I went and bough the maps, I was able to upgrade to v2.24, had to do a version 1.47 to 2.x upgrade, then v2.24. Went to install the maps next but it cancels out because I do not have the license. Was able to find a dealer that will charge me only for the time to install the license so probably less than 1 hour.
It is under the DME, and talks to the DME on a can drive bus. I wonder if I have moisture or other gunk in there and that is what is causing this issue... Going to pull and clean all connections this weekend on the DME and PSM.
touareg posted a topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Does anyone know where this is? I was able to catch a code today when my PSM light came on, and I went into limp mode at highway speeds. I pinout would be nice, so I can trace the can-bus wiring. DTC 1314 - DME Googling around, sounds like loss of connectivity to the DME, all other modules have not logged any issues talking to the DME. This is the last of symptoms a massive wire harness failure I had late last year, after repair this is the 3rd time this has popped up. DME has no codes, may be a red herring but the AWS advanced weight module, I have trouble talking to it and my "Passenger Airbag light Disabled" no longer lights up.
I have purchased a new code scanner, durametric is a piece of crap for cayennes that I have had. I was able to pull a code today, for the PSM, 1314 not being able to talk to the DME, it was logged when I lost power today at highway speeds. Restart or the engine (did not even have to shut the car off all the way) fixed the issue per usual. No codes anywhere else. So my PSM is either flaking, or the canbus wire is bad for it. Where is the PSM module located?
Your looking in the wrong place, for me it was easy to find, as the black wrapping had green stains from copper oxidizing, plus pushing it while the car was running caused errors on the dash. You litterally have to unwrap the wiring harness, just above the flat plastic black channel as the wires head towards the dead pedal.
If you have an early cayenne, the brake switch was known to go bad, hence why pumping the brakes works in your case. http://www.pelicanparts.com/techarticles/Porsche-Cayenne/37-ELEC-Brake_Light_Switch_Replacement/37-ELEC-Brake_Light_Switch_Replacement.htm
Long story short, one day noticed water in the drivers footwell, found a leak on the door to body wire harness. Dried car out. Car was 100% before this, seemed to be OK even when wet. 2 Weeks later, car started getting random faults on the MFI (Brake, ABS, PSM, etc). Would clear, then come, then clear. Battery is about 7 months old (replaced when I first got these errors) Ton of errors in durametric, then one day would not start or move out of if it did start. Peeled carpet back. Found 3 wires. 1 Crimped, 2 soldered. 1 of the soldered was gone, so cut that out, butt soldered and then repeated for the other 2 as I heard they usually go bad. Cleared all the DTCs with durametric, car started fine, all looked good in happyville. 2 weeks later got a check engine light, read codes, p0119, p0117 and p1552 (from memory, may be wrong). Seemed to be the engine temp sensor. Thought maybe a fluke, reset and ignored. This has been on and off last few months. I also noticed when hooking the durametric, or other code readers, it seemed to create a draw on the system, and the engine would idle rough, or the e throttle would not respond if I tried to drive with it plugged in. Pulled the durametric and all was fine, same with a bluetooth ODBII module I have. I replaced relay 433 under the driver's seat, and this seemed to cure that problem, since it provides relayed power to the CANBUS. About 3 months later got a PSM failure, at 45MPH and car went into limp mode. Restarted car, error was gone. Seemed fine for another month, got the same PSM failure yesterday, car seemed to be lurching a bit in slow moving traffic when it came up. Could the bad temp sensor be triggering this? It has slowly gotten worse I assume as once in awhile I see my gauge stops working. Or did I miss something else with my wire repairs. I am at the point ready to rip out passenger wiring under the carpet and inspect, but I suppose I should just replaced the impossible to reach temp sensor first, as it really does seem bad at this point. I also notice all the fuse block fuses for the PSM are on the right hand side, makes me wonder if the wiring issue is there. Just seems weird I have all these problems at once.
touareg replied to motivation's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Did you ever fix this? I am tracing down some problems too. I found 3 corroded wires in the drivers side, also replaced the relay under the drivers seat. While improved, did not fix all my problems. Looking to do the passenger side next I suppose.
touareg replied to Ddavidoff's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Not sure how things are done in Canada, but here in the past I have contacted PCNA and they have sometimes helped out. The other thing is how well do you know the Service Manager, if you go there a lot, they help you out, if you are there once in a while, they could care less. I know I got PCNA to kick in 3,000 dollars for a major repair well out of warranty, and only because I was a good customer over the years going there for oil changes, etc.
