If the batery has been disconnected or run flat these two lights stay on, even when there's no problem in the system. A merc dealer or speciallist should be able to reset them. I had the same problem when I bought a 1991 R129 a couple of weeks ago. It had been left standing over the Christmas and new year break and the TOAD had flattened the battery. It was taken to a merc specialist who reset the system. Batteries are definately sensitive to cold.

I gather there are sometimes problems with the wiring loom on the 93s and 94s chafing and causing wear that results in shorts, although I've not heard any stories about the loom being sensitive to cold.

Hope this helps.
