Abs ESP and bas lights came on same time what could this be? on 2003 Mercedes-Benz S55 AMG

Car threw all 3 codes at the same time. Don't have a clue what it could be . I had just left dealer getting oil leak fixed. Car only has 46,000 on it. Is it going to break me to find problem?

Was it on BEFORE you dropped it at the dealer? If not , bring it back.
no it wasnt on.but with them just fixing oil leak why would it cause all those codes to come on? do u have any idea what would trigger all 3 codes?
They may have left something unplugged or damaged something during the other repairs. IF THE LIGHTS WEREN'T ON BEFORE THE REPAIR THEN THEY SHOULD NOT BE ON AFTER, AT LEAST NOT WITHOUT AN EXPLANATION.
