CABIN FILTER REPLACEMENT/Hood Pressure Sensor

I can't seem to remove the the Hood Pressure Sensor on my 2007 530i. I want to change the cabin air filters, but I can't get the Hood Pressure Sensors removed. I turned it every which way buy loose, but they don't won't come out. What's the trick anyone? Thanks in advance.

Not sure what you are talking about when you say "hood pressure sensor", but if you are talking about the rotary clips, they only require like a 1/4 turn to release. If you are spinning them they are just locking and unlocking.

On the '07 530i, there are two Hood Pressure Sensors on the passenger side that MUST be removed in order to unlock the cabin filter housing. These Hood pressure Sensors are attached to the cabin filter housing on the passenger side. In other 5 series, these Hood pressure Sensors are not there there, but on the '07 530s, they are there.

It's the hood alarm sensor and it is in all E60's.
It's really easy to take it apart.
Youtube is just best friend.

To save you some time skip to the first minute.

Thanks UltimateDriving for the video, but I've watched that video many times, and still can't get my sensors loose. The video just tells you how that you have to detach the sensors but tit doesn tell you specifically how. I tried everything, but they won't come out, and I don't want to pull on it hard and break it. I thought it would be simple and straightforward after watching that video, but it's not. I need to know how to actually get the sensor out, because I'm pressing the clamps and everything but they're not coming out. Thanks for your reply.

You don't remove the sensor .... You just unplug the wire harness. You are pulling on the wrong spot.

I'm trying to unplug the wire harness, but it's just not unplugging. Do I need to pinch/turn a particular area ? Because I've trying for days now with this simple issue. Thanks for the reply.

There is no turning at all. The plug has a retainer like all the electrical plugs. Pinch the clips and pull the plug off.

I'll try it again in an hour...thank you...

There is no need to unplug that sensor.
- Turn 13mm plastic nut quarter turn,
- flip long metal clip that's holding the filter cover,
- pull out the filter holder little bit and flip it upside down,
you will be able to remove and replace the filter.

On my way to try that...all the replies are appreciated!!!

Worked for me like that as well.

Thank you everybody. I managed to changed the cabin filters with the hood sensor pressures still on; I just flipped the cover over and changed it and everything went fine just like Legend700 said. THANK YOU!!!

Glad it worked for you.
pcy described how to, I just agreed with his workaround.

Looking to do the same thing. I thought I would go to the dealer but this looks fairly simple to do.

1. Where is the best place to buy the filters? Should I just get them from the dealer or are there cheaper after market filters that I can buy that work just as good? (Do the filters have to be replaced as often even if I don't put many miles on the car?)

2. How do you reset the service alert?

Thanks!

As for resetting, please search, procedure is listed in multiple threads.
Essentially, you PRESS and HOLD the odometer trip counter reset button until you see the appropriate icon, RELEASE, then PRESS and HOLD again. You will see a prompt that'll say something to the effect of are you sure you want to reset. Press once and you are done.
