thermal reactor service light

[benmcgill]

The reactor is long gone, but recently the "reactor service" light came on ... does anyone know how i can reset the interval switch?

WTF is a thermal reactor? Is that like a flux capacitor?

No, no no... BMW had these things in the cars in 75 onward for emissions (as I understand it) in the US. Not sure how it works.

I don’t believe 02s were ever equipped with OEM flux capacitors.

I believe that the thermal reactor is a small thrust generator that was installed in the last couple 2002 model years to provide alternate energy boosters to offset the HP robbed by various smog devices. It is powered by a “permanently sealed” thermonuclear power cell.

Use this link to reset the service light.

Easiest way is to just take a small phillips screwdriver and take the cover off of the light and unplug the connector. Or you could get fancy and wire in some turn signal indicators in it's place.

The answer is there. But realy there should be a little box under the brake booster suport against the firewall the spedo cable goes through it, there is a reset button on the box.

Follow the speedo cable from the firewall. The cable goes to a box with a button you can push in with a screwdriver. Push in and the light resets.
