How to replace radiator fan relay on BMW Auxility fan relay switch N54 N52 Overheating 2efe code

[@alejandromartinez-ds1or]

I have 2008 bmw 328i e92 Coupé with n52 motor my radiator fan only twitches in idle but runs okay with a/c on not sure what the issues is I changed thermostat,coolant flush ,new resivoir , new radiator not sure what it could be or if I just need a new fan I think it’s the original fan too also got a new fuse to 😅

[@Makhnovets]

the 328 should have the fan switch, but if you don't it most likely the fan, just read the forum, the few people was going over the similar problem, the fix was the fan replacement. good luck!

Great, your video will be very useful to me. I have code 2EFE and the fan turns on but it blows when I turn on the air conditioning and it has to turn on at high volume.

Hello great video I have a 08 bmw 135i and I have the 2efe code I got a new fan from wrecker and still not turning on and I still have the 2efe code?

[@Makhnovets]

First is to make sure that you have this relay and if so, make sure it's working. www.realoem.com/bmw/enUS/showparts?id=UC72-EUR---E82-BMW-135i&diagId=61_3955 The problem also can be in the faulty switch. it's usually seats on the lower radiator housing, pass. side. but not sure if your car have it. make sure all related fuses is good. can you initiate fan from the computer"OBD II scanner"? you should be able to run it true computer.

[@guerrerola1237]

Thank you so much for your help and yes my car has that relay it’s cracked on the top will that be the issue, I also tested the fan fuse and it has voltage but when I tested the connecter I connect to the fan and there is no voltage.

[@Makhnovets]

Can you activate the fan from the software? Like obd scanner?

I have a 2009 E70 3.0. My fan runs on high when I start the car even when cold so I know it's not overheating. The fan runs for about 4 minutes while driving then shuts off. Then it comes on about 20 seconds later then runs for about 20 seconds and this cycle continues while I keep driving. Thoughts?

[@Makhnovets]

possible cause could be a failing water pump or thermostat, make sure to check the codes and see what you can find, the relay is just a pass trough, so it either work or not, temp. sensor could also be the case. good luck.

[@markoaleksievv]

Hello, great video! I have problem with my e71 X6 5.0i 2008 it shows the engine overheating yellow light then turns into red and I changed the antifreeze hoses because it was leaking and now it’s good from that point but the cooling fan wasn’t working too so I ordered new fan and replaced it and again the engine is reaching about 100 degrees and increasing up to 120 and overheating but the fan isn’t starting or when it starts it’s not working on high speed it’s not working properly, what can cause this problem? Sometimes it just starts and stops and repeats this action, what should I look for?

[@Makhnovets]

I could think about a couple of things. The first one is the temperature sensor, which seats on the oil filter housing, Second, it's the same location, which is the oil temperature seems. they are directly related to the fan speed. as for the coolant temp. it's normal for BMW to run hoot, as 100-110C, but the fan should be on at this temp. Good luck, and let me know if you resolve the issue.

[@persanu4923]

Is it in the same place on an x5 e70 3.0sd? I have a problem with the fan, it doesn't start all the time and only on the high mode. thanks!

[@Makhnovets]

It's should be there, also it's really easy to see it from under the hood, just see where the positive/Red cable from fan going, and it will get you to relay!

[@TUMEN08.01]

I cant find on my 2007 bmw 335i n54 e93. Is it in the same spot?

[@Makhnovets]

The simple answer is, you don't have one, the n54 have switch. you might have a relay in different location. you can check the "realoem . com", type your VIN and will give you all options and technicall spec of your car, then you can navigate to electronics and look for fan relay or cooling.

[@oso2916]

Did you have voltage on the connector to the fan? I have ground and voltage and continuity in my signal wire and I even replaced the fan but it’s still not activating

[@Makhnovets]

There could be the passage of voltage, but relay it self failing, and it's dirt cheap, so i would replace it anyway, there nothing else in between of the fan and DME, only relay! There little connect that comming from DME, if you replace relay and it still not working, there could be a problem in the wiring or connector itself, but like i said, replace the relay first, then go from there!

Yes, you should have one. and it's easy to check. Also if you gonna be ordering one, make sure you have the right Amp count, as far as I know, their variation of 150 & 130Amp. and make sure to disconnect the battery if you gonna be replacing one since it has a positive cable going directly in. www.realoem.com/bmw/enUS/showparts?id=KU63-USA-05-2016-F16-BMW-X6_50iX&diagId=61_3511

[@mozacs3482]

Hey did you find the a solution to your fan ??

