Re: GT - Loss of power
"Thanks for the reposnses guys but I'm not very car savvy. When you use acronyms like MAF, DPF and EGRV I have no idea what you're talking about."
My (limited) understanding is that over the last few years, new stuff has been added (DPF's etc) to diesel engines to stop them chucking out so much soot & muck. Fine, but the problem is that on a very simple level, they are just kinda filters, & they get clogged up, with the very stuff they are designed to take out of the exhaust. They go into "regeneration cycles" to burn off all the muck, & if this doesn't happen, you lose a whole load of power until such time as the re-gen can be sorted. The frequency with which the regen is needed is dependant on type of driving done. If you do loads of urban driving, the clogging up is worse. I do find this a bit ironic, as diesels have become more accepted for better mpg driving, so there are lots of people who use a diesel engined car for town driving, which it was never really good at/designed for. If you do a fair bit of motorway driving, that gives the best chance of letting the car regen when it needs to, which is normally done by driving for a few miles at a constant mid-range speed.
If I'm not totally accurate on this, I'm happy to stand corrected.
