The four things that set the price
| Factor | Why it matters |
|---|---|
| How many modules hold the figure | An older car may keep mileage in the cluster alone; a modern German car cross-stores it in the immobiliser, body computer and beyond. Every extra location is real work — and skipping one isn't correction, it's a mismatch waiting to be found. |
| Make and model year | Some clusters open up over the diagnostic port in minutes; others need direct EEPROM work with the cluster on the bench in the van. Newer platforms with locked gateways take specialist routes. |
| What's already been tried | Recovering a corrupted cluster after a bargain OBD tool costs more than doing the job right once — there's diagnosis and repair in it, not just correction. |
| Where the car is | We're mobile from Leatherhead (KT22). Core London and Surrey territory is standard; longer runs are quoted honestly for the distance. |
What the price never depends on: urgency games or what a call handler thinks you'll pay. The quote comes from the car, and it's agreed before the visit.
Why "cheapest" often costs the most
The bargain end of this trade is a one-plug OBD write to the dashboard. On a car that stores mileage once, fine. On most cars this decade, it leaves the cluster saying one thing and the immobiliser or ECU saying another — a red flag to any diagnostic scan and, on BMWs, a literal red tamper dot. Then the job gets done twice.
Our rule is boring: find every place the figure lives, update them together, verify, leave. Once.