[@Makhnovets]

Test it with A/C off. Another point if the thermostat stuck open or water pump reduced the speed the fan will work in full. Make sure you check if temperature stay at 95c’. Check the obd for water pump speed, or make sure you don’t have the messages that water pump is missing or reduce power.

[@darkxd8366]

So I changed my cars coolant temp sensor but sometimes when I start the car the radiator fan goes full blast sometimes. Do you believe is the relay

[@Makhnovets]

In theory, the relay has only one function, which is power passage. so if it's working-it's working. Make sure your AUC sensor has no messages, and also, the ambient temp sensor shows the right temperature. Do you have any messages on old? Just as context, my BMW X5 e70 was doing the same, because the AUC sensor was disconnected and wasn't working, try to clear the memory, make sure the AC is off when you start the car, and see if you have this problem, repeat with AC on. The fan speed is related to AC as well, that's why sometimes you got to make sure that you don't have a problem there. Good luck!

Hi! First of all the only way to spin the fan without harming anything that true dealer obd tool, as inpa or any other that have ability to trigger the component.

Trying to diagnose this issue on your own is alot of trial and error. Standard OBDII readers cant read the codes. I also used a SNAP-ON reader and all it said was “cooling issue”. Only the dealer can tell you the real problem. The diagnosis from the dealer cost more than the actual part…

First, the e90's don't have relay, in rare occasions they do but that will apply only to european cars. the 2eff is thermostate, or one of two element's that is made of, so I would assume you need replace thermostate and water pump while you there. the 2f71 on x5 for example is the fan that directly cool ECU box: www.realoem.com/bmw/enUS/showparts?id=FG41-EUR---E71-BMW-X6+35iX&diagId=12_1396

it could be the fan itself, the electric motor build from two stages, first for starting and second for running on speed, after starting the car try to spin the fan little bit, but be careful!!!! if it's still not starting it could be the relay, but most likely it's fan itself, any way it's cheaper to get a relay replaced first, then fan, like i said in previous comment, there nothing else in between the fan and DME except the relay. really small percentage can be the temperature sensor, but it's usually have problem with running on hi or low speed if it's sensor. good luck!

My dad 2008 BMW x3 3.0 just had a new thermostat put in and it didn’t help and it overheated the second time after my dad got it back what do you guys think it would be?

[@Makhnovets]

What code you get? also, do the front fan spin when the car is staring or running?

[@ChadWideman-ri6kd]

No the radiator fan does not spin when we start it up and let it run

[@bruskii_3364]

I have code p0480 on my 2009 bmw 335i pop up on my scanner its causing my car to overheat like 3-4 times but i know its not a blown head gasket even tho i had 2 shops tell me it was so im trying to hunt down the issue on my own is it in the same place and is mine a switch or module?

[@Makhnovets]

You have a switch. There tester for head gasket like this one, amzn.to/3Ee0J9y Get one it’s 99% accurate, in that case, you will know for sure. Before getting into any repair or replacement. N54 very rarely has head gasket problems. But the code is for a cooling fan, make sure the water pump and thermostat working correctly, the main symptom is the fan kicking on full speed, or it might was doing it before, in that case, you toast the fan. check the water pump speed, also try to actuate the cooling fan, there 4speeds for the fan, you can trigger it true INPA or OBD that supports the components trigger. See the readings off the temperature sensor and the consistency of the temperature rising. There are 3 things you need to check, cooling fan waterpump&thermostat and temperature sensor or switch. Good luck!

[@niewissen9912]

What exactly was your code? Auxiliary fan activation: line disconnected?

[@Makhnovets]

The code is "2efe electric fan, activation" That's mean either far or relay not working.

Good video. Music too laud though.

MIGHT BE EASIER IF BMW JUST PUT THE RELAY INSIDE THE OIL SUMP !!!

[@Makhnovets]

It’s not the worst engineering decision, but it’s not the best either 🤣 German engineering lol😂

[@tuhanpham]

Expensive car but parts break premature. Over rated car.

