Quick Fit Check — before you order
Match the complete OE number, all four terminals, connector latch and mounting profile to your original switch. A vehicle name alone does not confirm compatibility. Send your VIN, original OE number and old-part or connector photo for fitment support.
Catalogue-supported Smart applications
Selected Smart Fortwo Coupe and Cabrio, model series 451: 1.0 petrol, 1.0 Turbo, Brabus and 0.8 CDI versions. Vehicle production dates and regional model years differ; verify the chassis/engine variant and original OE before ordering. This is not a listing for every Smart or Mercedes-Benz vehicle.
OE and catalogue references
Primary OE: 4515450109 (also formatted 451 545 01 09 / A4515450109). Catalogue comparison numbers: 4515450209 / A4515450209 and 4525450009 / A4525450009. These identify the replacement reference family; compare connector and mounting before substitution.

Questions before ordering
How do I confirm fitment?
Compare the original OE, connector, four-terminal layout and mounting. If any differs, contact us before ordering.
Is A4515450109 a different part from 4515450109?
The catalogue lists both formats in the same reference family. The prefix or punctuation alone does not confirm vehicle compatibility.
Are 4515450209 and 4525450009 related?
Both are listed as comparison numbers in the manufacturer catalogue. Use OE and physical checks together rather than vehicle name alone.
