My son drives a Ford Transit year 2011. Running power approx. 288,000 km. Engine was replaced after 120,000 km. Last year the turbocharger was renewed, the Russian particulate filter was renewed. On the way from Portugal the car stood in the workshop and the AGR valve was replaced, as the engine control light no longer went out. The car is absolutely normal, only the lamp is constantly lit. Now also the differential pressure sensor was changed. but the error cannot be deleted. The friendly meant that can be basically anything, cable breakage, ECU etc. Someone has an idea. I am grateful for every idea. The error code is P2463 Lg Sandra
