This is an interesting post, my view on this one is similar to Peter's
I look to repair a fault to Manufacturer standard and removing DPF's is just a bi-pass, it isn't the correct repair .
Customers do lean on us for the "Cheap" repair and as long as there are people out there bi-passing & re -mapping customers will look for that service.
I offer a repair(new DPF) and not a bi-pass as it's the correct repair to carry out.
Is it legal or not ? I'll leave that to the politicians and Vosa to sort out and the thousands of DPF's that have been bi-passed by garages making a quick buck for the easy work and are the customers hero for saving them hundreds of pounds as That rip off garage along the road wanted to fix the car properly .

These same customers that were very pleased you saved them hundreds will not remember this when they fail the next MOT.
I'm not saying anyone on this forum are involved in the quick fix but those who have been might be worried of the pending outcome.

Just a thought for those that are bi-passing DPF's , i would trust you wouldn't have your kids in the car if you smoked for obvious reasons, so then for another obvious reason why poison your kids with particulates ?
