Aiways U5 and U6 problems: find the guide for the fault you actually have
This page is the map, not the manual. It tells you which guide to open for the symptom your car is showing — grouped by what you actually notice, from a car that will not start to a tailgate that stops halfway. Every page behind these links carries our own assessment and says where it comes from, so you know how far to trust it before you act on it.
Two things are true of these cars in Europe and they shape every page here: the manufacturer network has gone, and much of what looks like a fault is either one simple cause presenting itself many times over, or a service that was switched off rather than a broken car. Start with the symptom. If you already have a fault code, the Aiways U5 fault code index is often the faster way in.
Power and starting
The car will not start, or it starts and then behaves as if everything has failed at once.
- Every warning light at once, and the car will not start A flat or failing 12 V battery browns out several control units together, so one undervoltage condition is reported twenty times. Read this before you buy a battery — the order you check things in matters.
Charging
The car will not take a charge, or it stops charging on its own.
- DC fast charging fails, charging stops partway, or the charge flap will not open DC-only failures point at the handshake between charger and car; a failure on both AC and DC points somewhere else entirely. Splitting the fault the right way is the whole job.
Body and openings
Something on the outside of the car will not open, close or lock.
- Power tailgate stops halfway, or the locks misbehave A tailgate that opens partway and stops is often a lost learning value rather than a broken strut. Covers what each symptom points to and when it is a part.
- Flush door handle will not extend or retract The most reported failure on the U5 in the European owner community. How to work out whether the handle is even the fault, and what to send us if it is.
Collision and appearance
Damage to the outside of the car, and the version question that follows it.
- Bumper, headlight or wing to replace A U5 bumper is not one part — surround-view camera, parking sensors, blind-spot radar, kick sensor and plate bracket each change the version. How to confirm which one your car takes.
Diagnostics
A warning light is on and you want to read the car yourself.
- Reading and clearing fault codes on a U5 Standard powertrain codes are readable with a generic OBD-II tool on this car. What a generic reader can and cannot reach decides whether an empty scan means anything.
Chassis and running gear
Noises, wear and inspection failures underneath the car.
- Knocking from the front end, or a failed inspection Worn stabilizer links, control-arm bushings and ball joints are ordinary parts, and the repair is routine — the difficulty is that no Aiways network is left to do it. What to check and what is involved.
- Tyre and wheel sizes, pressures, TPMS The two factory wheel and tyre combinations, the wheel bolt torque, and exactly what the tyre pressure warning means. Where the manual is silent we say so rather than invent a figure.
Service and consumables
What actually has to be replaced, and when.
- Service schedule, fluids and wear limits An electric car has very little on a mileage clock: three fluids at three years or 100,000 km, everything else inspection. The catch is in the method, not the interval.
High-voltage battery
Range has dropped and you want to know whether that is normal.
- Battery health and state of health (SOH) The car estimates state of health itself and stores fault data. The useful question is whether your range loss is slow ageing or a fault that arrived all at once — this page separates the two.
Connectivity and the app
The car and the phone have stopped talking to each other.
- App will not connect, no mobile network, SOS light flashing Most of this is not a fault you can repair — it is a service that was switched off at the manufacturer end. Keeping the two apart is what stops you spending money for nothing.
Ownership and running costs
Keeping the car identifiable, repairable and on the road.
- Worried about spare parts after Aiways left Europe The official channel is largely gone but the cars are not orphaned. The routes parts still reach owners through, and why your VIN and OE number are the two things that matter.
- Buying or selling a used U5 When there is no brand support left, the question that decides the deal is not the price — it is whether the car can still be identified and repaired. What to check on both sides.
Reference — reading numbers and rules
The background pages you need once you know which part you are after but not which number to ask for.
- How Aiways part numbers are structured Prefix, base number, version letter, colour or export suffix — reading the structure is how you order the right letter the first time.
- Aiways colour and trim codes Why the same interior part carries a different number ending -CM02 or -CM14, and why that is not a paint code.
- Why one part has several OE references How an old and a new Aiways number relate to each other, and why the same physical part can carry more than one reference.
- Shipping restrictions on Aiways parts Lithium battery components, gas-filled struts and pyrotechnic devices each carry a different air-freight rule. Knowing the class before you order avoids surprises.
Tools
Where to go next with a code in hand, or when you are ready to ask for a part.
- Aiways U5 fault code index (116 codes) What each code means, whether the car can be driven, and the parts involved. Start here if you already have a code in hand.
- Aiways U5 and U6 parts we supply The references we carry for these cars. Availability and price are confirmed per enquiry rather than published.
How to use these pages
Each guide is written to answer one question: what does this symptom point to, and what do I do about it? They are laid out so you can stop reading as soon as you have your answer. Where a figure comes from owner measurement rather than the manufacturer, the page says so. Where the manual is silent — rim width and offset, for example — the page says that too rather than filling the gap with a plausible guess.
There are no repair instructions here on purpose. The U5 and U6 are high-voltage cars, and work on the battery pack, the contactors or the safety systems belongs with a technician qualified for it. What these pages give you is enough to have an informed conversation with your workshop, and enough to order the right part.
On part numbers. The Aiways workshop manual identifies components by its own internal document numbers, which are not orderable OE part numbers. We do not present one as the other. If you need the reference that is actually orderable for your car, send the VIN and we will confirm it.
Not sure which page applies, or need a part? Send the VIN and what the car is doing — get in touch and we will point you at the right guide and confirm the part reference that fits.
