I am in need of replacing an ABS module for a 2004 VW Passat (1.8 lt, automatic). I picked up an ABS module for it, however it's not identical to the previous one. I know this car has the ESP feature, so I'm assuming the traction control makes a difference with the ABS module.

Is there anything else I should be aware of before I make a purchase? Any advice on this matter would really help.
