Tools I Use!

You don't need to replace it. Just take it out, open it up and clean it. There's a plastic gauze in it that gets caked with air particles that won't let air through. The sensor cost 100 US so fuck that i cleaned mine and it worked fine. Opening it is a dremel cut, then glue it back together. Takes an hour.

Just got a scan tool and this is one of the first codes i can afford to fix easily LOL. Might try that dremmel tool clean first

So clear in all his videos, delighted to watch, highly recommend

Mine has pretty much not been working for the more than 6 years I have had my E61. Btw. it's only potentially being used by the car when you have the air re-circulation in A- mode *automatic*. In this position the car will take air in from the outside until it senses the air is sufficiently polluted - then it switches automatically to re-circulation. So not a big deal unless you travel a lot in areas with a lot of pollution, there it will come in handy.

I study the EGR removal for my bmw N47 e87. There are so many opinions on this subject and so different ones. Some say the engine will get too hot by removing it and will result in long term wear. Some recomend removing (you also as I see). I am not convinced what to do..

2008 750i and fans stuck on high if motor is running and since that started it wont cold start ive replaced water temp sensor and water pump sensor no fix, now im putting in new thermostat with sensor and hope that does it, do u think im gonna fix it or is it something elese like module?or fuse?

[joshcatalano]

When do you know it needs replacing or will it show in the cluster?

[germancarfan]

Thanks I just had the fault code come up on my 330d

All this does is automate the Recirculating valve for the cabin air. thats it. you dont HAVE to change it. you can manually select recirc in the cab by the controls. replacing it is more to get rid of the constant error it gives.

Why that thing costs so much is anyone's guess.

Mine was broken without error code. Just lost its sensitivity.

In F30 3 series you can hear it very well if it switches into recirculation mode. One day i wondered why i didn´t hear the recirc noise for a long time, so i started to investigate and tested the sensor by letting my gasoline brushcutter blow some exhaust on it while reading the AUC sensor data with OBD. Showed almost no reaction.

After replacing the sensor i repeated the procedure, the new sensor reacted immediately and switched into recirc mode. The new sensor has a "02" version index on it, so i hope BMW optimized it to last longer than the original "01" indexed version.

would this sensor tell the computer diagnostic it has 0 pressure? I have changed the high low pressure valve 3 times, the gas is charged and with pressure but it doesnt detect the pressure so the compressor never turns on

[AshG]

Dude you got any vids on the exhaust back pressure sensor?

[natsiel]

Hi mate. I have a CEL on and codes I have are 801225, 801224 and E71439. What may be causing this, just had air con recharged but still have light on.

My BMW keeps alarming intermittently when parked. Is there a video that shows how to check all the sensors on the BMW?

[egabe]

Hey man to do know what the sensor on the same spot but opposite side is for ?

[smamas]

I have an error, 9c54-ihka auc sensor, is this the one you talking about right??

[PhatBoyiee]

What program are you using to check the codes?

[SiddharthaRoy-ir]

Does this sensor have anything to do with the oil sensor and engine tempeature guage going up? Have changed all parts on my F10 but still car gauge is going slightly high on long drives

[fraizer]

thank you but what this sensor supose to do when it detect toxic smells etc ? you dont explain this importatn part on your video. :)

[beemers]

If only all jobs on these was this easy
