hi all i have a 2001 e430 i recently had front end damage and b4 i took the car into shop outside temp sensor worked now it always reads 31f i know its wrong today was 80f so i tried to put on a/c and i noticed didnt get cool as i was reading the factory hand book it says that the temp. sensor is located in the front bumper so i was wondering would my auto climate control not be working because sensor is not correct i have to take back to shop b/c workers put in wrong headlight not HID but the cheaper one so now i have one blue light and one regular looks to be a chirstmas tree light LOL and i wouldn't want to suggest this is the reason my air and sensor is not working without having proof or the facts. also i really regret going to this guy b/c everything is half done and when i mention things to him he acts as if im trying to get over on him when i know he's trying to get over on me b/c every time i ask him to show me service receipts he all of a sudden gets busy.
also i have been noticing temp gauge moving up a little not alot
