964 ABS/AWD WARNING LIGHTS

Electrical and Electronic

Vehicle Information: Year: 1989; Body Type: Coupe; Engine (type, size, modifications): 3.6 w/ K&N filter, headers, exhaust; Total Mileage: 36000;

I have one of the first C4 cars built out in the shop, and I think on of the first in the US (white, no airbags). The AWD/ABS light comes on after startup every time, and has been doing so for several years. After I hit the "!" button, it will sometimes come on again. I had the hydraulic system bled, and this did not make a difference. Several very reputable mechanics have told me that the computer needs to be reset - - is this something I can ignore or could there be a larger issue here? By the way, I do not detect any obvious leaks (my undertray was removed following the exhaust upgrade).By the way, I did read a previous question pertaining to this issue and you mentioned the servos.....Thanks
