Hello Trevor, I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.
I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.
I can continue to wait, cheers. Trevor
Hi Andrew, apologies for late reply, I haven't been available for a few days. I have since removed the grey relay again and the fans continued to run so fault is not straight forward & today fault has vanished, for how long I don't know, but I'm not feeling that reassured at present.
Hi Andrew, back to same fault today, removed grey relay one fan stopped removed 40amp fuse both fans went out came back on , with both disconnected could here electrical buzz from top right of engine disconnected sensor plugs but couldn't locate, I think a trip to the dealer is looming,
Trevor P S tried disconnecting battery for long period to reset parameters but no success
no I don't think so but I didn't have my stethoscope to pinpoint it I will check during week as mine is at work let you know
Ok sounds good.
Hi Andrew, buzzing coming from solenoid behind Bosch unit at back of cylinder head (transmission end). Could not remove plug as in awkward spot behind wiring loom under bulkhead. Relay controlled as cuts out after approx. two min's . Where is relay that operates solenoid as it cuts the fans out too? Tests were done with grey relay & 30a fan fuse 15 ( in front of grey relay) removed.
