Should the engine mangement light come on, you can read most issues through the OBD port using a suitable code reader. More information can be found on the relevant pages for your particular smart: fortwo 450, fortwo 451 and Roadster. Should your code reader simply give you a fault code, please use this system to look up the description, possible cause and resolution where available.
Please use this system to look up OEM smart part numbers. Each code was correct at the time of adding. However, we cannot be responsible for any parts that have become obselete or removed by smart. Should you spot any mistakes, please let us know via the contact us system.
If you are looking for a particular part number, please contact us with your VIN and as much detail as you can. We will look up the part number and get back to you. :)