If someone wants to give me the $236 for new maps, I will apply the updates by hand and get the final answer :) Then will need to go to the dealer to get the PCM code applied so the maps discs can be installed.
I guess I am able to answer my own question, I popped the PCM 3.0 CD I have that says v2.20 on it and this is what it tells me, that I need to install new maps after the update. Next screen asked if I wanted to install version v2.20 I also have discs all the way up to v2.25. I of course clicked no as the license is not applied to my PCM for the newer maps discs. Will have to wait and see if it applies, but so far I am doubting that 1.47 is the latest version for the cayenne....
I would say your dealer, like most, learned one thing years ago and never bothers to learn more. The photo below shows v2.x as proof. I too called 4 dealers in my area and all told me I can't upgrade firmware myself, I have to bring the car in and I can only get it with a map update. This is talking to SAs of course, keep in mind an SA is like calling customer support, but they are not usually technical, they escalate, but I bet don't want to for whatever reason. I have done the 1.x to latest 1.x myself. And like all firmware upgrades there is risk. Mine updated several modules, and if one of the modules fails, you are probably SOL, as the dealer does not have the tools to do a virgin bench flash. In this regard, you are better off having the dealer do it, because if they mess up, they pay to fix it. A failed module is something only the factory or 3rd party people with the know how, can re-flash outside of the car on a bench. One tip, if your radio is pretty old, carefully use some compressed air across the disc slot, to blow off any dust on the optical lense. I never use my drive and have no idea how much dust could be on the lense, that can fubar you. The disc does show the files have CRC checks, but that is not a tamper check, just tells the system if the file looks good. Someone could easily modify a config, or change files and re-generate the CRC, leaving you in a state with a bad flash if you download a ISO off the internet. So this still leaves me the question, can I go to version 2.20 and still use my old maps, or has the code changed enough, it can't use the old map data format.
touareg posted a topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)I have a PCM 3.0 with the last v1.44 firmware for that platform. Maps are most likely from 2008/2009. There are some new features in the v2.25 firmware I would like, but I don't care to spend $350 on the newer maps (live in the city, nothing changes). I have the v2.xx firmware discs to upgrade, but I am not clear if they are like the old PCM 2.1 I had that when you went to the latest firmware, it required new maps. Can anyone say for sure (not speculate) that going to 2.25 firmware requires new maps? Thank you. The following additional functions can be used on PCM3.0 after updating the system software to system version V2.2, depending on vehicle equipment. Navigation: – Adaptation of map display according to personal requirements (e.g. 3D map setting/display and hide traffic messages, etc.) and display of these features as a symbol on the map. Selection of these features by selecting a symbol on the screen. – When displaying the list of cities containing cities with identical names, the “Details” button can be used to show an additional map with more information. This makes it easier to select the destination you want. – Additional display of set route options (toll, highway, etc.) as symbols in the Navigation main menu. – When the detour query function is activated, a traffic message is displayed (approx. 10 minutes before reaching a traffic jam). You can then choose to “Detour”/”Ignore” the traffic jam or request further “Details”. Bluetooth – The internal telephone (only for telephone module [I-no. 661]) switches automatically to Handsfree Profile (HFP) mode if the mobile phone does not support the SIM Access Profile (similar to SIM card inserted in PCM). Vehicle does not have to be re-coded in the workshop. – Synchronization of call lists on mobile phone/PCM. Voice control (I-no. 671): – Increased recognition rate due to additional street queries. A “Best Match” is thus shown and alternatives are ruled out immediately. Sport Chrono (I-no. 639/640): – Graphic display of the recorded route – Full-text search for Standard audio USB media (searches the entire database for any text) interface (I-no. 870): – New music search, starting from the track that is currently playing.
touareg replied to mjansari's topic in 997-2 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S, Carrera GTS, 911 Speedster)On a side note, can you go to v2.24 without the newer maps from 1.4 as is? Just looking for bug fixes, could care less about new maps.
