Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

20 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi, this is my first post-sorry if it has been covered before but I did use the search and thought I found the answer to my question but then started thinking... I have a problem with my ignition switch (2001 996tt) The information on this site says the probable problem is the plastic piece at the rear of the ignition switch, when driving yesterday the key seemed stuck and then when I removed the key the dash said key still in ignition, anyhow, I had trouble getting the key back in the ignition, so my question is would the piece at the rear of the switch (which is shared by Audi & VW) cause trouble putting the key into the slot? Any help would be appreciated before I order the part. Thanks!

POST 3Original post

Ditto. You need to replace the "plastic piece"....the electrical switch portion of the ignition.

POST 4Original post

Yes, just swapped mine out and resolved the same issue. Seems counter intuitive when you look at the part. I used the 18$ dollar switch off amazon

POST 7Original post

There are plenty of well done Diy threads on installation and the hardest part is contorting you're body and getting enough hand room to break the tiny flat head screws loose. You will curse out loud and will have cramps in bizarre places. It's a rewarding exp after you get it in there as you will realize just how much better the key in/out operation works as well as general startup. *i didn't remove the light switch I followed this guys thread to the T http://www.pedrosgarage.com/Site_3/R...on_Switch.html

POST 8 / ORIGINAL POSTEROriginal post

Well, I was a little worried after all this happened yesterday but you all seem to have this down. I'll be operating tomorrow on the switch and trust that things work out. Seems a bit silly that such an expensive car should have such a chronic problem, but I'm sure there are more where that came from.

POST 9Original post

It's a very common problem, and it's cheaply fixed. Be glad it's such an easy issue to resolve. Curious to see what dealership would charge.

POST 10Original post

Someone got it done at the dealership, carrerablue911 maybe?, and it was north of a JI oil change. eta: It was $700, but that was the whole assembly: https://rennlist.com/forums/996-foru...-spray-me.html

POST 11 / ORIGINAL POSTEROriginal post

(2001 996 tt 6-speed) There was something funky that did not make sense about replacing the electrical portion of the ignition although everyone seems feel that is the problem with the key not coming out/in, etc. I had my local, well regarded independent shop replace the entire piece with the "upgraded" part. All included the bill was less than 400.00 and everything seems to work well except when I pulled the key out the other day it said "key still in ignition". It went back in easily enough and started fine and then removed fine with no warning. Assuming everything was done correctly is there something else I should do (besides bringing it back to the shop) Thanks and sorry to plug up the forum with this- Peter

POST 12Original post

Peter: Don't take this as a criticism, I am just posting it here for people who find this thread later. It's fine to pay a professional to do the work and I don't think you were overcharged based on others who have paid to have this done. That being said, the big difference is that professional mechanics will normally change the entire ignition switch , which costs much more in parts plus is a bigger job. I would wager that 90% of the time (just my estimate, not based on any empirical data other than the postings on here), swapping out the electrical portion of the switch is all that is necessary. It is a quick & easy DIY job and all you need is the electrical portion of the switch (which costs anywhere from $11.49 at NAPA in stock to ordering online at any of the parts suppliers for about $30). It is so easy to do (once you've done it once you'll see) and such a common and recurring problem, it makes sense to both learn how to do it yourself and to keep a spare switch (along with the small screwdriver tip that is the only tool you need) in the glovebox. You never know when the darn thing will start acting up and it causes all kinds of problems. The second time mine went out on my '99 coupe, it tripped the solenoid in the frunk and engine cover release mechanism so that I couldn't open the frunk (don't remember if it locked the engine cover as well). At the time, my car was in the body shop for PDR and they needed access to the frunk. It was about 7:00 pm and the car needed to be out of the shop that night. Once I realized it was the ignition switch, I ran by NAPA to pick up the part and swapped it out in 19 minutes. Problem solved - quick & easy and for $12.50 with tax. (And it gained me mega garage cred with the guys in the shop) Now, imagine you are out in the middle of nowhere on a Saturday evening and you stop for gas. The switch acts up (which, sooner or later it WILL do, not an "if" but a "when") and strands you. You are stuck in BFE until the car can be towed to the nearest Porsche mechanic and repaired. If you just had a spare switch in the glovebox and knew how to swap it out, though, that nightmare turns into a minor inconvenience. Just sayin' - it makes sense to learn how to swap it and keep a spare switch & screwdriver tip in the glovebox.

POST 13 / ORIGINAL POSTEROriginal post

That is awesome advise, I thought that a new one would "eliminate" the problem- not so I see, so I will let the shop know and I did purchase a switch which I will keep in the car...just in case-THANKS!!

POST 14Original post

Do you disconnect the battery for this or can you leave it live ?

POST 15 / ORIGINAL POSTEROriginal post

Most say disconnect, but if you have the key out and there are no warning lights on then unplug the switch I would think that would be OK. We disconnected it, just had to re-set a couple of things afterwards.
