Re: BMW Temperature Sensor

Hi,
yes guys you all are right regarding this mater..
Can some one help me regarding this. At the moment, both my e36 and e39 temp sensors are not working. In both cars, the sensors came loose, in the case of the e36, it was lost. In the e39 it was dangling. Anyway, with the sensors missing, the temp reads -35 in the e36 and -40 in the e39. I have purchased replacement sensors and looms for both cars, but with the new sensors installed, the temp still reads -35 & -40 respectively. Is there some kind of reset needed for the OBC to read the replacement sensors?? Another quirk, the e36 AC is unaffected by the ambient reading of -35 while my e39 AC quit working when the sensor came loose. Could the -40 reading disable my AC, or is this just an unfortunate coincidence? Any wisdom would be greatly appreciated. For such a simple repair, I seem to be getting nowhere! Thanks.
