Hi, my dad has a is200 2 litre v6 02 plate. Recently the abs pump has failed, I got him a 2nd hand one from a scrapyard which turned out to be faulty also. Does anyone know where you can get the abs pump refurbished? We have tried quite a few places no-one seems to be able to help. Lexus want £800 + vat for a new one! He really likes the car and wants to keep it, as the car runs great apart from this and is in good condition. Any help would be appreciated, thanks.
