Fault codes P2500–P2599
P25xx codes mainly cover: battery, charging and glow plugs, turbo and boost pressure, engine computer and electrics. Our list has 62 codes in this range. With most of them you can drive gently, but get the car checked soon. Repairs cost roughly €30–1800, depending on the fault. The most common are P2501, P2502, P2503.
