A4 DPF Removal


New member
Has anyone removed a DPF from a A4 B8 2.7tdi, looks like a reasonable amount of work to get it out.
Any tips would be appreciated
I've had the DPF removed from my A6 2.0tdi, had to leave the car with the garage overnight and had to return several times due to them trying to remap the ECU to account for the DPF being removed, I think it was so that the light didn't come on. Anyway, got it sorted eventually after I insisted that my previous mapping was to put back on. Car runs fine now but chucks out loads of smoke when idling sometimes and definately when accelerating.
