I believe my Audi A6 2.8L 1998 Quattro has no ESP. I do have ABS.

I start up car, and I never see the ESP light like others said.
and when I drive on snow, I still skit.
Also, when my ABS activated. the dash doesn't have the ABS light on. is that normal?

My main question is:
So can I add ESP to my car?
like add the unit?

Thanks guys.

 

No you cant add it

The ABS light doesnt come on unless there is a fault
