What diagnostic tool did you use? Durametric, PIWIS, Or PIWIS 2?

Here is what the service manual shows... (click to enlarge)

All of the stuff I have seen just says to center it - at the back edge.

:welcome: Digital Sound Processing (DSP) lDigital sound processingl (DSP) enabling the digital processing of speech and music in the amplifier is another optional extra. The sound package forms the basis. Apart from further acoustic adaptation to the vehicle, this function also allows spatial acoustic simulation. As a result, pre- and postreflection can be mixed artificially to give, for example, a concert hall effect. Different acoustic spatial effects can be simulated with DSP. On request, acoustic adjustment can be selected to optimize this spatial impression for the driver's seat or passenger's seat. Furthermore, programmed acoustic patterns can be stored and called up again. The separate operator unit is housed in the center console at the front of the passenger compartment. Different acoustic adjustments can be selected using the various buttons provided. Other equalizer functions (selectable frequency band) with several amplification levels can be called up using the optional extra information and navigation system (PCM). The DSP facility is operated entirely from the screen controls. The CD player (CD radio or CD changer) is recommended for optimum DSP sound quality). Functions: DSP button When the OSP facility is switched on, the functions last activated are switched on again. DYN button Speed-dependent volume and acoustic control is switched on/off using this button. POS button The row of LEOs briefly light up when the POS button is pressed. The listener's position can be spatially adjusted to the driver, passenger, or the middle of the vehicle using the arrow buttons. The LEOs are lit according to the setting. HiFi-classic-pop buttons A permanently defined acoustic pattern is produced when these buttons are actuated. The function can be deactivated by selecting a different acoustic pattern. User button The user function is used to create individual acoustic patterns using the room and echo buttons. Spatial impression and echo effect can be changed from low (lefthand LEO) to high (all LEOs) using the arrow buttons. MI, M2, M3 memory buttons Permanently defined or individually created acoustic patterns can be stored and called using these buttons. The listener's position (POS button) and speed-dependent volume control (OYN button) functions can be stored in the memory together with the acoustic patterns. • Storing: Press the desired memory button for approx. 2 seconds. • Selecting: Press the desired memory button.

Please read the Lost Radio Code FAQ. "Can you give me a code for my PCM? These units are manufactured jointly by Siemens and Becker, and the only place where you can get the codes required is from the dealer/OPC. The PCM’s require two codes, the ICS/Siemens code and a Becker code. The ICS is the first code requested. Sorry, the only place you can get a PCM code is from a dealer/OPC."

News to me... the only big confusing issue that I know of is the bad engine ground (splice) that caused all sorts of erroneous faults. But there was a TSB with instructions of how to fix that. Any combination of faults for the sensors listed may indicate this ground splice is broken or faulty. Mass air flow implausible (P0068) Intake Manifold pressure sensor (P0069, P0106, P0107, P0108, P1183, P1184) Engine Coolant Temperature Sensor faults (P0116_P0119, P050C, P3081, P3082) Radiator exit Coolant Temperature Sensor faults (P2183_P2186) System too Lean or too Rich (Bank 1 & Bank 2) (P0171_P0175) Oil pressure sensor faults (P0521_P0524) Oil Level sensor faults (P250C, P250D) Oil Temperature sensor faults (P0195, P0197, P0198, P0298) Boost pressure sensor (P1189, P1190, P1637, P1638, P1639) Camshaft position sensor 1 & 2 (P0341_P0349) Crankshaft position sensor (P0335, P0336, P0370_P0373) Engine Compartment temperature sensor (P1154_P1158)

The correct offset for a 986 Boxster with those wheel sizes is: 8 x 18 offset 50 mm 10 x 18 offset 47 mm

Fault code 1738 Possible cause of fault - Implausible signal (incorrect airbag sensor installed) - Open circuit (based on wiring between airbag triggering unit and airbag sensor or the airbag sensor itself) - Electrical fault in electric circuit (based on wiring between airbag triggering unit and airbag sensor; probably a short circuit to B+ or a short circuit to ground) - Faulty (airbag sensor is faulty) - Airbag triggering unit faulty Note: The six installed sensors have an identical design of wiring harness contact plug. Only the mounting points are different. The airbag sensors under the driver's and passenger's seats have a thread for fastening, while all the other sensors only have a non-threaded bushing. There is therefore a risk of confusing the sensors on the rear wheel arches with the sensors on the lock mount. If these are confused accidentally, the 9588 Porsche System Tester ll will display this fault code along with the fault type 'implausible signal'. Given this, it is always important to ensure that the correct sensors are installed at the correct position. This is because they have different sensitivity settings.

Sometimes you can reach in behind the wheel well liner with a mechanics hook and grab it.

The number one cause of "strange electrical problems" in Cayenne is a bad battery. Check to see if your Cayenne has the optional second battery - both batteries should be both load tested (out of the car) and have their specific gravity (of each cell) tested. Once you have a know good battery situation - then re-run the diagnostics tests using a Porsche tool (PST2, PIWIS, or PIWIS 2) or Durametric software. Only these diagnostics will give you reliable diagnostic data on Porsche cars.

Try the emergency release cable (item 29 in the diagram below). You may have to remove the right front wheel and wheel well liner to get to it. (click to enlarge)

Yes, on the cabriolet you remove the visor mount screws - then the rest comes off the same.
