Good afternoon all,
This is my first post but want to start by thanking all who have shared there knowledge on other posts as it has allowed me to fix various items on my car.
looking for assistance before i take the car to the dealer. i think it is down to the mobilizer but not sure if there is something easy i am over looking.
currently have a no start / no crank condition. when i pulled the car out of winter storage it would crank slow but not start.
1) Replaced the battery, still no start. Then turned into no crank.
2) Replaced ignition switch, started and ran for 10 -15 minutes; but would not restart.
3) Have 12V to pin 30 of the starter relay when key turned to start. And if i short pin 85 (from DME) to ground it cranks but wont start.
4) Replaced Starter relay with a new one. Will "click" when key turned but not hold.
5) swapped the DME relay with another one. (read a post somewhere that this fixed a similar issue for someone)
6) bypassed clutch switch
7) very occasionally (1 out of 40 to 50 tries) car will fire up. this may coincide with having the battery disconnected for 30+ min first but is not guaranteed.
? removed the control unit under the seat and when open appears to be in good condition, no moisture / corrosion. 15 amp fuse confirmed good.
9) checked all fuses in driver foot well, no issues found.
have tried both keys with the same results.
At this point i think either the immobilizer or ECU are the problem but do not have an appropriate scan tool for either of these.
can any of you recommend something i should try before going to the dealer?
i need some help, i have an '04 4.5 not turbo which has steering faulty on the dash, it's stuck in park, no dash lights, i can't get a diagnostic to work because the dash lights don't come on, i have bought a used column on eBay and switched over the wires but same fault, i have tried another ignition switch but same fault..... can anyone help?
Hi everyone, new guy here, hope someone can help?
my 996tt 2001 tip awd will not start, it turns over, I can hear the fuel pump run, I can smell fuel from the exhaust, it does not fire up. I borrowed a VDO code reader from a friend no engine issues but it has 2 fault codes under the body tab.
see images, any help appreciated cheers Paul.

As some of you may already know, we talked about designing a waterproof case for the Alarm Immobilizer Unit in Boxsters and 996s.
These units get water damaged easily if the convertible top is left open during rain, or just by the accumulation of water by the car's water drains, because Porsche installed them right on the floor of the car.
The costs entailed to repair this problem can reach $1,000's easily, that's why it would be more cost effectuve to protect the CLU to begin with.
Therefore, after many months of revisions and working with vendors to complete this enclosure, we began shipping waterproof cases last week to the members that where on our waiting list.
Below are a few screenshots of the installation video final Immobilizer Waterproof case.
If you are curious about how it is mounted here is the installation video: and PDF instructions: http://goo.gl/A9NQou
We're excited about this project and what it could mean to the Porsche community.
Please share if you know someone that could benefit from this.
Hello !! I have a mystery I need help with. My car is a 2001 996 Turbo manual.
I drove my car for 30 minutes, parked it and went on an appointment. Returned an hour later and...it would not start and ended up with a tow truck recovery. Well, having followed all the good advise on reasons and cures for non starting - my car still wont start !! New fuel pump relay, new fuel pump, new battery and new fuses. There is over half a tank of fuel and plenty of battery power. Itturns over really well but it will not fire !! Any other thoughts or potential reasons that I may have overlooked ??
