Help .
after taking advise from dealer about storing for winter, blow tires to 45 psi....i decided to drive the 2004 A8L ,
i corrected the tire pressures to 35 all the way around, i got a sign ...tire prssures malfuction....i cannot correct this i tried to reset to factory settings...ran the car on the high way for 10min,.
still getting light.... the only way to make it go out is to switch off the "display tire pressure" option.
any suggestions.
