Regarding removal of the DPF

Are you talking about the Euro emissions levels or what is required for passing an MOT?

The Euro emissions levels which are a requirement for a car being allowed on the road.

For example the London LEZ. If you've a commercial vehicle (even a van) which doesn't meet the Euro 3 then you can't go into the LEZ without it costing you £100's per day.

Dont you think that the solution to the whole expensive DPF / regeneration / replacement thing is for manufacturers to devlop a cheap disposable replacement filter that gets replaced at every service interval?

How would that work? How would you have "cheap" included in something which had to be a sealed system?

DPF is a good solution far better than bloody Adblue.

No, they reduce PARTICULATE emissions.

So you have the time to be pedantic but still haven't told us how you know that all cars that have had their DPF removed would fail a VOSA roadside emissions test. Do you plan to give us an answer on that anytime soon or can we assume that you have made a sweeping statement that you have not been able to substantiate?

I'm referring to post 21 just incase you might have selective amnesia

But that is just a requirement brought in for London. A euro 3 compliant vehicle can still be used in the rest of the UK without having to pay the charge.

How can it be a sealed system if it is designed to have a set life and to be replaced?

If you remove DPF, it is a modification and may void your insurance.

I don't understand why you need to do this in the first place? If you buy a diesel and do enough mileage you should never face DPF problem. If you are facing DPF problem, then your lifestyle is not suited for diesel car.

Just get a petrol car then.

Otherwise, what's the point in having them?

To certify a car for sale in the UK - I don't think it's required to drive one.

Once a car is registered, you can pretty much do what you want to it, so long as it remains safe and roadworthy; will pass an MOT; and you declare it to your insurance.

For example if you want to take an old Rover, move the front seats into the back to turn it into a 2 seater, then install a 27 litre engine, you are absolutely fine.

Yep the DPF is in the exhaust system, and gets in the way of the engine 'breathing out'. Removing it lets the engine breathe easier, work more efficiently, and will have more power and better economy.
But the DPF traps all that black soot that you used to see coming out of diesels - do you actually want to continue putting that crap into the air? Oh dear!
See also - removing the catalytic converter - this is in the exhaust system and gets in the way, if it's removed you'll again get better economy and performance because the engine can breathe better. But you'll be polluting far more in this case.
