My speedometer is not working and the ABS/TRAC lights are on. These three things are all connected; occassionally they all work, but only for about 10 minutes. The check engine light is also on. Audi replaced speed sensor as well another sensor they thought was causing the check engine light. Did not work. They also checked the connections; did not work. Now they are recommending replacing the ABS control module ($2100). Is this really the problem?
