Of course rhis only happens on cars thst support reading out the vin# from the ecu - IIRC the 964 does not so you can use Dura on as many 964's as you like.

Does he by chance have the auxiliary battery installed? Check for that, in the event there are two batteries, only changing the drivers seat one isn't always enough. Also check the main relay on the power panel under the drivers seat - on the power distribution panel. Also there are 2 fuses I think on there with the relay. Can't miss the relay - one single black cube with "433" or similar printed. It should audibly click if your ear is close enough. If you don't know how to test it with a multimeter, I believe it is identical to the starter relay in the relay panel under the hood on. Verify it's the identical part and swap out to test quickly. This kind of troubleshooting is tedious but best if you just start at the battery and go step by step away from it.

My plastic arm im flex mode. Not good.
Close up of the relays
Board reinstalled in housing with position arm at full extension
Diagrams. Lock has three wires. CAN high, CAN low, and data. The high and low are the source power for the 12v motor, low current here can cause problems.
Straight on shot of the hall effect sensors. No cheap microswitches like VW.

Turns out it wasn't the issue with the ELV, well now it's on emulator, I guess one future issue resolved in advance.

for MY08 Cayenne with proximity keys, this particular issue lies within the KESSY module where it goes out of sycn with the ELV, NO ERROR on dash and scanner will show 0288 steering column lock error, but if you have a ross tech cable it will call out - 00288 - Steering Column Lock Actuator (N360): Implausible signal. according to Tom, this usually happens to MY08 Cayenne that has proximity key with a particular serial KESSY. Now the usual fix is power cycle the car or simply remove the fuse for KESSY for 30mins, this will allows the 2 modules to resync properly. However it didn't work for me the first time. My gut feel is it has something to do with the proximity key in pocket which triggers the KESSY to ELV check too early and not allowing it to resync ~ (just guessing here)

I end up doing the following, a lot of the steps are useless i think, but I want to cut out some variables to avoid needing to go through the cycle again.

ELV is removed from car at this point

1. Remove kessy fuse (41 - Right side) / power out for 1hr
2. Plug ELV in socket and leave door open (I notice that every time door is opened, it triggers Kessy to talk to ELV when I had the ELV unplugged and shows error on dash)
3. Put fuse 41 back in
4. Try start car with dummy key, with proximity key away from car, at this point it’s showing no key found
5. Bring proximity key and try start car with dummy key, still doesn’t work
6. Remove dummy key and try start car with real key, it works from this point

I really hope this will help some people out there, also thank you Ben and the rest of the forum who posted their steps trouble shoots etc
