Decarbonisation?
1 - 6 of 6 Posts
If the car thinks it needs a DPF regeneration it does one.
But 43mpg is low for your car. When did you last get it serviced by Volvo? Did you bring the low MPG to their attention?
I would think a 20mpg ish drop in economy points to something more serious than just carbon deposits

i'm assuming you spotted the adverts for carbon cleaning and a promise to restore performance? very dodgy ground if you ask me, basically the system has been high pressure sold to garages to earn more bucket fulls of cash from motorists. I'd invest in a fuel filter and air filter and bring the next service forward. Choose the garage wisely, as an example, my old C30 went to a specialist independent and they noticed a vac pipe hanging off which changed the car completely. hoping this helps

Thanks for the input guys. I’ve only had it 19 months and had it serviced twice by a local independent. Might try a specialist independent next time but it’s not due a service till September.
I’m retired now so not much mileage accrued by myself. In fact mostly short journeys bar a run along the motorway behind where I live for about 6 miles or so to ‘ warm the engine up’ each week. I did a run down to Southampton from Liverpool last year. I think I averaged about 80ish mpg on that run, at 60 ish mph all the way. So not so bad. I’m running on Prem diesel from Costco since I bought it, thinking cleaner engine, better mileage. Is a specialist service the way to go do you think? Look forward to your input folks. TIA

Once your sure all is ok, theres nothing wrong with having the service done anywhere, but a Volvo dealer or specialist will know these cars weakness's and sort little issues along the way. If shes doing 80 on a run, id say theres not much if anything wrong 
(best engine option btw)
(best engine option btw)You say mostly short journeys bar a run for about 6 miles or so each week. I suspect your main issue is the length of your journeys. If they are all 6 miles or under, you can expect your fuel consumption to be on the high side, as a) you are predominantly driving the car with a cold engine which will use more fuel, and b) driving around town, albeit "pretty conservatively" with stops, starts and gear changes, is also going to use more fuel than a sustained run at a constant but moderate speed compatible with a gear using low rpm from the engine.
A relatively modern diesel car with emissions control technology is I'm afraid also totally unsuited to your usage pattern. They are only really suited to journeys with plenty of driving at a moderate to high rpm over uninterrupted journeys of 20 minutes or more with little slowing or stopping. More info in the post below, but a petrol engine (or electric/petrol hybrid) would be much better suited to your usage.
Taking the car for a 6 mile journey is achieving nothing. It really needs a regular trip of preferably around 50 miles or so, but at a minimum about half that, to fully warm up and spend some time operating at optimum efficiency. The journey should include at least 20 minutes or so of uninterrupted driving at moderate to high rpm to provide the optimum opportunity for activation and completion of the DPF cleaning process, which is automatically activated by the car as required, but only if the conditions for its initiation and completion are met by suitable driving conditions. I would do that at least once a month as a bare minimum,

DPF SHORTAGE V40 D2 ?2014YR.
Hi I was wondering if anyone has had the same problem as me. 2 Weeks ago my car went in for full MOT/Service. My car failed the MOT on emissions and im told it needs a new DPF. The problem is. The dealer cant get one because Volvo GB havent any, I have contacted Volvo Uk and they say the same...
