Hello everyone! I’ve run into some electrical problems on my '08 Turbo and I’m stumped.... I've looked through a lot of Renntech posts and don't see any thing close.
First the panoramic roof and sunshade were opening and stopped about foot open. Maybe coincidence, it happened right when someone opened the door. I’ve checked practically every fuse even pulling the pano-roof control unit (back where the motors are located, and the circuit board looks okay. Then the instrument panel has started to act strange. The gear indicator shows that it is all gears at once, see the photo which is while it is in drive and moving. I can shut the car down and restart and the problem goes away. The time keeps changing randomly and the outside temperature is wrong. The button that opens the rear hatch that’s on the driver door has stopped working. Then my battery died, it was five years old so no surprise. After I replaced it the airbag indicator on the panel has lit up. I’ve tried to reset the instrument panel (Main Menu> Settings > Factory Reset) but it will not allow me to select “Reset”. I’ve also pulled the fuse several times to reset the panel but no change.
Today, I’ve connected my iCarSoft POR II diagnostic tool to the car.
The Airbag section says it “cannot connect to the ECU” so I can not reset the airbag light. There are YouTube videos of people using the tool on Cayenne’s (albeit on newer models) to reset it so I believe I can. The Panoramic roof says it does not have any DTC codes. The lift gate button on the driver door indicates it has appropriate voltage and no DTC codes. Also, no DTC codes for instrument panel, electrical system or DME I’m not sure this is related or not, I changed out the interior incandescent bulbs with LEDs. I now know that LED bulbs give off electromagnetic interference but seems remote. (as a side note, I found this out when I put LED bulbs on my garage door opener unit and it stopped receiving commands from the remotes – I had to get special bulbs from Amazon) Yesterday, I removed all the LEDs and went back to the old bulbs – no change.
Any ideas, suggestions or guesses?
FYI: The car is in Drive, "D" and is in motion.
Which radios fitted to Porsche can have their unlock code recovered through serial number?
- CR-220/CDR-220 - Becker
- CR-210/CDR-210 - Becker
- Traffic Pro NAV/CD - Becker
Which radios can not have their unlock code recovered through serial number?
- CR1 - Alpine
- CDR-23/24 (or later) - Becker
- PCM (Porsche Communication Management) – Siemens & Becker
How to get your radio serial number?
Hold down the TP button for at least 10 seconds after you turn the radio on. "Becker 1" will be displayed. Rotate the right knob (slowly) and it will display the Becker model number. Then rotate it again and the serial number should be displayed on the radio.
Or, if the radio is out of the car the then the serial number is on the label.
Press tone, then 8 and 0 simultaneously. "Becker" appears. Press station up arrow on right. "PR-VERS" appears. Press one of the numbered buttons below the display, directly below the LCD arrowheads (try a few). The model number will appear. Press station up arrow on right. "SERIAL N" will appear. Press the numbered button again. The serial number will appear.
Or, if the radio is out of the car the then the serial number is on the label.
CDR-23 (or later):
These radios do not have a security code - that is, not that the user enters.
These radios are security tested on the MOST (fiber optic bus) system to see if they are the "programmed" radio. The radios are programmed and recognized by the car’s DME and can only be replaced by a shop with a PST2 or PIWIS. These radios will not request a code when battery power is disconnected.
Select the Service Menu, press NAV and multifunction key 10 simultaneously in radio mode. Use multifunction keys Nxt and Prv or turn the right control knob to select the individual items.
You can move through the following items:
- Serial-No. <-- this is what we need
- Changer Reset
- Radio Software
- Radio Bolo
- Navi Rom
- Navi Flash
- RTC Value
To quit the service menu, press END.
I get a WAIT on the display - what do I do?
You have to wait at least 30 minutes before trying again.
The suggested number did not work - what do I do now?
Most often when the code we give you does not work it is because the serial number came from an old card in the car rather than from the procedure stated above - or a typo in the serial number submitted. Double check the serial number you submitted using the procedure above again.
If that does not work then you will need to contact a dealer or Becker. Becker charges to look up your code and some dealers also charge.
Our program works maybe 99.9% of the time but we have no explanation why it doesn't always work.
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.
Can I post my VIN to get a code?
We do NOT need your VIN - only your radio serial number.
Where can I post my lost code request?
Please post your request here:
Lost Radio Code - post your request here
Please DO NOT PM me or email me (or anyone else helping with the codes) your radio code request - we will only answer requests in that one thread.
So only managed to see a black square of tape expertly placed over the Airbag light (ON all the time), only because of driving it in the sun with the top down. Been concentrating on other parts of the car.
Any-who, that has lead to seeing that the Seatbelt light doesn't appear at all, and closely related, the horn didn't have a fuse in it at all.
So this has brought up a question, the Codes reported, the electrical drawings (Bentley), ....while they say "passenger" or "driver" side, does this in fact relate to the left and right side of the car when it is the probably more common "left-hand drive"?
Code 30 Ignition Circuit, side airbag passenger................is that actually the right side?
This will not reset with the Durametric. I looked at the airbag connector in the left door, but now I am thinking it may actually relate to the other side of the car, i.e. LHD passenger
Interestingly, the Airbag module wiring, Passenger Side Belt Lock, that wire is cut at the plug and a grafted in wire (plug connected) heads off under the dash somewhere (yet to be traced).
So that Br/Bl wire say passenger, but maybe it relates to the right hand side of the car, in this case the drivers seat.
BTW, the left seat, (passenger), does not have a wire at the buckle, but I think maybe the RHD ROW, or Australian RHD cars didn't have that anyway. Or has been replaced with the wrong buckle.
So maybe the Airbag light was covered to avoid looking for a fault, might be a plug.
Could it be related to the seat-belt buckle, again patched to avoid fixing it properly? The light doesn't even go with the self-test, so could be a bulb.
I have read that the seat belt buckle may not be included in the Airbag ignition circuit for this region.
Horn didn't have a fuse in it. Relay operates with the horn pad, but no horns, so maybe bad horns.
The fuse may also have been removed if it had that bad horn pad issue and going off on its own.
I just recently put a new battery in my 2000 Porsche Boxster and now my radio is requesting a 4 digit code. It is a cdr 220 radio, Becker 1. Type 4462. And the serial number is y5043037. Please HELP if anyone knows how to remedy this. Thank you!
