Hi hazard
Check this thread for opening the front trunk. http://986forum.com/forums/performance-technical-chat/62706-how-open-hood-when-battery-good.html
I have the same problem with mine I had about 10 to 15 litres of water under the front seat from blocked drains. My board was like yours and had corrosion on it like yours. I cleaned it with alcohol and it still had the same problem but mine would start but key buttons would not work. So I removed the seat again removed the board and sent it out to a company here close to Ottawa and I received it yesterday. I will try to install it today if it can stop raining and will let you know if it works.

For reference, this eBay auction has a good picture of that module:
1998 Porsche Boxster Steering Column with Ignition Switch and Key | eBay

What I do know is that the interrogation to the transponder in your key passes through that module. That connection is required for the car to start.

a little corrosion on one of those connectors under the seat may still be the problem. I had to replace the entire connector on one of my cars, too much corrosion.

Best of luck, sir! That is a lot of water! We've been getting a LOT of rain lately here in ohio from the coastal storms in the gulf moving up north...


I was able to get access to the frunk two days ago. i now have the cable hanging out of the front so i can open it at will while still being able to close it.

My ignition switch is giving he "click" in a couple places when i turn it.. i think pin #4 on the unit might still be having issues.. I am goign to go over the plugs again more thoroughly in a few.

it seems like it's getting all the way to "just need the go-ahead" to start and that signal isn't getting there. I think pin 4 (immobilizer control) has something to do with it.. but just a hypothesis at this point.

If it is not solved today I am going to phone a friend for a durametric call. I don't want to use up his last VIN slot on his unit, so I'm trying to eliminate everything i can think of before doing that much.

I hope all of this effort resolves the issue. If not and you go to getting a new unit, get with Woody on here for used parts and also get the drivers door lock so it will match the new key too.

Is a Durametric going to be of any help though?

[hazardc]

I would hope that it might show some faults.


Going to replace the ignition switch Monday... I think I pushed it past its limits doing the key jiggle for hours over the past few days... key got stuck a few times. Best to get it out of the way, though I don't think this is the cause (hey, one can hope, though..)

[jcslocum]

I have a Durametric, I will plug it on later and see what it tells you.

Got it started!


Somewhere in between charging the battery, disconnecting and reconnecting multiple times, trying to start the car, and cleaning up the wiring multiple times, I must have blown fuse D1

It was not blown yesterday. Replaced it, car fired right up and ran like hot dog**************** for a while. Drove it for about 10 miles with varying rates of cruising/partial throttle/flogging and eventually the whole powerband came back. car feels fast for some reason (probably because it's not 90 degrees with 90% humidity for the first time in a few weeks)


Now that I'm here, any clue how to get the trunk/frunk levers to start behaving again? I don't want to have to keep a cable dangling around for every time i want to get into the front.

I can live with having a running car for the time being :dance::dance::dance::dance:



I'm letting it idle for a little bit... then a much needed checking of all the drain holes and then to the car wash.. poor car looks like poo right now, but she's runnin!
