The reason unpainted is because if they had to move to the inside they are different colour gloss black as outside ones are body colour. After a month of no issues the sensors were take out and sent to body shop for paint and then reinstalled and have never had false bbeping since. Previously to replacement I had 6 months of false beeping.
So, even though your 2 original front outside sensors "worked", they replaced them and gave your car back and the problem stopped? If so, your dealership is a keeper because they offered an alternative solution. My dealerships here won't go to those lengths and they keep saying they can only diagnose when the problem is occurring. Their latest suggestion is for me to take the tech on an extended test drive to trigger the problem. Now, I'll tell them to do start replacing sensors until the problem stops.
