My 2003 Carrera 4s has something tricky. It's a 2nd hand car... When you open the door the car's dome light does not lit, nor the doors... But if I put the key on the ignition the it turns on, both: Dome and doors....


I checked all fuses and they're ok... A relay removed perhaps because of the buzzer or something?


Any ideas? Thanks in advance!

Did you check the owners manual and the switch on the overhead light control?

Yes I switch left right middle nothing, but door lights doesn't lit either... Just work if I put the key on the ignition

From your owners manual (available to download here)


"Switching on and off automatically

~ Move switch to center position. The lights are switched on when a door is unlocked or opened or when the ignition key is withdrawn from the ignition lock.
The lights are switched off with a delay of approx. 30 seconds after the door is closed. The light goes out immediately as soon as the ignition key is inserted in the ignition lock or
the vehicle is locked.
Orientation light
Light-emitting diodes in the doors and in the interior light improve your orientation inside the vehicle when it is dark.
The light-emitting diodes are switched on when the vehicle is unlocked and switched off again when the vehicle is locked.
Light-emitting diode in the interior light
Changing the brightness of the light-emitting diode:
-- Press switch C with a pointed object (such as a ball-point pen). The brightness changes.

Based on Loren's info above, sounds like your ignition switch is acting the opposite way. Strange indeed.

Do with a PIWIS a "Car Handover" the control box is probably lost his memory, this occurs more and solved within a minute.

Yes, Loren. I checked that several times and nothing at all... Step by Step....



Same behavior when the passenger door is opened?

Yes I checked pass door and same behavior....

I guess PIWIS then is the only solution... I spent like $600.00 on eBay for the Durametric... It's beginning to be considered to be re-sell :-(

      Does anyone know where to buy a service manual for the 997.1 Carrera? I cannot find one. I have seen a 996 manual from Bentley manuals, and there are many similarities between the 996 and 997- but there are notable differences, too.

      In the last 2 weeks I bought my first Porsche - a 2001 Carrera 4 tiptronic coupe.
      1) Is it supposed to say Carrera 4 or Carrer 4S on the back?
      2) Is there a Porsche specific website where I can find a photo of the correct rear decklid badges for each 996 model? I tried Google for 2 hours last night.
      I simply trying to determine if my 01 Carrera 4 should read Carrera 4 or Carrera 4S on the back.
      Thank you!

      I have a 2007 C2S manual with about 132K on the odometer.  A low oil pressure light has started to show up at idle after the car is warmed up.  It seems as if the light is gradually coming on more frequently.  The pressure gage on the dash reads around 0.5 bar when the light comes on.  When the car is cold the starting pressure is around five bar and is about 3 bar at 3000rpm.  As it warms up the pressure drops to about 2 bar at 3000rpm.  I always run 0-40W Mobil 1 and change the oil every 5K miles.  With the engine off and turning the key one click the pressure gage rises to about 0.1-0.2 bar.
      Can anyone help me diagnose this issue?  Would be a sensor or something mechanical?

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!
