I have a 2002 C3 1.4i petrol. It has covered 120,000 since we bought it new. It has just failed its MOT due to a seized abs pump (the dashboard warning light won't extinguish even after the ecu has been reset). So there are 3 options open to me. 1: Get Citroen to supply/fit and code a new pump. 2: Scrap the car. 3: Locate a secondhand unit and have my garage fit it. 1 is never going to happen as the cost is greater than the value of the car. 2, I would hope would not be the case as it would be a terrible waste. So that leaves 3. So the question is this. If the pump and ecu are specifically coded to my vehicles chassis (so say Citroen), I know its possible to obtain a secondhand unit off of Ebay lets say. Therefore can my garage separate that pump from its own ecu, do the same with mine and refit the replacement pump to my ecu and then reinstall it into the car, thus resolving the problem and avoiding a 1400 bill from Citroen or indeed scapping the car? It appears now that we are not throwing cars away because they rust to death anymore, but rather that their electronics fail them! Many thanks alanhatter
