Citroen Saxo Engine Light Problem?

The engine warning light came on on my 2000 1.1 Saxo, just after I changed the original catalyst (rusted through) for a Bosal aftermarket cat. However it passed the MOT with the light on and drives fine.

Its now with a garage. They diagnosed a faulty sensor just after the cat and changed it. Problem still remains with the new sensor and the computer still says its the (now replaced) sensor.

Since the replacement cat was new, I assume it is fine but maybe it's actually the problem? A Citroen cat is £300 and I'd rather not go that route.

Any ideas please on what to do? Its costing a fortune and driving me nuts!

put some cataclan in the fuel run it all through the cat it will clean up the cat therefore not detecting anything- a catalit converter gets gunged up annd cataclean does the job just mix it with your fuel also find the sensor and spray with wd40 water displacment that took 40 attempts to get the mixture right :) the light comes on for a reaon either a false reading or could be a slightly blocked fault if resetting ecu and stil comes on

My saxo 1.1 51 plate, well, I was told the ecu,cat,sensors,and just about everything a garage can come up with, so sick of it I thought I'll buy a tin of w.d 40 and spray all the connector for dampest so simple, to complicated for the garage computer and guess what it worked

on some cars when a sensor or other component has been changed, the engine management light wont go out unless it is reset using a diagnostic tool even though the problem has been fixed. any garage with diagnostic equipment should be able to clear the trouble codes and reset the ecu. if the light stays on the scanner should then be able to detect another problem
