good reviews for fords) and a Haynes manual, trolley jack and axel stands so I can have a go at doing it myself. Would the MAF sensor be one to look at aswell?
Thankyou for all your help

The plug in reader you want needs to be one that does two speeds so it needs to come with a switch on it. This is the one I got

Also get Forscan from https://forscan.org/ or from Google Play/ Apple App Store. It will give you far more in depth information than a generic OBDII fault code reader will and it'll allow you to access individual computer modules too as well as do things like set some options or disable stuff that annoys you. There is a healthy forum on Forscan's website.
