  1. Okay then I don't understand. The locking chirps are made by the alarm siren. I'm talking about the locking chirps - I think Johnny is too. [sorry - I wrote "alarm chirps" - now edited]
  2. Loren, two alarm chirps is correct when the car locks. see page 20 of the 2011-2012 Cayenne manual - extract below.
  3. Johnny, Mine used to chirp maybe once, and only sometimes do the hazard-flash. Then it got worse and stopped chirping, hazards flashed immediately and all the time. The guy on the closed thread replied to me privately and said "Replacing the Siren with a new one (I think the new one part# ended in D) fixed the problem" Having now held a bad alarm-siren in my hand and felt the (lack of) quality, I'd definitely make that the first thing I'd change. It's in a vulnerable place (underneath water streaming down off windshield) and has its connector facing up into the flow.
  4. By the way - re-reading above - huge thanks to Don and I especially endorse his suggestion that I try a different diag, tool to Durametric - I should have asked the Porsche mech what he used but maybe it was the iCarScan that Don proposes. Anyway, I would have nailed this 10 months ago with a better tool. -Richard
  5. 13 months after originally requesting help with this problem - I fixed it today. The car eventually got to the point where, when you used the remote to lock the doors, they would lock (one exception described below), then the hazard warning lights would immediately flash and do so forever, or until the battery was flat. There was no beep from the alarm system. One other clue was that the left rear door failed to lock, you could always open that after locking the car. I had a new lock actuator fitted - that cured the door not locking, but not the flashing lights.
  6. Well as I stated somewhere above "anything that is 'fixed' but you don't know how/why...will come back to bite you" - and of course, it has now come back, only worse. Completely predictable. latest code reading session was very clean with the exception of this one: BCM Rear 4639 / 121F Warning Indicator On Test Not Completed blabla... Fault Active That code persists after any attempt to erase it with Durametric. Googling that code gives no results whatsoever. Is there a master decode list somewhere for all these codes? - maybe only the dealers have
  7. Wow, Don, thank you - this is going above and beyond. I have played with the gas cap quite a lot. I've done things like, locked the car while leaning on the cap, locked while pulling outwards on the cap. Made no difference, but your experiments make me want to persevere with it. I take your point about that being the only "clicking thing" in that area. I know what you mean about the complexity of the lock - also strange the way you can do the push the cap while locked, then unlock and the cap pops out without touching it. Right now the problem is...it's
  8. Thanks again Don. Yeah I'm confused by the Durametric at the moment - 2 reasons: - no way of understanding the codes - google them and find no info at all - do you mean with a different tool it might interpret the codes for me? - communications failure when I try to clear, for instance, the door or seat codes. Then have to re-start the software etc. (and tell it AGAIN which Porsche I have and that it's a V8) I've only had it a month, do I really have to buy another one? :-) To answer your other question, yes I'm pretty sure the fuel-flap is okay, I've tried locking with it
  9. A new problem: Every time I lock the car, after about 30 seconds, the hazard warning lights start flashing at normal speed, as though I hit the switch on the console. Other clues: - there's a fast ticking from behind the gas-cap - faster than the flashing cycle. Is that where the rear BCM is mounted? It's louder inside the car - the rear tailgate lights come on solid - the ones that illuminate below when the tailgate is open, they're on inside the car with it closed - unclearable fault on the BCM rear with Durametric 3615 / E1F Warning Indicator On
  10. Yes I bought all 8 from Sunset Porsche. The problem has never re-occurred. Good luck, -Richard
  11. Hello, and thanks for the reply. On another forum suggested the bad-coil idea - and there was one code which suggested a misfire on cylinder 5 - that cylinder was therefore shutting down and the car running rough until I cleared the code. I changed that single coil, and the car hasn't had the problem since - therefore I changed the other 7 coils. It seems that changing coils should be a service item - everyone who's had the problem sees them failing at about 70k miles like mine. Thanks, -Richard
  12. Thanks Loren - the car starts like a champ, really cranks over fast, so it hadn't occurred to me it could be the battery. But I see what you mean. I'll take a look at the ground cables, then change the battery. -Richard
  13. I'm confused by a fault that keeps appearing on my 2011 Cayenne S. 71,800 miles, I've owned since 70,500 with little history known before my ownership. Therefore sorting through the usual new-owner issues. I'll illustrate with an example. - Last night, car was running perfectly, had been fine for about 150 miles - connected Durametric and saw no codes under engine, PSM, tiptronic, AWD etc - this morning - 60 mile roundtrip - about 3 miles from home suddenly car feels like it's running rough, maybe on 6 or 7 cylinders, dashboard alternates between "Check Engine", "PSM
