Help needed, A/C menu specific to 2005 E55
I am having trouble viewing the a/c menu on my MY2005 (production date 07/04)... I have a REST button, but it won't access the menu, I even tried setting both sides to 72 and 75 degrees... I am trying to increase the radiator fan speed from adding a killer chiller... the pressures at idle are a high and a little extra fan speed should get it under control...

Jimmy, are you trying to change this permanently? If so I'd say just do it through star under correction programming for the ECU. That's the only way on my 06 that the settings stick. I think it will let you correct the temp by up to 12C IIRC.

we figured out how to do this via star... my main issue is this correction is for cooling, the ME doesn't make a correction for a/c pressures... i am currently working on putting a resistor in line with the high pressure switch to see if i can trick it into thinking the pressure is high, thus putting the fan on high speed...
