Good afternoon. I own a 2012 volvo xc60 T5. First of all, i had a oil leak from the transmission, so i sent my car to maintenance and they replaced some gaskets and the oil leak stopped. After i got the car back, i noticed that the sunroof and the Parking sensors systems weren't working. I found out that my battery died while the car was in maintenance, and i assume that they probably did a jumpstart. Anyway, after trying some online tutorials, i got the sunroof working perfectly fine, but my Parking assist system still not working. Every time i turn my car on, an error saying "Parking assist maintenance required" appears on the screen. Anyway, i called my dealership and they told me to bring the car at 28th december, but i need to use the car now. Anyone have any idea about what is going on in my car?
