    wvicary, if you look up the part numbers in PET for the right fuel pump and the fuel pressure regulator, there is a model listed as with axuillary heater and without auxillary heater and has the labeling I7VE option for the ones that have the auxillary heater. For instance 95562084110 is the model number for fuel pressure regulator without auxillary heater and part number 95562084130 is the fuel pressure regulator with auxillary heater. What I am trying to find out is what is the auxillary heater option?

    Is anyone familiar with the I7VE option on the cayenne which involves the right fuel pump and the fuel pressure regulator with the auxiliary heater component. On my 04 CTT, I checked my VIN in the PET which does not list this option as being on my vehicle but I wanted to find out if anyone has this option or this an European thing. Is it possible to replace the right fuel pump and fuel pressure regulator with the auxiliary heater instead of the ones without the heater to upgrade or does this option not really necessary unless you are in a really cold environment.

    After fixing one of my fuel filter connections, I will get the line pressure to hold around 1 bar for around 10 minutes when off. I have not changed out the updated angled connecter yet and my filter is about 6 months old as I have been told there is a check valve in it. The car pulling timing has improved with my evom tune but is my holding pressure ok or should I be looking for another source of pressure problems given the data above states it should hold around 3 bar when off. I did check both fuel pumps which run above 4 bar each when running.

    So I went ahead and reinspected the fuel filter connections and played with the loose connection from the left fuel pump, closed up and now the fuel pressure will hold around 1 bar for at least 10 minutes now and the car runs dramatically better with just a few hiccups. I still have the angled connector but did not install it to the line from the right pump. What problems does the ooriginal connection lead to why the angled one was develped. Can it decrease fuel pressure and flow and maybe still another small issue for me. My fuel filter was replaced last year prophylactically when first trying to diagnose my timing issues bein pulled

    If one of the hoses from the fuel pumps to the fuel filter had fallen off, would the vehicle still drive or what would I expect to see. When I isolate each pump, it idles and revs ok so I would assume it is connected fine unless the fuel pump has a bypass to still get fuel to the regulator since there seems to be connections between the fuel pumps themselves per the diagrams.
  6. mbagge01
    On my 04 cayenne TT, I finally checked the fuel pressure and noted that each fuel pump holds above 4 bar which is what should be expected but when I turn the engine off, the pressure slowly drops to just under 1 bar in less than a minute. According to what I have read, it should hold at least 3 bar for about an hour. According to other posts, this brings up the question of either my fuel pressure regulator being bad or the fuel filter with its check valve. I will mention that I changed out my fuel filter a couple months ago and one of the connections from a fuel pump did not snap on firmly so I ended up zip tieing it up to hold it. Could this be my issue if I have a slightly bad connection at the fuel filter. I have no CEL codes and idle is fine but my issue really is with acceleration which leads to some hesitation and I notice timing being pulled at WOT. Recording with durametric, I found that the injection times were significantly high which I have been told is a fuel pressure issue. Even though my pumps seem to be putting out over 4 bar at idle, when the car is under WOT or accelerating can a bad connection at the fuel filter cause pressure issues. Isn't that what the regulator on the other side is doing. Is there a way to tell between a fuel pressure regulator and fuel filter issue in these cars? Thanks.

    When I replaced my fuel filter, I had that angled connector but I never used it. Also one of the connections from the fuel pumps would not click on. I believe that the inner snapping piece of the connector was not working properly but I slid it on and zip tied it up to hold it firm. Is it possible that I could have some fuel pressure issues if the connector is not secure. My idle is fine but I get some issues on occasion with hesitation on acceleration or WOT. No CEL codes with durametric. I am going to check the fuel pressure this weekend, and wondering if I would notice something with a bad fuel filter connection.

    Does anyone have the technical service group information for the angled fuel pipe listed below. I looked throughout the wiebsite and in the TSB available and it is not listed. I am trying to figure out which connection that this goes to. 955 620 911 00 angled pipe see technical information service group 2 KD-NR.2066 13/10

    in regards to the mention of harsh shifting in the early cayenne turbos that was fixed with a tcu reprogramming, is there anyway to find out if my 04 CTT has had its TCU reprogrammed, such as with duramatric?
  10. mbagge01
    voodoocat, I think that you are talking about the camshaft sensor, not the crankshaft sensor if I understand you correctly.
  11. mbagge01
    So, I am finally getting closer to my issue of my 04 cayenne turbo pulling timing at WOT with my evom tune. I ran some logs and had evom look at them and they noticed that my injection timing is way too high and is going up into 25-30ms. They said that it should not exceed 16ms and they feel that my injector timing is going up so high because my injectors are working at 100% to make up for a low fuel pressure at WOT. My question to everyone would be how would you recommend checking this problem. I have changed my fuel filter but my pumps and injectors are stock at 61,000 miles. I have not had issues at idle or mild to moderate driving and no CEL codes. I would assume that the issue would have to be the fuel pumps then but I am surprised that with both fuel pumps going at WOT, pressure should not be an issue. If it is, how do you test the fuel pumps at full capacity to check pressure. Thanks. Martin

