  1. No as I discovered on Saturday when this happened. Sent from my iPad using Tapatalk
  2. Mine had a leak in the fuel line from the fuel sender. It is located under the battery tray. Fuel had pooled on top of it. Sent from my iPad using Tapatalk
  3. Thanks Loren. Yes I've gone through the troubleshooting steps in the workshop manual for the alarm codes, and everything checks out. So perhaps the alarm control module has a problem even though it looks fine and there are no signs of water incursion.
  4. Replaced the solenoid. New one has a higher resistance but does not solve my double beep/no central locking issue.
  5. I determined that the cause of my problem was Durametric not being able to reset codes. The version released on 5/3/17 has fixed this bug. Plugging in the seat belt receptacle to the wiring harness, turning the ignition on and clearing the code did the trick.
  6. In my continuing quest of figuring out my alarm double beep issue, I'm trying to determine whether my trunk release solenoid is acting up. Does anyone know what the correct resistance should be across its pins? I'm getting about 4.7 Ohms. MY02 996 Carrera 2 Cabriolet.
  7. Is the parking brake on? My microswitch failed and the parking brake light was not. Sprayed cleaner on the switch and it has been working since.
  8. Update on my original issue - there's now quite a long thread over on Rennlist about this: https://rennlist.com/forums/996-forum/988367-alarm-double-beep-and-central-locking-frustration.html Currently the bonnet/front hood/trunk latch is suspected.
  9. I removed the driver seat after consulting with my mechanic who suggested that it would be much easier. I put in the new buckle but I still have the same problem (Code 46). With the ignition set to on, and subsequently with the engine running, I cleared the code using Durametric, but it returned when I switched off the ignition and switched it on again. From the workshop manual, I measured the resistance between the buckle pins and got the correct 400 Ohms resistance, so the replacement buckle is good. 2. On the connector that comes from the wiring loom of the car, I've measured the resistance between the grounded pins that go to the belt buckle and the ground point by the alarm control unit and get about 1 Ohm. When I measure the resistance from the brown wires in the same header connector, I get under 1 Ohm. I wouldn't have thought that this difference would be enough to trigger the warning. What do you think? Sent from my iPhone using Tapatalk
  10. After working on my central locking issue and reinstalling the driver's seat, Durametric reports a driver seat belt error code, which triggers the airbag warning light (I think it is is code 45 - don't have it in front of me). Reading various threads including this one, TSB 1/04 6924 Airbag Warning Light Comes On: Fault Codes 45, 46, 48 and 49 -- dated Jul 21, 2004 is referenced. I have verified that my VIN is prior to the manufacturing modification to use the new wiring harness. I've also seen that the driver's side seat belt receptacle is "sticky". I've tried cleaning contacts, etc. but no dice. I've also measured continuity between the ground points and the appropriate pins on the connector to the seatbelt receptacle and they look good. Questions: Can I remove the seatbelt receptacle without removing the driver's seat? Do I really need to perform the wiring harness modification or might just replacing the seatbelt receptacle be sufficient? Looks like I would need to get under the passenger seat to get to the airbag module to do so properly.
  11. Car: 2002 C2 cab. Driver side latch was replaced last year as was the front hood latch. Symptoms: 1. Double beep when I try to lock with the key fob, and locks to do not lock. 2. Central locking switch LED on. 3. Unlock possible with key fob. Using Durametric, I get the following codes: 47 - Control locking synchronization 60 - Central locking limit position Lock not reached61 - Central locking limit position Unlock not reached Here's what I've done so far: 1. Assumed it was the passenger side latch causing an issue and replaced it. No change, so put the old one back. 2. Removed driver's seat and removed and inspected alarm control module (exterior and interior). No water incursion found. Circuit board looks OK: no burns or visible defects. 3. Followed the Bentley and Porsche workshop manual troubleshooting for these error codes (Workshop Manual is far more useful). No issues found. 4. Reviewed the schematics and tested continuity to ground and continuity between driver side and alarm module and passenger side and alarm module. No issues found. Put it all back together and initially it seemed fine. Then it started to repeat the double beep. At this point I'm not sure what to do... I see conflicting information about whether the exterior and interior door handle microswitches will cause a double beep or a single beep. Can anyone advise? I'd rather troubleshoot these than sending off the alarm module, DME and keys for diagnosis, which seems to be the next step according to the Workshop Manual. I now also have an airbag failure light supposedly caused by the driver seatbelt receptacle. Will post separately about this.
  12. Yeah it was. Used one on the end of a ratchet wrench to get to it. Fiddly.
  13. I'm trying to diagnose alarm/locking issues and want to undo the electrical connector between the door and the body to test wiring continuity. This connector has a rubber shroud for weatherproofing and this is connected to the door by a fastener. Due to the position, it is difficult to see what type of head this fastener has (hex, Torx, etc.) Does anyone know? I tried the imprint in my fingertip method, but it wasn't very conclusive.
