I have cleaned the egr and it was springing back and sealing nicely, all sensors cleaned, I do need to do a smoke test though and look at injectors.
The idea is not to remap it, but the mechanic can have a mapping specialist look over the current map to see if it's been done poorly previously. It only blows a cloud of black smoke at 2k or so in the higher gears if I put my foot down, hence us thinking it's overfuelling at certain RPMS etc.No other noises or running issues, that's why we don't think it's a leak or sensor, but not completely ruling it out.
