Aiways U5 fault codes

The Aiways U5 has no ongoing dealer or manufacturer support left in Europe, so a warning light usually ends in guesswork. This index covers the codes we are asked about most — what the code means, whether the car can still be driven, what to check first, and which parts are involved.

Drive guidance below is a deliberately conservative summary. Always confirm with a diagnostic tool and a qualified technician.
