Could some one with advanced AC please take a pic of the AUC (auto recycle) sensor for me?, this is next on my check list for fitment and I need to confirm which one it is as there's two listed on the ETK.
it`s location is on the top left corner hand on the engine cooler fan cowling. Thank you.

 

I have a 2004/1 E60 with the automatic climate control.

There are two AUC sensors:

Heater and Air Conditioning => Control units, sensors, actuators

Item 1 64116933052 is located at the top corner of the engine cooling fan (right-side of vehicle).


Item 2 64116988303 is located at the cabin micro filter cover.

"What sensor is this?"

 

Thanks for that VK, you got me thinking now because the WDS only shows the AUC sensor fitted to the fan cowl. I wonder where the second one is wired to
According to the TIS there's only one AUC sensor as well.

 

You are correct. There is one AUC sensor per vehicle. I got confused with my E90.

On my 2004 E60, the larger rectangular style AUC sensor is at the top right-hand corner of the engine fan housing.


On my 2007 E90, the smaller round style AUC sensor is at the bottom right-hand corner of the micro-filter cover.


Both USA vehicles have IHKA High systems.

I looked at the ETK for the E60N (LCI). The round-style AUC sensor is listed, so they may have relocated it to the micro-filter cover area for the newer E60N.

 

Hmmm so I got a choice then the larger AUC is £66 and the smaller one is £30, its just so happens I have both fitting locations as well.

 

Parts ordered gonna put in the smaller AUC as that's the LCI one also ordered a ventilation sensor as well. Thanks VK.

 

well did you get the sensors ? where does the ventilation sensor fit ? gonna have to order these parts as well ,gonna end up an expensive heater panel this one do you have a part no for the ventilation sensor ?

 

forgot to ask and i have searched already 3am still searching ,where did you find the part no for all the plugs needed for the solar sensor etc ,as on real oem they arent shown

From the DIY ask at your local dealer.

 

forgive my stupidness lately im running on 4 hours of sleep a day .

ive already fitted the solar sensor

its the part numbers for the lci auc sensor + plug + contacts

and part numbers for the condensation sensors plug and contacts


really beggining to notice lack of sleep causes confusion.


i cant get time to travel to the dealers ,then have to return again a few days later to collect parts . my brother orders them trade and they get delivered to the garage but without part numbers its a hard battle with the bmw parts desk
