ABS Module Failure - question
 

Hi, I have a 2000 9-5 wagon 6 cyl).91,000 m. My check engine, and ABS, warning lites came on . Dealer says needs ABS module replacement: $ 3000 if new, $ 1300 if sent out to be repaired (one week).
Searched this here, no results, wondering if this is not too common?? Also, if modules can be found on Ebay etc and installed by experienced non-dealer mechanic?? If so, typical cost of module? Thanks a lot for the help.. Steve
