A friendly hello to everyone. I have a problem with my Renault Trafic box bj 2010 212000km 2.5 cdi. A few weeks ago the gearbox broke. So I installed a new one since then the engine can no longer be started. Jumps briefly and goes out immediately. After testing all plug connections and diesel line I got a mech that could read out the errors. It is always defective injection. He tried to delete the error but no success. but it showed too high injection pressure during the start process he said I have full pressure when starting as at Vollast therefore the engine constantly shuts down. His suggestion change real sensor. Now I have made no success. Maybe someone can help me here. Thank you for your efforts. Mfg chris
