ABS Warning light
After disconnecting the battery on my 156 (S1) to change the belts, I have noticed since, that when I start the car, especially in the mornings, I normally wait for all the lights on the dash to go out before starting the car, but the ABS warning light comes back on for about 5 secs and then goes back off again. Maybe its a battery problem, as during the day it doesn't occur. The battery is the original (2001), so maybe this might be an indication she is on her last legs??
