I SeaFoam'd my '02 R50 (90k miles) yesterday. Besides the requisite amount of smoke, the SES light also came on.

How can I reset the light? What might be the cause?

Thanks

 

You probably logged a misfire code, which can be read with a generic code reader.

That said; you don't need to Seafoam the Gen 1 engines, as the fuel is injected pre-valves, so it is cleaning them while the car is running.

In cars that aren't direct injection, Seafoam is a snake oil treatment when used in this respect. It can be used in the oil 300-500 miles previous to changing, and will aide in cleaning deposits.

the light went out last nite and has not come on since. Good to know that I don't have to SF the car anymore. Thanks!

 

There will be a stored code in the ECU, if you find someone with a code reader you can find out what it was.

The CEL goes away after 3 key cycles without the fault recurring.
