Hello everyone I just joined group, have a 2018 eco diesel that I deleted over a year ago. Recently had a P04DB code come up and shut down the turbo. I cleaned throttle body (didn’t really need it) replace the manifold intake MAP sensor, deleted the code, but after 10 km drive code returned. couldn’t find any air leaks ANY IDEAs.

My problem ended up being a transmission tuning issue. Had to reset clutch values a few times but that code isn’t for a map issue it’s for the crank case vent system. Do you have a oil catch can installed?

Could be the sensor bad, can’t remember what year they did away with it… if you had one it would be front of drivers side on the head with a 5/8” rubber line coming off it and going back to your intake tube preturbo. Could have came loose from that connection or at the sensor itself. Or oiled up and can’t read the pressures
