What's on your M-plate?decode the factory option codes.
Every Beetle left the factory with a run of M-codes stamped on its ID plate, recording everything from engine spec to export market. Enter the codes from your plate and we'll tell you what each one means.
How to read an M-plate.
On most Beetles, the plate is riveted to the front firewall in the trunk/frunk, usually visible above the spare tire once you pop the lid. On some model years it's on the driver-side door jamb instead.
VW reused M-code numbers across the Beetle's 40+ year production run. Where a code meant different things in different years, we show every documented meaning we found so you can match it to your car.
The same plate also carries the chassis number, engine number, and a paint/upholstery code string. This tool decodes the M-code options list only.
