Brake Abs Warning Light Problems of Audi Q7

After leaving work one day, my esp & abs light came on. Everything was fine when I drove into work in the morning. The car was parked all day and the warning lights came on before I left the parking lot. The esp light shut off the next morning however the abs light stays on constantly.

Car stalled while driving on highway and esp/abs light came on - was told by dealer will have to replace the entire abs control module for $2800! to diagnose this took 2 days for the dealer and even then they are not 100% sure the replacement will fix the abs issue. Have already paid 500+ in labor diagnosis!.
