I have for sale an ABS module off my 00 S4. Its the bosch 5.3 module. It is currently in unservicable function, as it needs to be repaired. I got a replacement for this one. You could purchase this as a place holder so you can send your original out to be repaired or send this one out to be repaired. Or if you know how, you can repair this one yourself. I'm only asking $20+ shipping.

The bosch part number is 0 273 004 284. I got my replacement off of a 99 A6 2.8l. I'm not exactly sure which all cars this fits, but my best guess is that if the bosch numbers are the same, it'll work.

If you have anymore questions or want a picture, PM me.

Thanks
