Got a rock hit just above the drivers side windshield wiper on my 2013 X5, so instead of paying my deductible decided to pay $40 to get it repaired. Guy did a pretty good job and he found another crack to the side of the wiper blade and "repaired" that one for free.


Now the fun part, after leaving the repair and nearly home (10+ miles away) check engine light appears and the ambient temp sensor on the cluster is reading 120*f. But it was only 65*f at the time. Scan the X5 and come back with 5 errors and all are about the ambient temp sensor, the windshield and HVAC.



Clear the error and it goes away for about 5 minutes and then returns to displaying 120*f and CE light on. Scan again and again, same 5 errors. Came to find out that the windshield heating grid/wires in the bottom portion of the windshield is directly connected to the ambient sensor system and affects the use of the heating, and the HVAC too. Why it throws a CE is beyond me but it does.


Needless to say the glass repair (since they drill the crack to stop it, went into one of the wires and basically destroyed it! So forget the repair, now it's time for a new windshield.


If you decide to repair your windshield NEVER have them repair anything in the "black" area at the bottom of the glass or your just throwing money away! Figured I would post this as a PSA since this oddity happened to me!
