its a 2005 Audi a8 v8 and after i changed the abs control module the brakes became week and the abs light and the brake light were still kept on,

during the change some oil came out from the pump pressure valves,

could that mean that air got in side the brake lines and that i would need to flush the brake lines. pleases help.

 

If you didn't bleed the brakes after, I can assure you that you have air in the system.
