  1. AS JFP says, there are several options for DRLs which can be set with a PIWIS tester in the Front Control Module. Here are a couple of the coding screens for the 997.2 in PIWIS. The 997.1 will be similar, but it should give you an idea of the possibilities:
  2. As far as removing the seat is concerned, you won't have any airbag problems with a UK 996. The seat buckles are not connected to the airbag control unit like they are on a US 996. Edit: Also, before disconnecting the battery, you can switch the ignition on, and then switch it off again, but you must leave the key in the ignition. The alarm siren is signalled by the loss of the Terminal 86S supply, and this supply remains on until you remove the key.
  3. I would email Durametric, to see what they can suggest, but I think you would be best finding someone with a PST2 or PIWIS tester. It should not matter if the wiring & stalk are in place or not, you should be able to code it. I have done it both ways, and it has always accepted the coding. However, I prefer to code it after everything has been wired up, so that I can check all the connections and switches with the Input Signals menu on PIWIS.
  4. Coding is where settings are made in the control units to tell the car which options are installed. Very occasionally, perhaps after a battery disconnect/change, a unit can lose its settings. The screenshot below is from the Gateway coding page for a car with PCM3, but the principle is the same for PCM2.1. Another thing they could try is running the Handover Routine with the PIWIS tester. If any units have slipped into transit mode (again, after a flat battery, etc.) it will wake them up. However, if you have a wiring issue, it would be better to sort that out first. Putting the optic loop in place of the phone module would have eliminated that unit from the MOST loop, so I suspect your issue is elsewhere. Either more than one external unit is at fault, or maybe the suspect earth is on the main PCM unit? It is unusual to get corroded connectors on these units, but being a cabriolet, I wonder if it has had a leak at some time and the phone module has got wet.
  5. Did PCT check the PCM coding? It would be worth getting them to check that the "Required" and "Actual" coding values are the same. And, as has been said before, check that all the installed units are coded in the Gateway module.
  6. To use the latest map disk in a 2005 997, you have to update the operating system software. The updates contain an update to the amplifier software, and the early Bose amps aren't compatible. When you run the update on such amps, it turns them into a brick. (Only of use for building a wall.) The part numbers of the two amplifiers affected are 997.645.333.04 and 997.645.333.05. Amplifier number 997.645.333.06 can be updated, but according to one TSB I have, it has to be updated using a PIWIS tester. Just something you should be aware of. Yes, if it ejects the CD magazine, the fuse is good.
  7. You did well buying an amp for £90. Make a note of the part number, and be careful if you ever update the PCM software (firmware). Early amps can be bricked if you try to update them. There are ways round it though, using a special update disk.
  8. If you put the loop in place of the amp (assuming it is faulty), all the messages should go, except for "no sound". The other systems should start working, albeit you will only have control, but no sound. At least it would prove a point, without spending £200 on a used amp and finding nothing is wrong. Here is a cheaper one: http://www.ebay.co.uk/itm/282264819294 You can get them even cheaper if you buy from a Chinese seller (and wait). You need the female version.
  9. I would suggest getting a MOST loop and putting it in place of each unit (phone, CDC, amp) one at a time to see if one is faulty. For example, the CDC has an internal fuse, and if it blows it breaks the MOST circuit. You can get them on eBay for a few pounds. Search Porsche MOST loop.
  10. Just another note on coding. If you have an Anniversary Edition (Order Code 986420/986421) do not enter that code, as it won't be accepted. Use 986320/986321 and it will work fine.
  11. I think your problem is only with the coding. The instrument cluster and DME can be coded without any wiring connections. Make sure the order code is stored in the DME vehicle data first. Then go back and do a complete control module search before coding the cluster and DME. I'll PM you the wiring diagram.
  12. This is what the diagnostic manual says, but it isn't very helpful as it doesn't pinpoint the problem. 8008 Diagnosis information POSIP Driver's front airbag Diagnostic conditions: * Ignition on * Internal function test completed Possible fault causes: * Short circuit to B+/ground/between lines or open circuit in the lines * Connection with other ignition circuit * Contact unit faulty * Driver's front airbag faulty * POSIP triggering unit faulty
  13. The heated seat relay under the seat is the same for both sides. Part number 996.618.521.00 at a whopping £160.61 inc. VAT from Mr Porsche.
  14. Sounds like a bad installation to me. As PL says, it should work on all models back to the '90s.
  15. It may seem obvious, but have you carefully checked the plugs are properly connected? Sometimes they look OK but are not seated correctly.
  16. I sent you an email. You can modify the update CDs so that they only update the modules you need - I sent some instructions.
  17. I find it very strange that there is a tick by the navigation software, and that values are shown, because you don't have the navigation drive installed. The amp, CDC, and phone modules are from your old PCM2.0 system, so that probably explains the warning triangles. I think it would be risky trying to update those 3 modules, and you won't get any increased functionality. If it works, then I would be tempted to leave well alone. Many people experience the warning triangles, without having problems, and just ignore them. The update disks are all for software 1.0 to 3.0 so I don't think they would work anyway, or might even downgrade the PCM main unit. I can let you have them, but it would be entirely at your own risk. PM me your email address if you want them.
  18. I assume you have coded the Gateway to remove Navigation, because you need to do that if you haven't got the DVD navigation drive. That being the case, I expect that is why the compass feature isn't working. What are the "Actual Software" versions (firmware versions) of the units you have installed? The Actual Software versions will be different from each other anyway. If it is a Bose amp, and it is working, it would be dangerous to try to update it with the update CDs. It can brick it. If you aren't using the navigation module, then there is little point in updating the system. You only have to do it to use the latest maps. I have a set of update CDs, but the update process depends on the software levels of the installed components. Also note that early PCM units can't be updated to 4.1 anyway - there are hardware differences which prevent it.
  19. Can you just clarify exactly what you have done? I am reading this assuming that you have removed the old PCM2.0 head unit, and retrofitted a PCM2.1 from a MY2005+ Cayenne, along with retrofitting the DVD navigation drive. I wouldn't get hung up about trying to change the VIN in the PCM coding - I don't think it would make any difference. I don't know how intelligent the system is, but your VIN would be out of range anyway. I think you need to focus on making sure all the modules are coded correctly. The components of PCM2.1 are coded in the vehicle's Gateway module, and I am not sure that the Gateway module of your 2004 car would have the coding options for a 2005 PCM.
  20. An 04 Cayenne should have PCM2.0, so it might be something else in the system preventing it from changing the VIN in the PCM. I guess the 2.1 must have been retrofitted.
  21. The genuine PSE uses a relay connected to the grey/pink speed wire on the jumper plug on Loren's image. I don't see why you couldn't fit the PSE relay, and wire it up to your system. I don't think you would be able to adjust the cutout speed range though. I have some additional information about the system which may be of use. Drop me a PM with your email address and I'll send it to you in the morning when I get to my PC.
  22. PCM3.x can be retrofitted, but it is generally a dealer job. Apart from fitting the hardware, it has to be activated with a PIWIS tester and an Activation Code.
