How to match Smart engine control units by part number

When replacing an ECU on Smart cars, the numbers on the housing matter most. A similar case or the same car model does not guarantee compatibility, so compare the full numbers and the control unit family marking.

Numbers and markings of Smart control units

Smart control unit numbers usually consist of the electronics manufacturer's number and the OEM number. Enter both in the shop search or send us a photo of the label. Enter the number from the label once without spaces and once with spaces or hyphens, as both notations are in use.

Examples of Smart control units

Control unit preparation options

A used ECU holds the data of the previous car, so some models are also sold as IMMO OFF or VIRGIN versions. Details: ECU preparation options.

Why Auto24Parts

  • Matching by numbers: listing names contain the part numbers from the label, and if in doubt we check compatibility from a photo of the label.
  • Used parts come with a warranty; its terms and period are given in the listing and on the returns, warranty and complaints page.
