Engine Lid Switch does NOT open Engine Lid

Hi, I hope someone can help me out! I have a 2001 Carrera Cab (996 C2) 6 Speed USA 24,000 miles. This all started when I took the car to a local high-end garage to have the oil changed. The guy call me and said he put it up on the lift and then noticed he could not open the engine lid so he could not do the oil change. I went and pick up the car and tryed the Lid release button and it did not work.

The switch opperated just fine a week before.

When I got it home, I found the emergency release cable under the left tail light and opened the engine lid. WOW... That took a while. I removed the Latch to get to the Accuator and tested the 2 wire lead that is connected to the Accuator/Solenoid. I used my volt meter and when I tested the switch i got a pulse of 12 volts. With that info I went to my Local Porsche dealer a ordered a NEW Accuator/Solenoid.

I put that in and I still have the same problem. I went to check the fuse (I thought maybe the fuse had blown) and fould the Fuse Chart was missing. I order a Fuse Chart ($16) and when I picked it up today I noticed there was NO info on Engine Lid Opener Fuse.

I am at a lose... Can anyone help... Joe

When you tested the switch was that out of the car? or was it tested with the push button by the seat?

The trigger mechanism goes through the alar/central locking immobilizer (so it is armed when the alarm is set). I think you could be looking for a broken wire or bad switch.

Get your ohm meter back out and start tracing back to the switch.

I tested the switch while it was in the Door Sill Panel... The odd thing is... I get a 12 volt pulse at the plug (end of the wire by the Latch) when i click the switch... I guess it's not strong enough to opperate the accuator... Is there a fuse or relay some place that I have not found.

Red wire should be unswitched 12 volts.

Black/Brown wire pulls it to ground when signaled via the alarm module. So, if you want to test the solenoid it would be best to disconnect the Black/Brown wire and provide a momentary ground to the solenoid.

Hi Loren, I'll try to jump the accuator to the Ground when I get home later... I'll order a new switch from Porsche today. Thanks for all your help... I'll let you know... If you think of anything else I can try let me know.

Hi Loren... The accuator/solenoid tested well... I went to Porsche and picked-up a new Engine Lid opener Switch. I put the new switch in and i still have the same problem...

Please remember this happened when I left the car at a local repair garage. Could the guy at the garage do something to the alarm to cause this issue. I left the car with the top down (it's a cab) and picked it up with the top still down, so I know the car was inside over night... I have been reading about people having problems when leaving the key in the door.

Oh... when I put the new switch in the door sill I started playing with the Drivers Seat Mem buttons... They don't seem to be working. This could be unrelated but who knows... FYI the switches do light-up with the int. light on.

Hope we can figure this out...

I'm not sure what you mean by "addon mod" but it's bone stock. Oh I do have a set of 2004 5 spoke wheels & tires.

Battery is fine... I just took it out for a 10 min. little run... I put the top up and it all works fine.

This is crazy... The switch worked fine before I took it for the service... a friggin oil changes is all I wanted.

I may just have to take it to the dealer... ugggggggg!

I meant something like Smarttop for lowering the top while moving.

Hey Loron, No nothing like that...

I did just see something... Maybe I never noticed this but, I just went out to look at it (and talk to it, lol)... The panel with the Hood Switch, the Lid Switch & the Seat Mem buttons is illuminated and NO other lights are on inside the car... I stuck my head thru the open drivers side window and look down and I can see all the little lights are all on... maybe this can tell you something.

Time to put a PST2 or PIWIS tester on the car and find out what is going on. If you were closer I would be happy to have a look.

I will...

Hey Loren, Thanks for all your help... really! This is an odd one!

Hi,

I had a similar problem with my Carrera 2 and it turned out to be a problem with the locking mechanism. Get someone to operate the lever as you push down on the lid at the same time, mine just popped open. Not saying it is the cause, but worth a try, you have nothing to lose
