Fault codes P2400–P24FF
P24xx codes mainly cover: diesel particulate filter (dpf), egr valve, tank venting and fuel vapours. Our list has 90 codes in this range. With most of them you can drive gently, but get the car checked soon. Repairs cost roughly €10–1500, depending on the fault. The most common are P242F, P2452, P2453.
