How Ford cluster numbers work
Ford part numbers follow PREFIX-10849-SUFFIX — 10849 is Ford's part-type code for instrument clusters. The prefix ties the unit to a platform and era (and the Visteon-built units often carry a VP prefix on the label too); the suffix tracks spec variants. That's why searching your full number finds a maze of listings — but the prefix alone tells you the family, and the family tells you the fault.

Whatever the family: the repair happens at your home or workplace, your original unit and mileage stay, and nothing needs programming afterwards.
Typical call-out
Booked by prefix — Dorking
A caller read '4M5T-10849-FS' off an old invoice. That one prefix told us the exact board and likely fault before we'd started the van. Repaired on his drive in Westcott next morning.
Common questions
Part number questions
Where is the part number on my cluster?
On a printed label on the cluster's rear casing — visible once the cluster is out, and sometimes via the top of the dash aperture. It follows Ford's pattern XXXX-10849-XX. If you can't get to it, just tell us the model and year; that's normally enough.
My exact number isn't listed — can you still repair it?
Almost certainly. The suffix letters change constantly with spec (fuel type, market, display); the prefix identifies the family. If your prefix matches — or you're unsure — call with the model, year and symptoms.
Do I need to quote the number to book?
No. It helps us arrive with certainty, but model + year + symptoms identifies the cluster in nearly every case.
