Had a bad L front wheel bearing. Bought a new one and replaced it...still have same noise and bad vibration plus ABS, traction control and parking brake lights come on. Also noticed a loss of power more so going up hill. Now what? Help!

 

take it to a audi mechanic and have a proper diag and inspection done on it

 

As far as the power loss, when's the last time you swapped plugs and coils?

 

Check your brake light switch for the abs, traction control and the parking brake light issue. Do a search for brake pedal/switch
