I think some posters are on a wind up. Millions of diesel car owners just drive their cars. They don’t get any of the issues described. They don’t drive around thinking “oh I must just drive down the motorway in 3rd gear”.

This fans running etc is something I get. Am I right that this is where the regen has started but didn't finish before the end of my journey.
Is it OK to leave it fans running?
Should I go out for another drive and if so how long is needed?
Yes Navver if the fans are running after you have turned off it was in hte middle of a regen the more failed regens the more possible issue you may have
funnily enough the daughter bought a used vauxhall 2.0 Antara on Friday , went to a wedding Friday night , and on there way home Saturday morning the dpf warning light came on . warned them not to buy vauxhall .
Euro 5 and Euro 6 diesels are fiendishly complicated and there is a lot to go wrong. A DPF clogging up is usually a symptom of another fault in the system.
My Ford Galaxy had a DPF that kept clogging but with no other error codes, it got worse over 2 years and eventually EGR errors started coming up. We replaced the EGR valve and then a fuel vapouriser near the DPF and finally it is all working again but at a cost of £1k. So in our case a faulty EGR was causing the DPF to block.
Well I have given in and traded the Insignia in for a Ford Kuga, lost a fair bit of money but just don't trust the car. Lets hope the new one fairs better.
Hi we had a Vx anatara for 3 years and never had 1 bit of trouble with it best car we have ever had. The issue with the DPF, is knowledge, ours used to do a regen every 550 - 650 mls, and that was with two good runs up and down the m62 each day.
You see all the old diesels accelerate in a cloud of black smoke well that is what the DPF is catching. The idea is that when getting near to full the DPF is injected with fuel to burn to soot off at a certain temperature, the problem being modern diesels and short journeys its not good you would be better off with a petrol vehicle. The down side is the fuel then dilutes the engine oil, hence the oil condition meter/ indicator.
You know when the Vx antara is doing a regen when you take you foot off the accelerator, and you MPG figure on the dash is low, or when you stopped the rpm was higher and Stop/start was disabled.
Got a VX insignia now, and this shakes with the higher rpm when doing a regen with the fans on, they should stay on after switching off and the regen, recommence once the correct temp is reached after a restart. But short journeys and not getting hot, is bad for modern diesels, pity they don't tell you this, although we were informed recently whilst looking for a new car ,and asked about our mileage and journey types with the DPF being sited as an issue.
