I'm not going to pretend I understand but I'll be passing it onto someone I hope will aha. Thank you very much for your help buddy.

Cheers for that buddy. Now I just need to find out the flow rate of the resistor. Would anyone know if they're are separate resistor for each fan speed or does one work the two? Basically, I'm trying to find if I can get these parts from Maplins electronics and save a few coins - because I'm not sure if the resistors are the problem; so don't want to fork out BMW prices on something that works perfectly fine. :) Thanks in advance.

Hello, Could anyone tell me the function of a resistor and exactly how it works, please? Also, If anyone knows the voltage of the resistor pack in a 2004 r50 that would be awesome.

Thanks for the reply! The heater blows warm air fine and all the pipes heat up but will check the radiator.

Also, if anyone could let me know at what temperature the 1st stage and second stage fans are supposed to kick in, that would be greatly appreciated.

Hello I'm a new member so greetings and thank you in advance for any help. My son has a Mini Cooper 54 reg and recently had coolant issues; First of all the fan kept coming on loud so assume it went straight to speed 2 - Once or twice this continued once the engine was switched off. Then we found the water level to be low so topped up and ran it, fan still on constant as soon as engine started. Water leak on radiator was discovered so we added rad weld stuff for quick fix until fan issue sorted then new rad will be fitted. I have replaced the thermostat, checked all fuses and checked the temp sensor on passenger side of head next to the thermostat and swapped fan relays around inside and under bonnet. The sensor ranges on a volt meter are 8.44 when cold and drops to 1.95 when dropped in hot water so that's moving. With the sensor back in and engine running I unplugged the sensor but the fan continues to run and temp gauge shoots up to red - fan continues. Placed snap on code reader no faults logged checked engine temp was at 82 yesterday after engine ran for 10 mins and never overheated - placed it on this morning engine cold showing 21 engine temp fan kicked in as soon as started temp still on 21 Looked tirelessly on various forums at posts on fan resistor but haven't found anything that relates to this issue all seem to say fan continues to run once car switched off. Would be very grateful for any help and insight.
