I replaced the ignition switch a week and a half ago thinking that the problem might be related to the switch being defective but it didn't change anything. The alarm does not turn on the courtesy lights don't work I can only open the trunks when the key is in the on position the doors lock when the engine is running. Could it be that the immobilizer went into a sleep mode and I would have to take it to a Porsche Dealer to get it going again. I have a Durametric Pro but it seems to be limited to what it does.
I got my durametric today and these are the codes that I have. Current Fault Codes 21 W lead (DME immobilizer) Status: not present Occurance Counter: 1 This fault is displayed for informational purposes, it is not an indication of a problem and no repair is needed. 10 Voltage failure at terminal 30 with alarm system active Status: not present Occurance Counter: 1 This fault is displayed for informational purposes, it is not an indication of a problem and no repair is needed. 49 K lead Status: not present Occurance Counter: 8 This fault is displayed for informational purposes, it is not an indication of a problem and no repair is needed. 45 Activation: self-activ. by radio Status: present Occurance Counter: 17 54 Radio receiver defective Status: not present Occurance Counter: 3 This fault is displayed for informational purposes, it is not an indication of a problem and no repair is needed. 60 Central locking limit position Lock not reached Status: present Occurance Counter: 7
Last night I checked the battery with my friend who is a retired mechanic and he put a load of 350 amps on it and he sais there is no reason that the battery would not start the car. Then he checked the ground wire from the battery to the body and it was good. Then I removed the seat after disconnecting the battery removed the immobiliser checked all connections then we tested the ground at the immobiliser and it is good. Reinstalled the seat after connecting everything and the battery and the car started, but still no alarm and door locks.
There is power as when I turn the key all the dash lights light up but when I press on the clutch it doesn't turn over. Now I can't even open the trunks. I only have one key but it was starting until yesterday afternoon.
I checked the fuses at A8 & C3 I put new ones in to make sure also I changed my ignition switch about a month or two ago. I did clean all the contacts on the wires before I plugged then in the board. I was wondering since they changed resistors and other things on the board do you think I have to get it reprogrammed by Porsche and could that be what is causing this issue. Thanks for your help it's appreciated.
I did remove the immobilizer I even sent it out and got it repaired I lifted the carpet dried it out like I said for three weeks but if you read my post you will see that a lot of things don't work and I also read all the threads in here and other forum and I haven't read of one that had the same issue.
I had a flood under the drivers seat a while back from blocked drains, I fixed the blockage took out the immobilizer under the seat sent it out for repairs dried out the interior reinstalled everything now my fob doesn't work, no lights when I open the doors, rear defogger doesn't work and the door lock in dash doesn't work also the flashing light on the dash doesn't work, trunk front and back only work when the key is in the on position, but the car starts. Do I have to get my immobilizer reprogrammed, or is there something else that I have to do. It's a 2003 Boxster S.
