If a tester has difficulty identifying a gutted DPF, then what chance do you think they have of spotting a vehicle has beeen re-mapped?

A dealer will know the moment they put a diagnostic tester in. Try reading the whole of the post properly. If you remap a car, you are potentially invalidating the warranty and people advising others to risk their warranties if their remap is picked up by dealers and saleability of cars if they have advisories on their MOT for potential fiddling with objects that are legally mandated to be present is irresponsible.

You do also realise that loss adjusters are paid commission on what they save their clients in the insurance offices, don't you? If they decide they could decide that the car was adapted without informing them which potentially voids their insurance. Remapping also counts as a modification that has to be declared.

Because I don't really care

Gut your DPF if you want

Just don't come back crying when you have an Insurance claim denied when the loss adjuster spots the vehicle doesn't comply with C&U Regs.

Neither the 370Z nor the Clio 197 have DPFs.

I've never owned a car with a gutted DPF.

The point at hand was that you said a car with a gutted DPF would fail MOT.

This is NOT the case, however you seem to have a problem acknowledging you are wrong

Do you believe everything you read in The Guardian?

Actually having quickly skimmed that article are you sure you read all of it?

I dont read the guardian at all. It was a link from a thread on Pistonheads.

I imagine it would be very easy if the dealer attached their diagnostic computer to the car.

Unless its a specific diagnostic computer for that specific car it would be very hard to tell.

Diagnostic computers tell you values of sensors within the engine, they dont analyse the code within the ECU.

No, they wont know the moment they plug a diagnostic tester in. They'd have to do quite a bit of analysis to prove it.

So you have an accident and the loss adjuster comes out.

He has 30 mins per car to review the damage and write up a report.

Is he really going to take the exhaust off and see if the DPF has been gutted?

And is he really going to take out his computer, log on to the ECU and start to analyse the code?

And to answer that - no, it doesnt happen.

Likewise DPF - it would affect related parts, but not all parts. The dealer / manufacturer for example, cant decline a gearbox failure because you've taken a filter out of your exhaust.

So you'd be happy to personally indemnify any poster that follows your advice in case their car gets written off and then they don't get a penny?

If you're not prepared to indemnify them, then your 'advice' is irresponsible.

Not sure why you think that. The diagnostic computer will probably run a checksum test on the ECU and any changes will be immediately apparent. Also any live data from the car will immediately show anomolies in the pressure readings either side of the dpf and probably the temperature readings too. It would be obvious IMO.

Dont be ridiculous.

I am giving information concerning the current rules and regulations , not advice on what to do.

People are given information, and they can make up their own minds or do further investigation if required.

Your "oh oh the insurance company will take your car apart into its component bits and try to identify and non conforming parts" is frankly ridiculous, thus i gave the correct information.

A checksum test only shows invalid or corrupt lines of code, not changed lines of code.

And are pressure readings even taken either side of the DPF? And whos to say what the readings should be for each specific engine / model / BHP / year combination of every car ever made?

Exactly, a checksum will be used as a security measure and will show the software has been tampered with. Finding out what changes have been made would need some investigation but reflashing the software back to factory spec would soon show a few fault codes.
