not when the same problem and solution keep repeating
I hear what you are saying and I totally agree in respect of petrol engined vehicles but didn't assume that the same necessarily held true for diesels. The addition of the DPF clouds the issue even more as I have heard conflicting advice from well informed sources.
One school of thought suggests that cruising at a steady speed of 60-70mph for a few miles should regenerate the DPF and others (yourself included) are advocates of using higher revs in all the gears as the best method of increasing the exhaust gas temperature to achieve the same end.
Perhaps a combination of both might work, changing gears at higher revs around town and maintaining a steady, relatively high cruising speed on open roads might be a good compromise.
