The 997 was never fitted with a reversing camera, and I don't know if it has the (Fakra) input connector or if the coding  option is available.  Several people have retrofitted them to the Cayenne which also uses PCM2.1.

As a first step, I would check that the PCM unit has the input connector, and get it plugged in to a PIWIS tester to see if the coding option is available.  Here is the rear view of a Cayenne PCM2.1.  I believe the camera is connected to "K".

You can buy a set of replacement buttons for the Gen1 keys which makes them less prone to accidental operation.  They aren't cheap, but are effective.  Another option is to buy a used Gen2 key head case and swap the internals.  There are also aftermarket Gen2 key head cases available.

Fob works.

Dash button yields same result.

Fuses good.

I'm confused. Sorry.  When you say the fob works, and the dash button yields the same result, do you mean that the system locks and the immediately unlocks?

As wyovino asks, did you fit a complete new passenger door lock mechanism?

Is the fob working at all?  Does the button on the dash lock the doors?  If not, check the fuse on the alarm unit under the left hand seat. (Between the 2 plugs - 15A). Also check it isn't wet under the seat.

If you are removing the PCM the individual memories should be retained.  To change them in the future, you can have it done by someone with a PIWIS tester (or maybe Durametric Pro).  They are stored in the Key settings in the PAS module.  You should still be able to change the DRL setting through the OBC.

You should really have the other modules re-coded to remove the PCM, Phone, CDC, etc from the Gateway controller.  If you don't, you will get all sorts of CAN communication errors between modules.  You won't see them yourself, but any techs trying to diagnose a problem at a later date will be tearing their hair out trying to figure out what is going on.

The 986 Boxster uses a transmission based on the ZF 5HP19 transmission used by VW/Audi/BMW as JFP says.  Any good transmission shop should be able to fix it.  There are on-line parts catalogues for the ZF 5HP19, but if you have trouble finding one drop me a PM with your email address and I'll send one I have in PDF.  Just Google and you'll find lots of info.

I'll wager it is one of the microswitches inside the door lock mechanism (there are 5 switches inside, in addition to the switch on each handle).  The door lock can't read the one which says it is locked, so immediately unlocks.  Or it could be the switch which senses that the door is closed (thinks it is open), causing it to unlock immediately.  Triple-locking with the fob or key will force the system to lock, but it is only a temporary measure.

As Loren says - clear the codes and see which ones come back.  13, 14, 59, 60 & 61 are the clues that the microswitches aren't reading correctly.

Of course, it depends very much on the previous owners driving style and location, but in the UK we would reckon that 30mph would be a reasonable average speed.  A heavily tracked GT3 might be higher, and a London-based Tiptronic model somewhat lower.  If you can find someone with a PIWIS, or up to date Durametric Professional local to you, that would be the certain check.  There is a registry of owners in the diagnostic section, and I'm sure any one of them would help.

Richard, That link closes the thread. It's all the info anybody could want to diagnose the issue. I'll try to check every switch and resolder the joints. if that fails I'll buy a go to an indy to detect the actual part to replace.

 

Thanks for your help.

 

Last point and I'm sure it's related but the little lock switch on the centre console is always on. I'm new to Porsche kettles so I'm not sure if that is correct or not but it doesn't go off.

 

 

Quite possibly, because if the alarm module still thinks the door is locked, I suspect the switch light will stay on.

You don't say what model year the car is, but if you look up the part number for the door lock you may well find it has a VW part number, and you can often find genuine new ones on eBay for around £30-40.  Some use the lock from a Mk 5 Golf, but you are better searching by part number, to be sure.

You can download the parts catalogue from here: http://www.porsche.com/uk/accessoriesandservice/porscheservice/serviceandorgininalparts/originalpartscatalogue/

If you are "my" side of London, I'd be happy to plug my PIWIS tester in for you.

Not exactly, but you are on the right track.  There are 5 switches inside the lock mechanism:

1) Key to the lock position

2) Key to the unlock position
3) Door open/closed

4) Lock motor has reached the unlock position
5) Lock motor has reached the lock position.

Dry joints on the circuit board where the switches connect are another common problem, with the same effect.

A double beep is a system fault (a single beep is an open zone).  The most likely culprit is the microswitch inside the door lock mechanism which senses that the lock has reached the unlocked position.  Of course, it could be either the driver or passenger lock.  Best bet is to get a diagnostic check done which will show what the fault is, and which side.  The microswitches inside the door lock aren't listed separately, so you have to change the complete lock mechanism.

DME7.8 is the same as used in a 2004, so it should show the mileage.  I'm not sure what you mean by "Durametric 20", so it might be an old (or clone) software version.

A 2004 996 should record the mileage in the DME (in kilometers), along with operating hours.  You should be able to read this with a PIWIS tester, but I'm not sure if the Durametric will show it or not.

It all looks a bit suspect to me. 

18000/580=31kph average (19mph).  For a GT3?

The airbag module reads 830 hours.  This starts counting when the ignition is switched on, whereas I think the Operating Hours counter in the DME (580 hours) records the engine running time.  You would expect a discrepancy, but 250 hours?

And the ignitions in rev range 1 only 79, 22 hours ago?  It is a GT3 after all, and you would have expected some slightly more spirited driving than that during its life, assuming it is manual transmission.  Even my Cayman 2.9 PDK had some in rev range 2.

There may be a plausible explanation, but unless the seller can provide one I would be very suspicious.

Welcome Elliot!

The batteries for the tyre pressure sensors are integral to the sensors, in the wheels.  You have to change the whole sensor.  As it is 8 years old, and the batteries have a life of 7-8 years (at best) then you would be best replacing all four.

Bluetooth was introduced with PCM3.0 (in MY2009), and you likely have PCM2.1.  There are some good aftermarket Bluetooth phone modules available for 2.1.  Google ViseeO Mosto, or NAV-TV Tooki.

Running that software version, I'll wager it is a clone Durametric, in which case that is probably your problem.

Depends on how it is flashing:
 

They are the original dome nuts which were used on the 987/997.  It was the 986/996 which had the security nuts.

The new airbag control unit will need coding and locking with a Porsche specific tester.  I note you have a Durametric Pro, but check that it has the function to lock the unit after fitting.

A new Airbag Control unit also needs to be locked as well as coded.  Not sure if the Durametric will carry out the locking process.

Drop me a PM with your email address and I'll send you some detailed instructions and a wiring diagram.

It sounds like an alignment issue to me.  If you haven't had it done, get a good 4-wheel alignment check, including ride heights.

Each door has its own control module, and are coded independently.  I'm assuming that it has never worked with one-touch.  If it just stopped working, then you may be correct about the motor.  Just another thought - you haven't had a flat battery, or replaced it recently?

I think you need to find someone with a PIWIS or Durametric Pro, and look at the coding in the passenger door control module. Check that Comfort Closing/One touch. is activated.
