My 2011 cayenne turbo had a similar problem with the pcm would reboot and after I replaced the battery it has not done it. I replaced the battery about 12 months ago. Never got Battery protection warning though.
I do not think I fixed this issue but it is working for now. I made my first post after a lot of internet searches and brainstorming with the car. I started listening to some of the sounds the locks were making and then I decided to hit the the lock button many times very fast (I was trying to see if I could unstick something) and one of the doors unlocked and I remembered I shot some wd40 in that door's lock actuator mechanism. I sprayed the other side and locked and unlocked several times and it works at least right now. I am thinking that this might be a sign that both actuators will need replaced at some point but I hope not.
2011 Cayenne Turbo. Battery is approximately 1 year old. I have searched a bunch of similar threads but have not come across one that has a fix when both rear doors are not unlocking. The problem is that both rear door do not unlock via remote, pressing the unlock button in the car or from turning car off. The only way to unlock the door is by using the door handle inside. I thought that I may have had a bad actuator but it would be quite strange to have both doors quit working simultaneously. I also did a scan with my Icarsoft scan tool and came up with a code 000843 Central locking closing unit. Anybody else had this issue before? Any Ideas?
I had a similar problem recently. I had to replace the alarm module. About $150 and it is located on the middle of the firewall. I am 6’1” and have long arms and I still found it a pain to reach it. Several tutorials on the internet. Follow the steps in exact order it will help (ask me how I know this). The part is used on several cars over the years and is readily available. Do not buy a used one. They are known to fail with age. I hope this helps.
my 11 Turbo is an extremely smooth ride in comfort mode (my opinion).
I am new to Cayenne ownership. The limited knowledge that I have of air strut system is that it needs to be filled with Nitrogen when you replace any component in the system. This filling process also requires the use of a PWIS computer. I think if you had a shop with a PWIS refill and calibrate the system you would get that great ride back. I hope that helps.
2003 996 cabriolet. I was putting my top up yesterday and I heard a strange noise as it was finishing putting up the windows. The sound was almost like a popping sound (not very loud). I went to open the door (drivers side) and the window did not drop. I tried the outside handle and the inside handle and no drop. The window goes up and down fine. I have done a search and read several great write ups on micro switches and regulators, I am still a little stumped on this one. Is it a micro switch issue or possibly an issue with the top controller. I did not have a chance to investigate or troubleshoot because I had to go on a work trip. Anyone else have a similar issue? Any thoughts on this would be appreciated.
I had the same problem with my 03 996. I ended up buying the black box on ebay from a junkyard that specializes in Porsche parts. I was able to get the part that I needed and I was able to see how the box functioned to fix my blend door. The piece I needed was small and I could not find it for sale from Porsche.
I have not seen a diy for it. The system is somewhat complex (ac unit) if you can figure out what flap is not fully closing or which actuator is bad you might be able to fix the problem (if that is the problem). 2 actuators are under the passenger footwell if you move the heat from full cold to full hot you will see the actuator move. The actuators have a plug and 3 or 4 screws and they look fairly simple to replace. I will take pictures of my used unit to show you what I am talking about. I picked one up a used ac unit on ebay for $75 so that I could possibly fix flap that is malfunctioning without removing my current unit.
I would guess it is possibly the same problem. You might be lucky and it could just be one of the actuators that has gone bad. That is and easy fix. I have ordered a used ac unit to see if I can use parts from it to fix my problem. I will post an update with my findings.
Unfortunately I am reviving this old thread. The problem is back and my ac blows warm once the car gets warmed up. My actuator seems to be working ok but the adjusting lever will not seat properly. The problem flap is the one for my feet, if I leave it off it seems to do better. The best way to fix this is to order a new ac unit $1300 and probably 10hrs of labor (wild guess) the dash needs to come out. My thought is to buy a used ac unit and use that one to figure out what a working one does and figure out if I can fix mine with the parts from the used unit. I read Logray's post about his drive motor malfunction and it looks like my problem is not as easy of a fix. My cost for a used unit would be around $100 to $300 dollars. Anybody have this problem or care to share what you would do in my situation. It is hot here in Texas and I like to supplement my top down driving pleasure with the AC.
Thanks for all the replies. I am thinking the best solution would be to buy the white faces and send them along with my cluster to Palo Alto speedo shop and let them put them on and recalibrate everything. The mileage thing is definitely not something I want to mess with. Thanks again. Jim
I have a 2003 996 C2 Cab. I would like to put white face gauges on it. Stickers do not appeal to me. Opening up the cluster to replace the faces sounds scary (if I go this route I will send it out to be done). I located a used cluster at a dismantler part number 996 641 984 93 it is out of an 02 turbo(6spd). My question is will it work in my car? Do I need PIWIS do reprogram it for my car or can I do this with my durametric? If you converted your car to white faces How did you do it? Did you have any problems? Looking for opinions and options. Thank you in advance. Jim
av8sky replied to mrrogers's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Used engines are available for the MKII. My insurance company found one for me about 6months ago. I believe you can find them for the 8-10k range. The sources JFP listed in that link are really good. Oklahoma foreign and 20th street are really good sources. I have bought some things on ebay from a seller named qualityporscheparts. I think he was parting out an MKII and he might still have the engine. If you look hard enough you can always find your part.
I was out for a drive yesterday enjoying an unseasonably warm and humid day here in Texas. I turned on my window defroster (by mistake) all of the sudden my nice cold AC was very hot. Even when I turned the air off it was throwing full heat at me. The first thing I did when I came home was look on Renntech. I saw a few things but nothing that said here is your problem, here is your fix. This is unusual because this site always has all the answers. I read my Bentley manual (great manual btw) It mentioned testing the temperature control flap motor. The Manual did not say how. The answer is Durametric or piwis is how you test. I also saw a post somewhere about somebody having a flap slip the shaft causing his ac not to work properly. Today I crawled under the dash to see if I could find this flap/flap motor. I found it and saw that spot where the actuator hooks up to the flap did not look right. I played around with it for a little while. Three pieces need to be removed and put back together so I could get the actuator to work properly. I turned the car and I have nice cold AC again. As I was buttoning it all back up it occurred to me I should have taken pictures. If what I did was just a temporary fix and I need to replace parts I will take pictures and list part numbers. I did not see any damage and it all went back together nicely. I think it was because the heat had not been used in quite a while that the flap was stuck and the actuator slipped. The car is a 2003 C2 cabriolet. I feel very fortunate that I have this site and it's members. You have all saved me lots of money. Thank You!!! :renntech:
