Fault codes P1500–P1599
P15xx codes mainly cover: idle and throttle, fuel and air, camshaft timing (vvt). Our list has 15 codes in this range. 2 of them mean you shouldn't keep driving. Repairs cost roughly €30–1800, depending on the fault. The most common are P1500, P1504, P1505. Based on AI combined with our hands-on workshop experience and knowledge.
