Fault codes P0800–P0899
P08xx codes mainly cover: automatic gearbox, engine computer and electrics, battery, charging and glow plugs. Our list has 99 codes in this range. With most of them you can drive gently, but get the car checked soon. Repairs cost roughly €40–2500, depending on the fault. The most common are P0801, P0802, P0803.
