Daf are real anal with it last one was a Euro 6 LF that kept bringing on the oil breather system warning as there not allowed to put oil fumes to atmosphere. Turns out cylinder 5 had worn out rings. The trucking was knocked off the air filter housing so it was sucking in dusty air which basically shot blasts the cylinder and rings. The oil sample results even showed metal traces from the valves
