Loadmaster 402 Report post Posted January 5 I'm referring to modern diesel engines here, the sort you'd find in a two year old 3 or 5 Series for example. I've never owned a diesel car, but in the 'old days' persistent short journeys in one could/would cause a problem for the DPF, with management lights coming on and meaning a trip to the garage. That would be unless you went for a blast every so often to clear all the crap out! Posing this question due to the lack of petrol engines in modern 3ers and 5ers... So, best to avoid the DERV?

sshooie 620 Report post Posted January 5 imo, yes I would avoid derv for short journeys. 1 Loadmaster reacted to this Share this post Link to post Share on other sites
cableguy 1,151 Report post Posted January 5 I'd avoid if it's only an occasional or short journey car. Speak with a few local garages/independents and they will tell you that a good proportion of their business is DPF and re-gen related on diesels. As an example, Diesel sales fell by over 20% in the last quarter of 2017. A sign of the times that things are changing...

A sign of the times that things are changing... and yet other emissions are up from petrol i heard on the today programme so its swings and roundabouts. I don;t think any ICE owner can be smug But i would avoid short journeys too - i try and walk when i can, across my town its often quicker to walk anyway! 1 Loadmaster reacted to this Share this post Link to post Share on other sites

Lack of petrol 6 pots in current BMW line up prompts my post. Also, the future of the diesel car is a concern. Share this post Link to post Share on other sites
F10 530d 77 Report post Posted January 5 My journeys are often no longer than 20-25 mins and I haven't experienced any DPF issues from this. However I do tend to give it a good motorway blast every few hundred miles or so to try and encourage a DPF regen. 1 Loadmaster reacted to this Share this post Link to post Share on other sites

A sign of the times that things are changing... C. Actually sales of all cars fell by 5% last quarter. The drop in diesel car sales can be attributed in part to comments made by a number of ill-informed (or well informed but with their own agenda) politicians 'demonising' and vilifying diesel cars by claiming particulate pollution was more serious than greenhouse gas emissions. Recent tests have shown that the new generation diesels are actually cleaner than the equivalent output petrol cars and the old issues of DPF 'clogging' is not the issue it once was.

535i Andrew 1,474 Report post Posted January 8 Today, If you buy a 2 year old Diesel and do short trips in it, it probably won't give you any grief (other than the usual BMW issues) until it's 5 or 6 years old. Then Punt it and buy another one so it's someone else's problem. The 6 pot Diesels are nice enough engines and in twin turbo from, spectacular. 1 Loadmaster reacted to this Share this post Link to post Share on other sites
cableguy 1,151 Report post Posted January 8 Some good counter arguments listed above and I have personally just sold a Turbo Diesel after four and a half years ownership, however there is no substitute for the refinement of a petrol in comparison. I think any motoring expert or motoring journalist would recommend petrol over diesel for short journeys. C. Share this post Link to post Share on other sites
McFar67 65 Report post Posted January 9 Had to buy diesel when I received car allowance, the majority of journeys during the week, no more than 5 miles each, except for business trips. Tried to circumvent any potential issues by sticking to shell v power fuel 1 Loadmaster reacted to this Share this post Link to post Share on other sites
Retset 94 Report post Posted January 9 I do 95% long trips so don't mind the devil's juice but wouldn't consider one if I did many short journeys. My Dad has an XF Sportbrake 3.0D and doesn't do many long trips. Recently it threw up the red DPF warning which means game over, go to stealer and spend £1800. WTF? Anyway, his trusted local garage was able to clean the DPF for under a tenth of that.... He'll get petrol for his next car! Share this post Link to post Share on other sites
535i Andrew 1,474 Report post Posted January 9 Bloke at work paid £2300 for a new DPF in his XJ Jag. He did short trips in it. He then sold it and bought another Jag, but this time he listened and bought a 5.0V8 XK! Share this post Link to post Share on other sites

pauliexjr 744 Report post Posted January 10 £2300 for a new DPF? FFS! My wife drives like Miss Daisy and has had the EML come up on a couple of occasions, I simply take her Nissan Juke for a quick, high-rev burn and the light goes out and stays out for another 6 months. I do the same thing with my diesels before an MOT and have never had a failure or even advisory on particulate emissions, but I suppose it's horses for courses..

My wife drives like Miss Daisy and has had the EML come up on a couple of occasions, I simply take her Nissan Juke for a quick, high-rev burn and the light goes out and stays out for another 6 months. On the Jag, you get an orange warning first which means go and drive for a bit to regen the DPF. If you didn't see it, ignore it or whatever, it goes red. This is supposedly only sortable for about £2K at a dealer who replaces the DPF. Absolutely criminal! I think it cost about £150 at a reputable local garage to pop it out and clean it.
