This is exactly the same problem as mine which has also been discussed in this thread.
I just developed the exact same problem as the OP. Its different than most problems that I have searched.
No warning lights at start up or initial drive. Its when I drive ~15 min at freeway (60-80pmh) speeds that the PDAS light comes on and alarm comes on.
If i drive on the streets (30-50 mph) and go from stop light to stop light, the car does not have any issues.
It seems that the PDAS light comes on when the car is driven at freeway speeds and the speed must be consistent.
It makes me think its the speed sensor on the transmission - i have a 89 C4.
What do you guys think?
