Porsche 986 Radiator Cleaning | Must-Do DIY Maintenance!

Dreading having to remove to whole rear bumper assembly, I finally got to it & figured it out by unbolting the Rear Bumper/Muffler Heat Shield, then pulling the bottom lip backward to allow the bottom of the plastic bumper trim to be pulled down over it (holding it in place albeit lower providing more access room), remove closest 1 bolt of the lower left plastic valence piece to drop down & hook to the lowered trim piece, AND having a trailer hitch - unbolted the wiring harness plug assembly to move up & out of the way allowing enough room to reach into left inside plastic bumper/spoiler, find the inner left sensor & snap it back into place (no plastic tabs were broken). Easier than a complete bumper removal.

I’ll share with you the problems and solutions that I experienced with our 2009 Base Cayenne with the hope that it will help someone in the future. My 2009 Cayenne stalled. I attempted restart but there was no electrical activity at all. There was no instrument panel display, no power to anything. The key was locked in the ignition switch and the shifter lever was locked into park. In order to move the car, I found the "emergency" instructions for unlocking the shifter from Park, it involves removing the center console and using a screw driver to push the locking arm which frees the shifter to move out of the Park position. It is a good idea to locate the process, print it out and keep it in your Cayenne as tow truck drivers may not know how to do this. There are many online descriptions of the process. If the key is locked in the tumbler, there is a small dimple point on the lower left tumbler face. Use a small pointed object to push in on the dimple and turn the key to the off position and remove. I believe the battery shorted out as a jumper battery didn’t assist. It may have caused fuses to be blown. What I did and observed: 1. Replaced the battery, still no electrics, shift lever locked, key locked in the ignition tumbler. 2. Kessy Control Unit Fuse #41 15A (all 2003 – 2010 Cayenne) on the driver side fuse box was identified as blown. Replacing it with a good fuse turned on most of the electrics, was able to shift out of Park and remove key from the ignition tumbler. Still no engine crank. 3. Fuse #23 10A Porsche Stability Management, passenger airbag deactivation, brake pedal switch, instrument panel, engine control unit, airbag control unit, steering column module. Engine immediately started after this fuse was replaced. I recommend that all Cayenne owners carry a spare fuse kit with a fuse tester. Make sure you have the owners manual or a print-out of all the fuses. There are fuses on the left and right of the instrument panel and underhood. Knowing these failure modes and key fuses can quickly address problems that can immobilize the Cayenne. Following replacement of the fuses it runs perfectly.
