In regards to the fumey smell, it has settled down, I now only get a waft on cold starts really. It confirms for me there is a reason for the dpf and it does its job well in that respect.
I hope new cars have these little problems ironed out!

More information for those curious on the remap side of things:

Performance difference is considerable,  power band is wider, the car will now redline rather than top out at 4.5rpm,  the extra 500rpm equates to another 10mph in 3rd gear.

Torque is constant and everywhere, any gear or rpm, foot down and youre flying.

As a benchmark, my cousin in his bmw 328i couldnt pull away from me.

I've just realised my profile states my car is a 2011 car.
It's not, it's a late 2006 model.

Has the remapping affected the fuel consumption?

I am in same situation. My cherished 6 is immaculate, with 172000 on the clock. I have spent nearly 1 year trying to fix the dpf issue it has. Removal is an option I am considering.

Don't remove it. It will pollute even more than now. You will never know what the cowboy has done to the car. How can you guarantee that the fake input given to all sensors involved, will not cause a mechanical problem further down the line, or that your consumption does not reach astronomical levels?

Nowadays, non franchise, non chain, MOT centres cannot bother any less for the conditions of the cars. They pocket the money, cash, no receipt and there you go. I have come across cars on the motorway that smoke worse than the flying scotsman in front of police cars and nothing happens. It is all about having a piece of paper stating that your car is fine.

The new MOT test looks explicitly for DPF tampering.

A bloke at work has been caught out already. His garage that has overlooked this mod for years will no longer do so.  He wasn't a happy bunny.

It was always like that, but hey, nobody checks. I was at the ATS for new tyres before the MOT and they had a huge poster that they will refuse to MOT a car with unknown service history because the new MOT procedure adds such stress to the engine that the timing belt can go. So they were requesting proof of timing belt history otherwise they would not proceed. I have not seen this in a small garage.

But as you say, even with such notice, there will be garages that will check it out. On the other hand, it is so silly. People who have DPF problems, get some low mpg, plus being illegal, that buying a petrol car, will not only make them legal and will help them to avoid all the DPF removal costs, but they will get better mpg. I have no idea what motivated them to keep the car, remove the DPF and they did not part exchanged for a petrol one that will make them more money. At least now with the MOT, some of them will go back to petrol.
