Don't forget to clean all the leaves and debris from the radiators. Bumper off !

Oh right. For some reason I thought this filter is from your own car. Glad to hear it's not.

I described the whole story in another Thread. The short version is the owner put Bardahl No Smoke and some other snake oil in his oil to 'fix' a red 'Low Oil Pressure" Warning Light. I did an oil pressure test and dropped the filter and pan. Cut the filter & voila. Correct oil+new filter fixed it !

Here is a photo of the collapsed filter pleats on a Napa 1042

The LED bulb replacement is a great project. Somone should write up a Tutorial with all the part numbers and a good source for the new bulbs? Thanks for the suggestion.

I think it's actually important to use the maintainer for lengthy periods when you are not driving the car. These cars are battery hogs. Electricity is drawing all the time. Notice how the interior lights stay on and on and on. I often park my car for over a week at a time when on the road without a maintainer and that's always been ok. Of course I'll start the car and let it run about 5-10 min every now and then. If I'm away from home for a longer trip, not driving, I'll always put the maintainer on the car. Cheap insurance against a dead battery and messed up electronic system. And, as an aside, you can get a good maintainer on line, or from Sunset, or elsewhere. Check out the manufacturer. Mine has the name Porsche on it, so it costs about twice as much as the same one that doesn't say Porsche on it. Your choice.

Hi, I am Maarten from Amsterdam, NL. I drive a 2003 Cayenne turbo that has a faulty air suspension. I had the yellow "airsuspension faulty" message a couple of times over the last two years but now the car "lies on the floor" with a red airsuspension warning. Compressor is not running, when I connect the spare tire hose: no pressure either. When I bench-test the compressor directly it runs fine. At that point I decided I need a diagnostics computer and bought a Durametric kit. I get the following error messages from the Level Control module: 2250 (valve operating time exceeded, upper limit value exceeded) 1575 (manual control switched of) 778 (steering angle sensor, No signal/communication) [Cornering lights do not work either] 1487 (System function test faulty, Implausible signal) 1772 (Signal lead for pressure sensor, Implausible signal) When I try to read the actual values, I see things like compressor temperature and Compressor relay (off). I also read "System Status Number Control Mode" which reads 4010. "Deviation from normal level" and "absolute vehicle heights" also show plausible numbers. Battery is in good shape. When I scroll further down, there are many signals that do not show any values and that seems strange to me: "Accumulator pressure", "Terminal 15" all stay blank. Maybe these are simply not supported by Durametric? Any tips? Where is the pressure sensor located (related to 1772)? Can I start the compressor manually to fill the system? I know the Porsche tester can fill/bleed the Level Control System Thanks in advance, Maarten
