Cooling Fans
#6
hdi fans are controlled by the ecu there is no fan controller bitron unit like petrol and earlyer cars,
i sespect you have fan issues due to the fans themself not working or the relays or the temp sensor on the block or as nial says the multiplug on the fan assembly

turning on a working Ac system brings the fan on in slow speed both fans are connected in sieres if one is broken both wont work!
when the car gets to temp the fans run at high speed both are in parrellel if one is broke only one will run
