Diagzone diagnostic software support: Diagzone (Fawcar file) added FAW X80 support in a 2017 file-version update that became broadly available around April 2024. Recommended hardware: a Mucar BT200 adapter running Diagzone firmware, or a similar compatible OBD2 adapter — a generic OBD2 scanner alone is not enough; the launcher hardware is still required. Software can be purchased per-model (example price cited: 720 RUB (RU market, April 2024) for a single model file).¹²³⁴⁵

Cruise control retrofit (base-spec cars): cruise control can be retrofitted on base ("бомж"/budget) spec X80s that lack it from the factory, using (1) aftermarket cruise-control button switches and (2) the Diagzone software once it added REST/facelift support. One owner successfully activated cruise after dealers and independent Avito specialists initially refused the job — DIY testing over a couple of days proved it feasible. Cheap button kits are available from generic online sources.⁶⁷⁸

Cruise control — real-world usage feedback: owners report cruise control is only useful on long highway stretches (18+ hour drives); it is ineffective in stop-and-go traffic or on short city trips. Some flag a safety concern on rural roads — drowsiness risk — and suggest a speed limiter would be more useful than cruise control for highway safety.⁹¹⁰

StarLine A93/A96 remote starter: the StarLine A93/A96 (equivalent to the A39 series) remote-start system offers roughly 200 m range with no obstacles; hold the button 5 seconds to send the start signal, with ~15 seconds for the feedback signal to reach the key fob. Manual- transmission cars require a multi-step start procedure (not detailed here); automatic-transmission cars use a simpler procedure. The A96 is reported as reliable on the X80; installation quality issues (wiring errors, incorrect fuse routing) have been reported from generic/non-specialist installation shops.^11121314

ABS behavior on steep/sloped terrain: when the vehicle is high-centered or tilted at a severe angle (off-road use), false ABS activation is possible — the system is designed for normal on-road driving angles. Community reports say the vehicle levels out and ABS stabilizes once all wheels contact the ground normally. (Low-confidence, single-report observation.)¹⁵
