MY REPAIR WAS FREE! 2006 BMW 330xi fan not coming on and caused overheating. Tried and tested everything in this video and still no fan. My solution: Multimeter test ground and power from thermo switch to fan plug. voltage to fan was good as was the ground. A third wire, REFERENCE WIRE, had no voltage, the reference wire has to put out around 4-5 V. My reference wire had rusted in the harness and caused a short(harness is located along the right side under the radiator shroud). After inspecting the harness, I came across a discolored spot and decided to slit the wire to see any damage, sure enough, the wire was hanging by a strand of wire. I spliced the wire, soldered the connection again and Voila! Fan is alive!!!!! Maybe you'll get lucky and this is your cause.

[@josephharding1984]

I have a 2007 BMW E90 built in August 2007. The sending unit is just below the oil filter on the head. It does not have a sending unit on the lower radiator hose. My fan is acting up. Sometimes it comes on with the air conditioner. Sometimes it doesn't. If I unplug it from the sending unit sometimes it'll come on on high. Sometimes it only comes on when I plug it back in and only runs for a minute or two and shuts back off. Can you tell me what's happening here? And is there a relay for this car for the fan?

[@mhdprestigevtc8994]

Is this the same sensor which tells the engine temperature on the cluster guage ?

[@carlitoselbuho]

so, question??? first we drain, then we refill and bleed it and then we remove the old sensor and install new one, or first remove old sensor, install new one and then drain refill and bleed???

problem of the radiator fan not comes on when AC is turned on BMW or comes on with low speed? could you help me to find the problem?

[@TheManThatCan1002]

I've got a 645ci that the fan runs for about 10 seconds at cold then sets off a engine malfunction on the entertainment screen and shuts the fan off. Vehicle will overheat and fan will not respond to activation in scan tool. It sets off a DME Fan Activation code in the scan tool. Any clues?

This is not an e90 335i. Every google and youtube search I do for 335i or N54 lands me on results of you guys working on anything BUT a 335i with an N54. I'm glad you're building up a following on youtube but that seems to drive search results to your videos, and you're doing it by spamming keywords in the description as is often done on craiglist.

[@pedrodelasancha1854]

Thanks a bunch for your videos. You guys are fantastic. I have a question regarding the cooling. Hope you'll see my comment. I have a 2007 BMW 328i sedan. The fan won't engange. I've tested the wires, coolant temp sensor, thermostat, water pump and fuses. Replaced Thermostat with OEM, Coolant Temp Sensor, and Bled the system. The Fan will not engage even when the temp rises all the way to 220 deg Farenheit (104 c). So, I thought maybe the fan is bad. Side note. My Beemer has a temp sensor at the radiator outlet hose but there's no connector to it. I've looked everywhere following the harness down to the inside of the cabin and no Connector. Anyway, I bought a new coolant temp sensor (the one mounted at the engine). And the way I tested the fan is as follows. When the engine is running, if I disconnect the Coolant temp sensor connector. The fan automatically kicks on. That's what's supposed to do, I'm told. But I wanted to make sure the fan is in good working condition by connecting the old temp sensor outside of the car (The new sensor installed in the car so the coolant wouldn't leak), then I started the engine. I applied heat to the old sensor with a heat gun and while measuring the resistance as the sensor started getting hot, the fan kicked on when the sensor got to around 208 degrees f (98 c). That proved the old sensor was working properly and once it's hot, it commands the fan to engage. Problem is, once the sensor is installed in the engine and temp gets real hot, the fan won't come on at all. Sorry for the long message, any help will be greatly appreciated. I'm at a lost here.

[@OmarGUSMC]

Did you ever figure this out?

[@pedrodelasancha516]

@@OmarGUSMC Sure did. After checking everything I mentioned and bleeding the system. Making sure there were no leaks. I decided to take it for a ride. I connected my Maxisys Scanner to see live data. 15 mins after driving the car. The temp went up to 228 deg F. Then all of the sudden, the Fan kicked on. I suppose the coolant needed to recirculate long enough to get the Temp Sensor to detect the right temperature. 👍

[@bathanmark]

@@pedrodelasancha516 hello, how's the car behaving? Does it mean the problem is the poor circulation of coolant and it doesn't reach the sensor in your engine?

[@griffenjacobsen8541]

Good video, but not enough help. I have a 2006 3Series with an N52 engine. I have replaced the Fan assembly, Aux fan switch, Thermostat, upper and lower hoses. I have verified constant voltage in red/black wire and good ground on black wire. Fan still doesn't run, ever. A/C on or off, at start-up or after running until it overheats. I was under the impression the relay was incorporated in the fan assembly. Need some in-depth help on additional relay and wiring harness. Help/suggestions please.

[@abrahamvera6366]

Having the same problem with my 325i cant get the fan to turn on and if it turns on it rotates slowly and then stops working again basically everything is brand new might just have to end up taking it to a shop and get taxed.

[@griffenjacobsen8541]

After searching this and other forums, found that the answer was to clear all error codes. Hacked the hidden menu to monitor actual temp while running and her behaves as expected now.
