Hi,
Ive got exactly the same problem and looking to get the ABS replaced.

I've had my car to 3 garages. 2 of them say it is the main ECU and one says it's the ABS. Reading online confirms that it is definitely the ABS ECU. Rather than getting the original part and forking out 30% of my car value sounds ridiculous.

Can someone please help me in determining the exact parts that I need to get? i.e. is it the whole ABS pump and ecu that i need or is there something else as well? Modulator?! I am a newbie in this and appreciate experts help.
