Hello, I have a problem with blue smoke and can't get rid of it.. If any of you guys could help me to find out whats the problem I would be really thankful. Already changed high pressure fuel pump, injectors, the car doesn't have nor dpf filter nor catalytic converter. I plugged my obd to check and it gave me 4 faults P0047 - Powertrain, P2263 - Powertrain Turbo/Super Charger boost System performance, U0301 - Network, P0380 - Powertrain Glow Plug/Heater Circuit "A". The car doens't smoke on higher rpm above 1500, it usually starts smoking when slow driving and on low rpm between 1000-1500. Also now it's driving way slower then usual. Could it be that it's a turbo problem ? Or can it be that the program of my ecu is bad ? In the past when I got rid of dpf and catalytic converter they programmed them out, but there's a chance that someone messed up the program.
Really need help on this!
