Just bought an 04 C70 with 74k. I've always been an Audi guy but my 96 Cabriolet finally succumbed. My mom traded her 64 on an 81 when she had to drive 8 miles to buy leaded gas. Also, at 63 she grew tired of shifting. I ultimately inherited her 81 240DL with 101k.

Yesterday, for the first time, my snowflake, anti-skid, abs and brake warning lights came on. I could not lower the top. Anyway, I stopped and restarted and the lights went away.

Same thing happened again today but while I was driving the lights reappeared. I've tried to research this but everything seems to lead to the yaw sensor. Never had one of these on a car before. At 70 I am too old to start pulling out seats.

Could my dog (40lbs) in the passenger seat have any effect on this? I am guessing the seat is weight sensitive. It has only occurred when she was riding shotgun.
