ABS light

[ed5000]

Hi,

I have a 1993 520 Touring. I'm having a problem with the ABS light on my dash. If I start the car without waiting for all the warning lights to go out the ABS light always stays on. However, if I wait for the lights to go out the ABS light always always goes out as well. The brakes are working fine. Does anyone know what the problem is? Also, Does my car have Vanos ? It's production date is 10/92. How can I tell if is Vanos equipped?

Thanks
