Where Vauxhalls store the mileage
GM-era Vauxhalls (Corsa C/D/E, Astra H/J/K, Insignia, Zafira, Vivaro) split the story between the instrument cluster and the body control module, and the pair are expected to agree — a swapped cluster or a one-plug write leaves them arguing, which surfaces as warnings or a rejected figure. Correction here means both ends brought to the documented total together, then verified. Where a swap has upset more than mileage, our module replacement service picks up the rest.
The Vauxhall bread and butter
Used clusters from breakers programmed to true readings — far and away the top job, because these dashes fail often enough that swaps are routine and repair isn't always offered locally. Then Insignia and Astra corrections after BCM or cluster work elsewhere left values mismatched, and Vivaro vans — shared with Renault Trafic underneath — sorted at the yard between jobs.
Models covered
Corsa C through F, Astra H through L, Insignia A/B, Zafira, Meriva, Mokka, Crossland/Grandland and Vivaro vans. Call with the reg and the reading it should show — usually bookable within a day or two.
Whatever the reason — replacement cluster, import conversion, post-repair tidy-up or a rescued DIY attempt — the standard is the same: every module in agreement, verified at your address. Cost questions? The cost guide explains what moves the price.
Corsa E — breaker's cluster, 39k showing, 71k true
A first-car Corsa got a used dash after the original's display died. We programmed the documented 71k and settled cluster and BCM into agreement on the family driveway — twenty minutes, done, MOT history intact.
