Where is the Alarm Siren in a 2011 Cayenne Turbo?
Mine went bad. When I lock it, the hazard lights get activated non-stop until I unlock the CTT. LED front and rear lights are bright enough for neighbors to complain at night.
Part #: 1K8951605B
1) It is not under the fuse box in the engine compartment. I already did the hard work following a 2003 Cayenne Turbo service manual I have from my old 06CTT. Wasted time.
2) I obtained a service manual for the 958 Cayenne (10,000 pages in .pdf), and it mentions it is is under the windshield wiper motor, but I went on the hard labor without validating that the service manual specifies All Cayenne except: Turbo, GTS, Turbo S, and a few others. The illustration shows a small alarm siren which seems to be what Porsche installed in the base Cayenne (the one with the VW Golf VR6 engine).
My parts manual list my CTT part as 1K8951605A, but the part was superceded by 1K8951605B. I'm trying to locate it to disconnect it, while I buy a spare part. There is not a single fuse for the alarm siren, or I would have taken that path.
Thanks a lot

...I have spent long hours disassembling and re-assembling my 2011 Cayenne Turbo looking for where is this part, and I can't find it.
As soon as I lock it with the Remote, the hazard lights go ON.
Any links to a 958 Turbo workshop manual? This is a $1,200 repair at a indi shop, and likely more at a Porsche dealer, for a simply faulty italian part sitting in my German SUV. Apparently, this is the Takata of alarm systems, as Skoda, Toyota and many other brands use this Cayenne alarm module.
Thanks.

From the manuals - it appears to be under the cowl panel that the wipers come through below the windshield. Haven't had that panel off - but there is lots of stuff under it like fuse-box, brake master/booster, wiper stuff.. doesn't look awful to remove - wipers have to come off and the rubber gasket between it and the engine compartment (which I replaced today since I tore a hole in my old one accidentally. The part was super cheap for a Porsche part - about $14 - 10-minute job took over 2 hours and involved laying on top of the engine. I'm not as young as I used to be - and some things just are a PITA..)

Thanks for the PM and this reply as well.
I will give it a 4th attempt to install, snap a few pics so no one has to endure the little pain to replace this Italian piece of plastic.

Update:
For the 958 Cayenne (2011-2018), the alarm siren is located below the front windshield wiper motor. Humidity and heat are the main factors to cause this Cobra alarm module to fail. In my Cayenne, it will cause the hazard lights to go on when locking the SUV. The chirp sound from the alarm when locking was missing due to the faulty part, so I could not locate the module.
It was easier to remove the mounting bracket for this alarm module (two 10mm nuts), then unbolt the module from the bracket (13mm nut), than trying to do the 13mm nut only.
To remove the wiper arms, I used an extracting tool sold by any auto parts store.
To remove the plastic cover that goes below the windshield is a little tricky. Pull up (straight up) from one corner with enough force, it will pop out, and it will be very easy to remove once it pops out from the rail.
The whole work should take around 2 hours knowing what to do and having the right tools. The wiper arms have a 16mm nut (you need to remove three of these). The wiper motor and moving mechanism use the same star key on 7 bolts.

Probably also a wonderful time to clean out the drains at the bottom of that cavity..
Also did some Googling - found the B variant has been replaced now by a C variant, and in the VW world - which uses the identical module - they're up to F.. The other odd thing - the Porsche MSRP for it is $3 cheaper than VW's. And a few discount Porsche dealers have it for about 20% off that price. Roughly $160.

Thanks again!

Did it work after replacing? I only ask because I had to enable mine with PIWIS. When I got the car, it never did the sound when locking.

Bought a used one from an Audi on Ebay that matched the part number. The 958's don't have the pin hole to take off the wipers. Hardest part of the job was getting the siren off with the 13MM. You might have to get into the engine bay like I did. Hard to reach from the sides. CTT was locking, then continually flashing with no sound. Never shut off.

I know many have bought used parts for this job, but if youre looking for new old stock, this is the cheapest Ive found
