My electronic parking brake has been playing up, first not releasing till after a few minutes with lots of button pressing and lots of warning lights on the dash.

It has also not been showing as being on on the switch.

Diagnostics have show an error with the module J540, can't remember the code.

The part number on mine is 4F0 907 801 (4F0907801).

Can I just replace this with one off ebay? Will it need programming to work with my car? Would it be better to get a newer one?

Are they any know faults with the module that an engineer like me could fix? (Not looked inside the module yet)

My car is a early 2006 4.2 Avant Auto.
