My cooper D had a tampered with DPF on it when I got it, I didn’t know at the time until it was up on the ramps for the tracking time be done, it failed it’s MOT last month because of it so I had to refit a replacement, luckily i managed to pick up a cheap one in advance as I knew it would fail because of it

worth a look around, I paid £150 for mine used as I got it the same time as the used exhaust off the same car, a quick ebay search brings them up at around the £180-200 mark which isn’t too bad really to ensure that the car will pass further MOTs

To be honest I really don’t know if the software has been adjusted by the previous owner as the car throws out some serious black smoke as if it’s still trying to regenerate every so often but into a hollow filter, the car had a joke straight through exhaust fitted when I got it and the cat/DPF had been tampered with so I think he had just had the inners removed for ‘performance’

To be honest I’ve yet to fit the replacement so it’s really going to be a case of seeing what happens when I do as to whether I get any dash lights or black smoke etc, if I do then I will hopefully find somewhere that can reprogram it back to stock

Most people that remove them don't bother with the software delete side of it as the change is done out of cheapness.

which is exactly what I suspect with my car!

while it’s up in the air I’ll also check the additive bag situation out

Like my arse after a curry

No, I never had it go into limp mode at all either with or without the DPF fitted

as a post script to this, I took the car to carsorbikes after I’d refitted the standard cat and he reset everything using his expensive reader, as I say we didn’t really know if it had been deleted so it was a bit of an anxious moment waiting to see if it would throw up faults etc but after the reset it was fine, the car ran the same so we came to the conclusion it was never actually deleted in the first place

Well I never had any issues before work after the swap but I’m not a mechanic and I don’t know whether mine has properly been deleted out when I got it so I wouldn’t take my advice and experience as gospel!!
