Has anyone actually replaced the front sunroof drains on a Cayenne? I've got a 2003 Turbo and like many of us, have had a clogged sunroof drain and a lake underneath the front carpet. I removed the front seat and peeled the carpet and foam back and let it sit in the sun for a few days and it finally dried out.

When i started inspecting the drain, i noticed that mine has a flattened area where it turns downward from underneath the headliner to down the A-pillar. It's still clogged at the end, but i need to replace it because it is too stiff to return to its original round shape.

Where do the drains actually exit? I removed the wheel well and i see one drain that i can stick my finger, but i believe this is the cowl drain based on other photos. Does anyone have photos depicting the different drain locations (i.e. cowl, AC evaporator, sunroof drains).

I've read a lot of the forums about cleaning the drains, but haven't seen any dealing with replacement.

Any help would be much appreciated!

first question.....no they don't sell the idividual hose barb drains.

Front drains go down to the firewall and then just dump into the sheet metal cavity between the passenger compartment and engine bay. The drain you can see with the wheel well off, is the exit of that cavity.

A semi easy way to get down there is use weed wacker string.....and just feed it it through the tube.....it takes some practice to get it all the way through, but push and turn a bunch of times and you'll get it through.

      Hello all
      I'm hoping someone out there can help an electrical novice with my daily drive.
      My car has recently developed a non-start issue. I have the wet carpets problem that so many 986s seem to suffer from. Initially I thought I had fixed the problem with new door liners but it seems my problem may be elsewhere - probably blocked drains.
      Either way, my car failed to start last week. The central locking doesn't function, interior light is out and the motor doesn't crank. I removed the alarm unit from beneath the passenger seat (RHD UK car) and there was some slight corrosion on the circuitry. This cleaned up ok after a isopropanol bath. However, the no start issue remained after plugging the unit back in.
      At this point it seems like a simple blown alarm unit. However, I unplugged and replugged the unit a few times and eventually the interior lights turned on again. The motor cranked in to life. I used durametric to check the alarm module - P1571 Immobilizer: Open circuit or no signal. The unit responded to various test through durametric but then stopped responding after a few minutes. I turned off the ignition to attempt a restart and nothing - back to square 1. Even when the engine was running, the central locking remained deffective.
      Before I spend a probable fortune on a new alarm module, is there anything I can check? It seems weird that the unit functions some of the time after plugging / unplugging multiple times. I've sprayed contact cleaner into the plugs for the alarm module in case it's a connection issue. The Durametric error indicates to me no power is getting to the module - correct? Is there any way to simply remove the immobiliser?
      Any help would be appreciated as the thought of a 30 mile round commute on a bus does not appeal!

      Okay this is more than likely my fault for not getting my bulkhead drain grommets sorted out properly last autumn (they were blocked and causing water seepage into the cabin but when I was trying to clean it out I managed to push the old n/s grommet into never-never land.l bought a replacement and then did the same again! (To be fair it is a ba***rd to access as you'll know if you're familiar with this). I intended to try and access the never-never land area by removing the inner wheelarch liner in the Spring - by the way, as a separate issue, does anybody know if that will allow me to access/ retrieve/ refit the damned grommet?

      Anyway, onto the current issue.......the passenger carpet got wetter than I realised and although the ECU/ alarm unit seems positioned high enough away from the floor under the seat and is not covered with the carpet, I'm guessing that this has caused the problem that I have now. I.E. The central locking won't work now and only the drivers door can be locked with the key, plus the battery drains completely overnight.

      I took out both the passenger seat and the carpet to have a look, but although there was some water (not that much as there is a small hole drilled in one corner acting as a drain!), the ECU/ alarm unit appeared to be dry.

      Having tried to find a solution on various forums/ searches, I haven't seen this fault replcated or explained anywhere else, although my thinking is that it is actually the ECU which is the problem due to moisture ingress?

      Anyone know if I'm right and if it is the ECU, what's the best solution please, repair (how?) or replace? I've read some stuff about a reprogramming issue with new units?

      Any help much appreciated.

      Cheers,

      Tony