[@Makhnovets]

That could be long conversation, I’ll try to keep my thoughts short, what i want to say that the car is not overrated whatsoever, from my perspective it’s underrated, for the reason of maintaining, if you check the BMW maintenance shit, it’s say when and what you will need to replace at curtain mileage, and if you not ready to do that don’t buy the car on the first place, buy toyota which is cheap inside and outside, and doesn’t have advanced technologies inside, same as riding experience, quality of ride, and more, I know it’s not perfect, rither tessla or Ferrari, there also have they good and bad aspects. Non of the toyota will cach the eye same as BMW or Mercedese! The N52 and N54 engine’s are very reliable, in terms if you do proper maintenance!

[@tuhanpham]

I own bmw, Mercedes, Toyota and Tesla. Bmw break down prematurely. That’s all I’m saying, breaking down before recommending to change parts.

[@jessepullen6109]

Bro I fucking took my wheel off and the wheel liner and my shit was not there. This is not true for e60 I'm pissed I wasted my time and still can't find the damn location

[@alanwalters7411]

Why would you just assume that an E60 would be the same as an X5? They're completely different models so the locations of things like relays could also be completely different.

[@Makhnovets]

The “realoem” have diagrams, in Electronics section you should be able to find what you need. E70 and E60 has completely different components structure plus the year is a big factor.

[@jessepullen6109]

@@Makhnovets no doubt they are different. But in the video he says e60 is in the same spot ...

[@Makhnovets]

@jessepullen6109 I’ll double check with that, the chassis in X5 is very similar-same as 5series, but electrically would be different. My apologies if that was my mistake. Will make sure to update the information on that if so!

[@AndreGTunechI]

Is this location relative to the n55 535i?

[@Makhnovets]

Go on “realoem com” and check the diagram. Since I’m not sure if it has the same relay. As far as I know it doesn’t.

[@AndreGTunechI]

Thank you

[@sugardaddy3145]

I don’t have any codes but the fan is stuck on high and overheating, do you think this part would do the trick? It used to get stuck on high for a few min then disappeared but this week it hasn’t gone away ever since.

[@Makhnovets]

The Temperature sensor and Relay, Replace both of them. I would say the temp sensor multi-functioning, the one that seats on the oil Filter housing, it's cheap and easy to replace, you only need a 22-mm or 24-mm socket(kzbin.info/www/bejne/Z3K1pIKZmbWBfa8). The relay is cheap, so I would replace it as well.

[@otarsulava]

Question: 2015 X1 xdrive28i has the same issue, no fan is working. The relay should be at same location? Do I need OBD memory save plug BEFORE I disconnect the battery? Any suggestion? Thank you!

[@Makhnovets]

The relay gonna be a little different, and it's in the DME box. see the pic. here www.realoem.com/bmw/enUS/showparts?id=VL13-USA-02-2015-E84-BMW-X1_28iX&diagId=61_3822 It does not necessarily need to disconnect the battery to replace the Relay, but it's up to you. I never had an issue with replacing the fuse or relay on hot. just make sure the car is asleep (you basically have the key off the ignition and the car door is closed for at least 30sec).(or when the welcome light or any LED in the car is not lightning.)

[@otarsulava]

@@Makhnovets Much appreciate your response, Thank you 👍

[@林水旺-s6k]

So I have a quick question I have a 2010/05 BMW X5 30DX. Is the relay in the same place as your BMW because my fan isn’t working

[@Makhnovets]

Send me last 7 of the vin.

[@林水旺-s6k]

L427548

[@Makhnovets]

you don't have the same location or the same relay, the one you looking for is in the passenger compartment fuse box, Number:45, 60A relay. Also check the luggage compartment Number: 127, 5A

[@林水旺-s6k]

@@Makhnovets thanks

[@Thatbluee9x]

does anyone know the relay location for an 07 328xi? i cant find it anywhere

[@Makhnovets]

Read the previous review, it's like on 5 series, its a switch, not a relay for 3 and 5 series.

[@mikey358976]

Does anyone know the location on the radiator fan relay switch on a 2007 335i bmw twin turbo?

[@Makhnovets]

Relay is behind the battery in the trunk. Toward the front, there also some module sitting there...

[@mikey358976]

@@Makhnovets Couldn't find a video on it, except the one you have. hopefully you can do a video in the future on it. On locating the fan relay on a bmw 335i in the trunk. But thanks for the info.

Thank you for idea!
