Discussion
Morning lads and lasses.
Apologies if this is the wrong section to write in, but new to PH, so bare with me.
I've recently changed jobs and although I bought a new 1.0 petrol Ibiza last year for money saving reasons (cheap to but and run as my commute was 35 miles each way, every day, 5 days a week), I have been toying with the idea of changing cars to a fun used diesel (330d,335d) but worried the fun will subside when it comes to the DPF needing high temps. My new commute is only 8 miles, but 2 of which are on a dual carriage way so can give it beans to help heat the DPF. Will this still not be enough for the cars health? As in for fun should I look back to petrol? Ps once a month I do a 45 mile trip, 4 times, to see my daughter, which involves motorway driving for a good half hour. Any help is appreciated.

An 8 mile trip in that engine will likely just about get to temp by the time you get to a stop but its not going to do much to help the DPF, plus its going to give you 25-30mpg for that sort of short trip.
We have to do 8-10 miles in both of our N57 engined cars to get the temp up to the half way point on the display.
The problem you have is that you don't know the DPF condition of the car when you buy it. If its been used for long journeys and its fine, your few longer trips might be ok clearing it but if its been used for short ish journeys already, you might end up tipping it over the edge with the short journeys you do.
The problem when looking for a BMW in the 3.0T arena for under £20k is that the diesels outnumber the petrol's by about 50 to 1, its even worse if you are picky on spec or colour etc.
Personally I wouldn't take the risk in your position unless you go AUC where you get a warranty.

I spent a few years doing about a 20 minute commute with about 10 mins of dual carriageway in my diesel Octavia. Never had a problem with the DPF but the fuel economy was probably 20% or more down on what I get on longer journeys.
If you're not doing the mileage to benefit from better economy, you might well be better off looking at petrols.

I think petrol is the way forward here, doesn't look like your total annual mileage or daily use would be ideal for a diesel motor, having said that 30\35D engines are very good and quick on the real world.
I have no issues with my 335d for short journeys, with a weekly or monthly longer journey. In colder weather, the oil temperature will only just reach its stabilised point at 10 miles or so. I will probably resume a few more longer journeys again. In your case, I would stick to petrol (or EV). The Ibiza sounds ideal for that journey.
Had a 435d. 25 minute journey of 14 miles to the practice.
Up to temp by 10 mins when not too cold out.
15-20 mins when winter. So only 5 mins at full temp then.
Checked dpf counter using one of those phone apps at 43k miles and it read 187,000 miles of life. Calculated on soot/ash mass.
Just make sure you give it a good drive at least once in a while. Like an hour of motorway or so. Will slow down carbon build up (cbu).
Short journeys meant lost economy and it was often in the low 40’s mpg. That was without air con. I also lived on a nsl road in Devon at the time. As soon as I turned right I’d have to get up to speed to avoid upsetting traffic.
YOLO!

My last car had a DPF (without adblue) and I do a lot of short journeys. Expensive Archoil AR6400-D Max and BP Ultimate Diesel helped with Passive Regen but I still had to go out on a run every few weeks and do an Active Regen (I had a diagnostics tool which allowed me to monitor soot levels and manually initialise and Active Regen and be in control because there's no guarantee that the car will initiate one and then you can end up with a blocked DPF). Not only did this cost me a lot in fuel, but also in more frequent oil changes to combat oil dilution and more importantly it took up a lot of my time going out for long drives to clear the DPF - time which I will never get back and I now regret.

Alas, whilst I never had a DPF issue because of my efforts, all those Active Regens I had to do took their toll on my engine and most likely through oil dilution (possibly also the frequent high temperatures) my engine started to make a rather unpleasant knocking, most likely the crank.
If you are determined to get a diesel then I strongly suggest doing a lot of research on Passive Regen, Active Regen and Forced Regen because I don't think your journeys are anywhere near compatible with a DPF and you could end up wasting a lot of time and money like me. I got rid of the car and bought a petrol and despite being a V6 supercharged (and AWD) I'm actually spending similar in fuel but now I'm not having to waste hours of my life doing needless DPF runs. Besides, a petrol sounds so much better! lol
Hope this helps and good luck.

Out of interest (and being a nosey barstered) - what was the diesel car you had, and what are you driving now?Edited by ritch on Wednesday 1st September 17:29
