Odometer showing ellipsis/dashes instead of digits

Symptom reported on a 2018 X80: the odometer stops showing digits and displays an ellipsis ("...") instead ¹. Possible causes discussed by the community, in no particular confirmed order: a damaged odometer/speedometer cable (on cable-driven variants), mechanical wear in the mechanism, an electronics failure in the digital odometer circuit, or — more concerning — a sign of tampered/rolled-back mileage; checking whether the battery clamps had recently been disconnected was suggested as one diagnostic angle ². In this specific case, however, the issue traced to something much simpler: the owner had just reset the daily trip counter, and doing so was what triggered the ellipsis display — not a hardware fault at all ³. Consistent with that benign explanation, a full diagnostic scan with a Launch-brand scanner on this car found no odometer-tampering indicators and only unrelated tire- pressure-sensor errors, with total mileage still readable through the scanner throughout ⁴⁵⁶. Practical takeaway: before suspecting a mechanical/electronic fault or worse (odometer fraud), check whether the display glitch coincided with a trip-counter reset — this alone reproduced the ellipsis display in the reported case, and it recovered without any repair.

Mechanism confirmation: invalid cluster-memory checksum after battery disconnect. Consistent with the ellipsis/dashes symptom this card already documents: after a battery disconnect, the odometer can display dashes instead of a mileage figure because the checksum stored in the instrument-cluster memory becomes invalid. The fix requires reprogramming the correct mileage value back into the cluster's memory chip using a microcontroller programmer (an ECU-tuner-type device) — this is specialist work, not a user-level reset. The mileage figure is stored separately from the fuel-economy/consumption calculations, so this fault does not affect trip-computer readings ^{78910 11}. Disputed dealer pricing: some owners report official FAW dealers quoting 3,250–5,200 RUB (RU market, as of July 2024) for this fix, but without any guarantee that the dealer actually understood or addressed the root cause — a point of friction/disagreement in the community about whether the dealer price reflects real diagnostic work.