    The crankshaft position sensor in a cayenne turbo is actually pretty easy to change. If you get up under the car, you will find it attached to the bell housing on the drivers side on its inferior side. The exhaust pipe runs nearby. You will see its wire run straight up and its connection is located right behind the SAI on the drivers side.

    On my 04 cayenne turbo, I put leistung secondary bypass pipes on and everything was going well for past six months but now the drivers side pipe will intermittenly rattle on the frame below. It is attached to all the stock hangers and I was wondering if anyone has experience on how I can perform some adjustments with the pipe so it is not rattling on the subframe anymore.

    I just replaced my n75 valve on my 04 cayenne turbo because I wanted to see if this was causing some of the surging I had noted with WOT. Again my car has an evom tune and diverters. The new n75 valve I put in has smaller hose connnectors than the one that came out of the car and I was wondering if they changed the valve design or did I put the wrong one in. The part numbers matched up. Even if the N75 valve was not working properly or I had a leak in the line due to the larger hoses being connected to the smaller plastic ends on the valve, causing an overboost situation, I would assume that the vehicle would throw an overboost code?
  15. mbagge01
    Which values should I record under durametric?
  16. mbagge01
    thanks for the help loren. Changing the sensor was pretty easy and fixed the problem. Still having the car pulling timing under WOT and getting frustrated on what to look for next or maybe my tune with evom is an issue.
  17. mbagge01
    As an update, I just replaced my crankshaft sensor and that definitely fixed my check engine problems and even improved the acceleration but the car will still pull timing and I am not sure if it is an EVOM tune issue or again something else I need to look for. I still get random DME electrical codes like the 905 one and am curious if anyone with an evom tune have had dme issues that affect performance. I am now starting to consider trying someone elses tune. I also have 2 step colder NGK plugs which I read was recommended if going around 600 horsepower but I am curious what issues could arise by going with too cold of a plug.
  18. mbagge01
    Would anyone be able to tell me where to look for the crankshaft sensor on a 955 cayenne turbo. I looked around the bell housing and found a sensor that looks like it on the undersurface on the drivers side and actually quite easy to get to but I wanted to make sure that there are not other sensors that are around there as well. I only need to find out where to other end goes for the connector. I have a picture of it but don't know how I can upload it to the site to look at.
  19. mbagge01
    I pulled the codes and now the check engine light came on with the crankshaft error and some misfire codes. I think I am going to just bring it in to Porsche and have them replace the part.

    I am also on rs6.com. I have a ctt but have done the upgrades like intercoolers, diverters etc and wonder if eurocharged have custom tunes for these upgrades on a ctt.
  21. mbagge01
    Could a bad crankshaft sensor cause problems with acceleration and pulling timing.
  22. mbagge01
    It is p0335 which durametric says is the crankshaft position sensor A. Is this accessible from under the vehicle to change out?
  23. mbagge01
    Has anyone tried both the eurocharged tune and EVOM tune on a cayenne TT. I have the eurocharged tune on my audi rs6 and love it but have been having so many problems with my cayenne EVOM tune.
  24. mbagge01
    I was wondering if there are any DIY or if anyone has experience with replacing a crankshaft sensor (engine speed sensor) on a 955 turbo cayenne. My car is starting to display weird issues with it suddenly shutting off when idling and I have had the code come up. I just recently was accelerating hard and had the CEL come up flashing but it went away after about a minute. I am going to pull the codes to find out what that was about. I wanted to know if changing this sensor can be done by myself or do I need to take it to a shop. Also is there just one crankshaft sensor or two, because when it came up as a code it was listed as sensor A. Thanks.

    I just ran the throttle body adaptation in durametric and one thing that doesn't match up is the instructions when running it says that the values will change from 3 to 14 in the bottom box and when that happens, the adaptation is done. Mine stops at 11 and it says in the last box that adaptation ok. Is there a problem with my throttle body or if durametric says its ok, the adaptation has occurred. I am confused by the software telling me that 14 should be the value that it changes to when mine seems to stop at 11.. Martin
