    I don't know about the Durametric, but with a PST2/PIWIS you can check the brake light contacts in the DME Input Signals. There are two sets of contacts in the switch - one normally open, and one normally closed. Just checking that the brake lights are working isn't enough.

    PSM isn't connected to PCM at all.

    2004 would have the fibre-optic MOST bus, which is much more difficult to update with an aftermarket device. Try a search, and you will see how others have overcome the problem, but it usually involves changing the amplifier as well as the head unit.
  4. Richard Hamilton
    It is in the special tools catalogue:

    The retail price of these units (according to the price search here) is £391. Would it not be worth trying Sunset (Porsche Parts at Dealer Cost link), as they are usually cheaper? As Loren says, you need to find someone who can program it correctly first. If you end up having to go to a dealer you might find they may not look favourably (price-wise) on programming a unit you have bought elsewhere.

    The workshop manual makes it sound easy enough: 19 78 19 Removing and installing coolant temperature sensor The place of installation is at the left front in the direction of travel, in the area of cylinder 4. Removal 1. Remove rear underside panel. 2. Pull off electrical plug connection. Undo temperature sensor (wrench size 22). Installation 1. Check sealing ring and use a KD (service) sealing ring if necessary. Note As standard, the temperature sensor has a captive sealing ring. Tightening torque 25 ± 5 Nm (18 ± 3.5 ftlb.) I would be tempted to get a diagnostic check done first though. Don't want to be barking up the wrong tree.
  7. Richard Hamilton
    I think it would. A diagnostic check should show what's wrong if it is the temperature sensor which has failed.
  8. Richard Hamilton
    Four functions of the coolant warning light: 1. Engine coolant level too low — light flashes slowly (0.5 Hz) 2. Engine compartment temperature too high — light flashes slowly (0.5 Hz) (engine compartment blower might be faulty) 3. Engine coolant temperature too high — light is lit; pointer on the right 4. Temperature sensor at water outlet faulty — light flashes rapidly (1 Hz); pointer on the right Note The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously (1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash) So it might be the temperature sensor is faulty (if the light is rapid flashing).

    I got the P409S kit. I just looked up the invoice, and it was $120, plus some extra stem spacers and hollow screws for the metal valves on my hollow spoke Turbo 2s. I posted a picture of the modification on a thread on the 996T forum around January/February time. Again, not required for conventional valves.
  10. Richard Hamilton
    When you lock from the passenger side you are physically turning the lock barrel, but when you lock from the driver's side the passenger side is locked by the lock motor. Therefore it would seem logical that the passenger side lock motor is at fault. The reason that the the driver's side locks and unlocks (from single-locking with either side key) is that the system sees a fault (ie the passenger side is not locked) so immediately unlocks the car. Triple-locking tells the system to ignore the fault and lock it anyway.

    I fitted the Orange TPMS to mine. It works very well, and wasn't expensive - I bought direct from Orange Electronics - around $120 IIRC. On the turbo I had to modify the metal valve stems in order to fit the sensors, but that wouldn't be required if you have rubber valves, It is useful as a safety aid, and for setting the pressures accurately. If you do track days (DE days?) it would be invaluable, as you can monitor temperatures and adjust pressures accordingly.
  12. Richard Hamilton
    That is correct. They stopped making the one which fits by the siren, and the replacement unit fits next to the alarm module under the left handset.
  13. Richard Hamilton
    The alarm module is coded for 'with' or 'without' tilt sensor. You should get the module coded for 'without' by someone with a PST2 or PIWIS tester.
  14. Richard Hamilton
    It is only any real use if you fit a reversing camera. Not much point in connecting it for navigation purposes.
  15. Richard Hamilton
    I have seen one of those with all pins populated, and it was rubbish. The connections were TOTALLY wrong and there was no chance of it working. The plugs are moulded on, so you would have to destroy it to get it apart. I suggest you cut the cable and splice the correct wires together. Where are you located, that the shipping was more expensive than the part?
  16. Richard Hamilton
    I know he has used it on a PST2 and it is OK. As Loren says, the PIWIS uses the older PST2 software for the earlier cars, so I think it would work. The Knock wire is for knock detection, and the TD connection for engine speed. I don't think the PIWIS would use these signals though. Where are you getting the 19-pin plug from? Do you have a link?
  17. Richard Hamilton
    Perhaps I am confusing you. When I refer to an adapter cable, I mean one like the Sensolutions/Durametric one, which converts the OBD2 cable into a 19-pin cable. This has an OBD2 Socket on one end, and a 19-pin plug on the other. I dug out my notes, and here is the schematic I used for the adapter/converter lead: Note that the 19-pin diagram is a view looking at the socket. The dotted line between pins 3 and 7 of the OBD2 plug is to join two K-line connections. In both my PST2 and PIWIS cables there is already a wire joining these two connections, so I had no need to put it in my adapter cable. I guess I should add that you try it at your own risk, but it worked for me. Edit: The PIWIS instructions list: "Diagnostics adapter cable for diagnostics lines with round plug socket" Part number: 000 721 971 81 Edit 2: I remembered that a friend of mine has a Sensolutions adapter, so I got him to check the connections. It is wired the same as my schematic, except that the Knock and TD (engine speed) wires are not connected. All the important diagnosis ones are though.

    Hi Frank. Doing fine thanks. PCM in a 2003 would be PCM2, so the Vauxhall/Opel maps won't work. Porsche released the 08.2009 maps for PCM2 a couple of months ago, btw. (edit: Maps of Europe)
  19. Richard Hamilton
    The adapter I made used an OBD2 socket, and a 19-pin plug. Using wiring diagrams from the Bosch EsiTronic system and the workshop manuals, I matched the diagnostic connections on the 19-pin plug to the appropriate pins on the OBD2 socket. IIRC there were connections for K-line, L-line, TD, Knock, 12v and Ground. Like I said, it worked on the PST2, so it should work with the PIWIS, I would have thought. I'll try to dig out my notes and post the diagrams over the weekend.
  20. Richard Hamilton
    I believe the rear trunk remote unlocking is programmable in the alarm control module (with a PST2 or PIWIS). Maybe it has 'lost' the setting.
  21. Richard Hamilton
    I can't see why the adapter cable wouldn't work with the PIWIS. I made up an adapter for my PST2 and it worked fine on the one occasion I used it! I'm sure it would work exactly the same on my PIWIS, but I haven't had the opportunity to try it.
  22. Richard Hamilton
    I had something similar with mine. I was getting a clonking noise when manoeuvring at low speed, usually on anything more than half lock, and most often when reversing. It was the shock absorber top nut was slightly loose. I found it after checking the TSB's for the 996T. Might be worth a try.
  23. Richard Hamilton
    The adapter cables for OBD2 to 19-pin are available from this Canadian company, although they are made in China: http://www.sensolutions.com/products/browse-products/porsche/diagnostic-adaptor-for-porsche/?tx_commerce_pi1[mDepth]=2
  24. Richard Hamilton
    They are different. The speakers are angled differently in the housings.
  25. Richard Hamilton
    They have to be maps for the NCDR/NCDC system. Vauxhall make other systems, like the CD70, but those maps are not compatible.
