Got my manual fan switch (hi/off/lo) installed, as well as replacing toasted ballasts. I like the functionality overriding the system as needed.

My question though is that by system default the lo-speed fans should turn on at 97 deg C, suggested by the Bentley manual, but mine do not until 102 deg C. The temp reading is from the climate control hack so should be fairly accurate, as you would read from the proper diagnosis tool. Is 1997 DME programmed differently or any faults in the system to be looked at?

For now I can flip the switch when I want cooling but just wondering...
