Thanks for the video---I just ordered the filter for $30. My dealer was charging $127.00 with labor. Once replaced, how do I reset the service in the odometer area to show this was changed?

[BentleyPublishers]

@CHOICEhiphop There is a procedure at the Bentley Publishers technical wiki on how to reset the indicator.

I have the 2007 335i, is there any difference or can I just follow the same steps?

[BentleyPublishers]

@Investman11 Same procedure.

[firechicken99]

what is phase 2 anyways?

[BentleyPublishers]

@firechicken99 Phase 2 is removing the lower housing.

@LOLitsJono Lysol may damage some plastic or rubber parts if used in excess. I would use it only lightly

@TheSRalston No, my Canadian Version has it. Most likely it was removed by someone or your E90 was in a accident and the hood was replaced. You can order the part from the dealer. Also, could be your model does not have one (different market).

@CHOICEhiphop DimsumE90 has a video online hot to reset your service indicator.

1) Put key in car

2) without pressing the brake, press the start button

3) Press and hold the trip computer button (cars w/o idrive only) until u see the yellow triangle

4) Use the trip reset button to select the service u want the change

5) Use the BC button and toggle stick to change the values

@BentleyPublishers

Does that have anything to do with replacing the microfilter? Also, how often should it be changed?

[TheSRalston]

One question. Do all E90´s lack the liner that goes on the bottom of the hood? I upgraded to an E90 and when I opened the hood I noticed it lacked the insulation cover I see on this car, they told me that "it had been removed from the model in a cost cutting measure". Is it so? Is this cover I see on this car an aftermarket piece? Thank you!

I think this is really use full so I know what I am doing. Better to just replace than to just clean u save money doing it Ur self

However, what is the right intake duct for? there were different components that looked electrical in nature and I did not spray Lysol for fear of damaging electrical components.

[LOLitsJono]

While removing this to spray Lysol Anti-bacterial spray to get rid of a musty/salty smell when I turn on the AC, I noticed that after you remove the Microfilter cover, there's two ducts as shown in this video.

In the left duct, I saw another circular type filter, similar to an air intake filter which I assume is part of the air conditioner and I sprayed Lysol in there. It seems to have worked but I had to keep spraying while the car was off, and then turn the car on /w AC on MAX. :D

[LOLitsJono]

Is this where the air intake is for the air conditioner?
