    Would appreciate any help... TIA!
    2010 Corsa 1.2 SXI
    Amber Engine light on but no codes from ODB reader
    Radiator fan comes on as soon as start-up & noted slight under power episode other day but don't drive car regularly so don't know if this is persistent issue (running too rich?)
    Info obtained so far points to Coolant temp sensor - shouldnt be the one at bottom of radiator as changed that last year - OBD picked up appropriate code.
    Coolant temp sensor supposed to be top left engine block - not there... where? Other info on t'internet point to being on right side engine... but, went to local parts stockist to buy sensor - they could not find Temp sensor (other than Rad sensor) on their system - ? coolant temp sensor in Thermostat housing - is this correct? (not fitting yet as trying to check before doing same! £40!)
    Any help appreciated!
