ONLY APPLIES TO CONDITION OCCURING AFTER WORKING ON BRAKES
My son's 1998 9-5 had similar issues after we had rebuilt the callipers and had a general refurbishment of the front hub. No amount of bleeding the brakes or checking components resolved the problem. We were resigned to taking it in for a diagnostic report but found that after driving a short distance the warning lights disappeared despite having previously run the car in drive with the front wheels raised which was when we noticed the lack of speedo.
My guess, and had been a bit of hope, is that the system needed to recalibrate after all the work we had done. Perhaps it hadn't liked the front wheels turning whilst the back remained stationary - whatever.
