Please let me know if anyone has had this problem before. Once the car is warmed up, every time I go over a bump on the road, the yellow LED on the traction control lights up, if it stays on for more than a second the red warning lights comes on and stays on.
Any idea?

'89 C4 here.
Exactly what lights are you talking about?

Also this may seem random but check your brake fluid up front and see if your on max (check this while the car is on, or at least on accessory setting where the brake booster starts)

You mean the light by the diff lock in front of the gear stick?

If so, it's normal for this to come on when you go over a bump in the road and it's indicating that the traction control system is activating.

Had the same this morning... drove over a speed bump with a little ridge on the other side. Very slow, but still the LED lit up. I'm not too worried as it went out shortly after and didn't get any real warnings.
