1) Anyone install HID's on their Volvo and know how to bypass the bulb out warning? I had no problems for the first month and then the car recognized something wrong and puts on the bulb out warning even though the bulbs are working.

2) My tires haven't been rotated yet in about 20k miles. I have AWD and I'm looking to rotate them myself. Do they rotate from front to back or diagonally?

Thanks.

 

Front to back.
