It's the "**** everyone else, I'm-alright-Jack" attitude I suppose.
I don't think this is the case at all, personally.
The DPF concept to me is rather flawed. They have been introduced and developed by vehicle manufacturers as a method of reducing vehicle emissions and keeping taxation as a result of emissions to a minimum - mostly because that is a headline that sells cars. Fair enough there are laws governing such things as well but its the money and numbers manufacturers really want!
If the DPF solution worked, people wouldn't mess with it.
There will be some people out there that remove the DPF purely on a performance basis to remove that last little bit of restriction from the exhaust and gain a little bit more power, but people with that mindset will continue to do this until the world stops turning, that is their choice.
I personally feel that most people remove their DPFs because they're causing problems with vehicle running. DPFs only work on cars that are regularly run on a good, high speed (not illegal, I mean motorway) high temp runs when temps in the DPF build up and it works effectively, but for mums on the school run or nipping to the shops 15 mins down the road or whatever the thing is barely up to operating temp so it is never going to work effectively.
Regardless of our daily commute or how kind we thing we're being to our cars and DPFs, we've all done a run to the shops or the Friday night run down the road to the chippie, so you are going to clog your DPF to an extent.
How many times has anyone here been asked by a dealer what you intend to use the car for and been advised against buying a car with a DPF if you're only running around town? it doesn't happen.
Worse still is the regen process scares the crap out of people. We've all seen the posts of people saying OMG my car started to run like crap and smoke a lot so I turned it off quick but it was okay after that. Folk don't get it and why would they, they've never been educated about this kind of stuff so don't understand what was happening. I'll admit it's caught me by surprise a couple of times when I've gone into regen.
I get that we need a solution to remove the muck from diesel exhaust but the DPF is too clunky a solution to work and if it causes problems what is the simple and most effective solution to the problem - get rid and it'll never cause you a running issue ever again?
Can't blame folk for taking the permanent fix rather than sticking a bandage on it given the option.
