To be honest I am seriously thinking of returning the car but that will just be another headache.
I checked the prices of DPFs and they cost at least £300. If I add that to the cost of undoing the remap that should easily go past £600. Unless of course he is right that I need to change the injector nozzles or whatever he is talking about and the smoke will go away. I feel like it could take me down the rabbit hole and cost me far more than I bargained so maybe returning it is best so I can cut my losses.
I guess the question is Does remapping always lead to smoking if DPF is removed? Is there a way of easily checking that the DPF has been removed since there is no guarantee you can tell it's there in the first place? What did I get myself into? Kinda looks like BMW is actually starting to break my wallet and haven't taken it for a proper spin yet.
