Fault codes U0100–U0199
U01xx codes mainly cover: module communication. Our list has 53 codes in this range. With most of them you can drive gently, but get the car checked soon. Repairs cost roughly €60–800, depending on the fault. The most common are U0100, U0101, U0102. Based on AI combined with our hands-on workshop experience and knowledge.
