Question 1

What are the symptoms of a failing Belts & Pulleys on a T1N Sprinter?

Accepted Answer

Chirp or squeal on cold start that fades as the engine warms Rattle from the front of the engine at idle, quieter under load Belt edge fraying, glazing, or dust building up behind the pulleys Battery light flickering at idle as the belt slips on the alternator

Question 2

Which fault codes point to this T1N Sprinter repair?

Accepted Answer

P0562: System voltage low — a slipping belt underdrives the alternator. P0521: Oil pressure sensor performance if the drive has affected the pump. Confirm with a scan tool before ordering — codes narrow the system, not the exact part.
