No DPF, no MOT.

So making your car illegal and declaring it is ok ?

In terms of insurance cover, yes as long as they accept the modification.
Strictly speaking any changes to the exhaust system are illegal, however there's thousands of cars & bikes in the UK running aftermarket exhaust systems who have accidents and there's no problem with the insurance side of things as long as it's declared at the time.

, removing a DPF is illegal so your insurance will be invalid , not much good if you have a life changing accident and get no payout

As i've already stated, it doesn't make the insurance invalid.

If you disagree, call Adrian Flux or Sky insurance who both cater for modified vehicles and they'll tell you the same.

Seems odd that its ok to insure a car that can fail a MOT

According to the government website its illegal seems they must me wrong then ?

Some firms offer services to remove the filter, claiming it will improve the economy. But it is an offence to drive a vehicle that has been modified this way, as it will no longer meet the emissions standards the car achieved when it was approved for sale in the UK

You can fail an MOT for having a cracked windscreen. Remove the windscreen and it will pass. Drive it on the road without a windscreen and you'll be breaking the law
Passing an MOT, being road legal and having valid insurance are all 3 separate things.

Having an MOT doesn't mean the vehicle is road legal
Having valid insurance doesn't mean the vehicle is road legal
Having a road legal vehicle with MOT doesn't mean it's insurance is valid

they also have to change the ECU settings, so this along with removal will invalidate your insurance

Out of curiosity, when was the last time you had an accident and the assessor came out and took the exhaust off to check either the DPF or CAT had been removed, OR brought enough diagnostic equipment and tools with him to strip the ECU out of the car, connect it up and compare it to the standard ECU programming on the car?

Dont know what they check, but they are always looking for ways not to pay out, people are taking these off probably not aware of the risks.

End of the day its illegal not to have one fitted so by definition your car cant be legal can it

If they're going to pull your car physically apart to find a reason not to pay out, they'll find a reason not to pay out anyway, whether it be a tyre at the wrong pressure or some bulb out.

A DPF removed on a car wouldnt be worrying me, at worst if it is picked up at MOT, then you simply get it refitted. Simples.

For the record, my car has a DPF, and i've no plans to remove it.

Again, where has anyone said it is legal?
You're stating something that no one is disputing.

When my last car was wrote off, it had an aftermarket exhaust (strictly speaking this is illegal - but not dangerous)
I informed my insurance company of the modifications and when it was wrote off no one tried to dispute paying out.

Same again on my current vehicle. It has an aftermarket exhaust with the cat removed.
This isn't an MOT fail and it doesn't invalidate my insurance since it's declared, but by the word of the law it's illegal.

I don't get this, by this logic every car I've owned, modified or unmodified, was illegal.

For example my first car, an elderly Mk4 1.3 Ford Escort, would have been illegal as the carburettor had seen better days and certainly wasn't performing as well as when it was new. No way was that car as clean as when it rolled off the factory floor.
