No Heat with Error codes in IHKA
2008 528i LCI
Out of nowhere, my car will no longer blow heat. No matter how high I set every temp even the little red and blue bars, it will only blow cold air. I use the Carly for BMW app so I was able to diagnose everything just still not sure! :( I isolated the parameters for the water pump and figured that it had the proper voltage, etc., leading me to believe that the problem is not the water pump. However, I did get fault codes in the following manner. My gut leads me to believe that it may be the rain/light/solar sensor (part# 61359201989) is acting up. The only thing that is throwing me for a loop is that the light and rain portion of the sensor still provides the correct information to the ECU to allow the headlights to still turn on and the wipers to wipe.:unsure: I read that the solar portion of the senor tell the IHKA when to blow heat or cold. Light/Rain Control: Rain/light sensor / Regen-Lichtsensor RLS ECU OK, no Fault Code Light / Licht Fault: sorry, unknown fault Code: A8C4 Heating / AC: Air conditioning / Klimaanlage Fault: Monitor sun sensor supply Code: 9C6D Fault: Monitor Fondpotiversorgung Code: 9C6E Fault: Error fogging sensor - K-LIN 3 RLS Code: 9C55 I have no idea if I'm heading in the right direction or not. Hopefully some peeps here can help!!!;) |
Well, fixed it. It was the light/rain/solar sensor. Heat blows fine again. Got the new piece off of eBay for $36 used.
