  1. I think because you have left the orange fibre optic line open.....you would need to loop the optical if leaving out the navigation unit. But also you would need to code out the navigation unit from the system or you will always have an error with the mixing unit. What was you original issues and objective? You mentioned to set the date as time manually........ Were you having an issue with the navigation maps/unit? There are update CD's available for the mapping. Sent from my SM-G965F using Tapatalk
  2. I followed the same upgrade instructions on both my Carrera and my 2006 cayenne and all working great, pm me your email address
  3. Hi Shanus, Take a read of this and check your version numbers. If you need the upgrade discs I have all the files including the last Sat Nav upgrade dvd issued by Porsche a couple of years ago. All working on both my Cayenne and Carrera with PCM 2.1 PCM_2.1_upgrade_procedure.pdf
  4. I guess that you know you can remove that insert and that allows a larger cup size to fit.....
  5. Wallowing around. I just ordered some adjustable suspension links to drop it down lower
  6. Hi Ziller, I can't answer directly your question but I have gathered some information over the past couple of years that you might find useful to allow you to check settings with Durametric tester. As the main file is larger that 2mb I will split it and attach in two further posts....... Cayenne Durametric Suspension Adjustment-1.pdf
  7. Check the wiring loom plug located on the right hand side of the vehicle (as you stand behind the vehicle) behind the bumpers I had same fault on the rear with only the two red lights lighting up when in reverse and it was the loom plug needed cleaning and re connecting. You have to remove the rear bumper/spoiler to get to it
  8. Take a jump starter with you to power up the vehicle. Then see if the ignition key is still functional, do you have the service key available? It all depends on how damaged the original key is but the little key chip inside the fob should still be ok and just needs to be close to the ignition switch.
  9. Hi, Yes I had this problem on my rear sensors and found there was a plug behind the bumper that was not good pin condition. I pulled it apart and cleaned and sprayed WD40 then re plugged and now it's working. You have to take off the rest bumper. There is also the same behind the front bumper with the plug being on the right hand side as you stand in front of the vehicle looking at it.
  10. Pull a wire out from your wirebrush and use that to poke in to the jet hole to help clear any blockage. Sent from my SM-G965F using Tapatalk
  11. @Nurbek I Thanx very much for posting this information and the video! I will try this next week to see if the second auxiliary battery will kick in by double switching the ignition on and off in quick succession. It also gave me some ideas about testing the batteries and those solenoid relays. I already purchased 2 battery isolator switches but yet to fit them, so I may look in to that while I have the batteries exposed. My solar charger is hooked up to both batteries, the only trouble is that I park in a multi story car park and face the car south side, but in the winter in the northern hemisphere the sun is never enough in this situation. It works better during the summer months as to be expected. I'm also going to text for any parasitic battery drain. When I got the car it had an immobilizer installed but I couldn't re-activate that one so had a new one installed but the guy said he couldn't find the original one so I guess that means I have two immobilizer installed and pulling power now. Thanx again for your very useful post ? EDIT: I did a bit of searching and found this useful thread on Rennlist: 2nd Battery Question - Rennlist - Porsche Discussion Forums RENNLIST.COM Cayenne 955-957 2003-2010 - 2nd Battery Question - Since both batteries equally drain at the same time can you disconnect the 2nd battery and use to start truck in the bizarre event the main one runs down? Taking in account... it reads: Porsche doesn't supply a manual to techs that explain vehicle systems. Short of going to the actual shop manuals, there is no concise explanation of how things work. Volkswagen does however provide a Self-study Program. In talking with our techs, who have been on training for both Cayenne and Touareg, the electrical systems of both vehicles are identical. The following info is taken from the "Touareg Electrical System Design And Function" portion of the "Self Study Program Course #89J303." (updated link here: http://www.volkspage.net/technik/ssp/ssp/SSP_298_d1.pdf ) In this electrical system, one battery, the starter battery, ahs the role of supplying the starter with power and, if neccessary, also the electrical consumers required for the starting procedure (start-up consumers). The second battery, the on-board power supply battery, provides the rest of the electrical consumers with power. The batteries are connected in parallel. To prevent the starter battery from becoming discharged by too many electrical consumers, the consumers are split into two categories: start-up consumers & on-board consumers. The start-up consumers and the remaining electrical consumers are supplied from the on-board power supply battery. If neccessary, these consumers can be supplied from the starter battery via the Power Supply Relay 1. Consumers that require a large amount of energy are always supplied from the starter battery. In addition, both batteries can be connected via the Second Battery Charge Relay to charge the starter battery. The actuation of the relays comes from the Vehicle Electrical Systems Control Module. It monitors the voltage of both batteries whenever the ignition is on and can thus detect when the starter battery needs recharging. Standby The system is on standby when the Vehicle Electrical System Control Module is in sleep mode. If on standby, Power Supply Relay 1 and Second Battery Charge Relay are open. Power Supply Relay 2 is closed. Starting Procedures When the ignition is turned on, the Vehicle Electrical System Control Module is activated (wake-up mode) and evaluates the state of charge of the batteries. If the voltage reading of the on-board power supply battery is below 10.5 volts, it is deemed to be discharged. The starter battery is considered discharged if the voltage reading is below 11.5 volts. There are four different conditions that can be detected before the engine is started depending on the state of charge of the batteries: -On-board power supply and starter battery both charged -On-board power supply battery discharged, starter battery charged -On-board power supply battery charged, starter battery discharged -on-board power supply battery and starter battery discharged. Over the next few pages, it describes the starting procedure for each of the four above conditions. Long story short, the Power Supply Relays 1 &2, Second Battery Charge Relay, Access/Start Control Module, and Vehicle Electrical System Control Module are constantly measuring voltage in the two batteries and are switching and transferring power as needed. Now for charging: Two-Battery System Charging Charging The on-board power supply derives its power from both batteries which are connected in parallel and protected against overload by Power Supply Relay 1. Charging of the on-board power supply battery The on-board power supply battery is charged continuously. Charging of the starter battery Charging of the starter battery is controlled by the Second Battery Charge Relay which is activated by the Vehicle Electrical System Control Module. The normal charging time is 20 minutes. After this period the Second Battery Charge Relay will open. if the starter battery voltage drops below 12.8 volts, a new charging cycle of 20 minutes maximum is started. Not sure if that answers any of your questions, but it may help in understanding how the system works. One of my customers with a dual-battery Cayenne S left his vehicle for 3 weeks while on vacation, and upon hs return, it started with no problems. I have no idea how long it would take to completely drain the system.
  12. @bigbuzuki bumping this one for your advise about the immobilizer message that I get when trying to start the car with the service key......I'm going back out to the car next week and for sure the main battery will be flat when I get there. Sent from my SM-G965F using Tapatalk
  13. Mine has the Bose and the auxiliary battery under the sub woofer. It's easy to check and only takes a fee minutes to remover the two bolts holding in the Bose sub woofer to see under it.
