HELP! how do you replace the air filters???

Recommended Posts

does anyone know how to install the aftermarket air filters for a cayenne turbo?

I see the spring clips on the top but something is holding the rest of the housing on the bottom.

I found a DIY here at renntech, but it's for the Cayenne S. The piping on the turbo is different since the S' intake goes directly to the throttle body.

I can't seem to be able to get the housing lid to come up and off.

Loren, do you have a TSB for replacing stock filters?

There is a not a TSB for the air cleaner on a Cayenne TT and the owners manual is very vague. I personally haven't done more than look under the hood on a TT Cayennne so I can't help you here. In most of the Porsche air filter designs you have to remove an intake hose clamp or other connecting pieces to lift the top off.

Perhaps another Cayenne TT owner figured it out and will post here?

p.s. Once you figure it out take some pics and we will put it in the DIY section - credits to you of course.

So I gave the dealer a call.

fairly basic...

1. remove all pastic trim pieces around the engine bay via 1/4 turn screws (watch out the pop out sometimes), you'll notice the air filter housings on both sides.

2. start with the driver's side and look for the 2 plastic torx screws (T27) on the lids of the housing.

3. Look closely and you'll notice the head of the torx screw is not round. it was a small extension protruding form the circumference of it.

4. look even closer and you'll nitice a black dot debossed from the housing around the head of the torx screw.

5. line those 2 up and give it a pull and the whole pin will come up.

6. undo the 2 metal spring clips and you'll be able to pull the lid completely off.

7. replace the filter and repeat steps for the otherside.

8. However, there is 1 extra step on the passenger side that needs to be taken.

you'll notice a vacum tube in the rear bottom of the lid that needs to be removed first. It's a *****, but it does come out. don't forget to out it back in when you are done changing filters.

9. all done. :thumbup:
