I have had the abs light on for the last couple of days

I just read how to test the sensors and have done it now, the front right has a very high reading so i guess thats duff

? any way i looked on ebay for replacement sensors and have found this listing
http://www.ebay.co.uk/itm/Citroen-Xanti ... 4cff0b95d8" onclick="window.open(this.href);return false;
but i am unsure if it will be correct for my car ?
can any one tell me please
