    Are you using a diagnostic scan tool that is more than just basic? I would say at this point you need to analyze the Abs data and see if anything is out of the normal. vizcarra44

    I never came across a Dme that got amaged just cause you disconnected the connectors while battery is connected, maybe with the key on. Anyhow its always a possibility. Look at the attachment, and if you do need a dme well then if you do not have a Pst2 tester and Ipas codes then you are in over your head. Of course there may be other causes for your problem but you need a good knowledge of how the engine management system works. good luck, vizcarra44

    Here's some interesting Dme Data for all of you to have. Riddle me this, why is it that it seems as if the car runs better when you disconnect the Maf and reset the dme. What is the dme doing? How would you find out if a misfire was caused by internal engine components or external engine stuff, just by looking at the dme data? vizcarra44

    Does code come back instantly on first test drive? Any driveability issues? Here is the Fault plan. vizcarra44

    I remember at the dealer we had a couple of Pourous case issues, the Factory just had us use JB WELD to seal the pore. vizcarra44

    Its most likely a coincidence. I attached the code description and fualt plan. Good Luck vizcarra44

    To do the water pump is not to bad, to get to this all you have to do is remove the carpet sound pad behind the seats and remove the ft engine shield, couple of 10mm bolts, then you have access to ft of engine and pulleys ect. I wouldnt drive this car to far before doing a complete inspection first. If your water pump goes it can cause some major problems. if you are not mechanically inclined go to a reputable shop and have them look at it. To isolate noises i would just use a very long screwdriver with the handle pressed against your ear and the tip of the tool on the suspected noise area. I have attached some labor times from Alldata for t-stat, water pump replacement. Note that if your water pump is gone I would also have the T-stat replaced as well. And make sure the shop that does the job knows how to refill the cooling system with the vacuum method. good luck, vizcarra44

    Are you doing this on the floor? Cause its so much easier on a car lift. I dont recall any special adjustments needing to be made, put you will need the right clutch alignment tool. Good luck and have fun. vizcarra44

    Maybe its the recording quality, but it sounds bad to me, check your water pump pulley to see if its moving side to side excessively. vizcarra44

    wow, I would like to show you guys how to test instead of guessing and throwing parts at the car. There can be so many possible causes, but you need a diagnostic plan and an understanding of how this engine management system truley works. I am a professional Porsche Master tech and all this advise giving on maybe its this or that is impressing. Take it to the dealer and have the shop foreman look at it. Last thing you want to do is make this car a money pit.

    I have heard that you can go to your local auto parts house (kragen, autozone, etc) and borrow their code reader if they think you'll buy needed parts from them. That will at least save the money if there are no codes. David I never had a bad Maf cause a no start, but you never know huh. With a good Obd scanner you should be able to see if there are any pending codes, that have not matured yet. Also, when your cranking the car and its not starting, usually a code will not set due to the fact that certian systems need to be within particular thresholds to have the ecu monitor systems for problems. When using a basic scanner just look at the short and long term fuel trim, anything above 8% negative or positive is a problem. There are many different diag strategies for no code problems. You just have to find a tech who likes to troubleshoot. Regards, vizcarra44

    Hello Chris, I am a former Porsche tech and I never saw a dirty t-bdy cause a check engine light, now the wandering idle yes. I would look at the dme data to see how the Rkat fuel trim looks as well as the Lambda values and Maf value. It gets expensive guessing I imagine. I am a firm believer in proper diagnosis, not just parts replacement, so when people start to tell you it might be this or that, take that advise at your own risk. Now for the air duct to come off, I just used a twist and pull at an angle step, with a little umpff. to get the clamp loose, I used to use a swivel 1/4 ratchet with i believe a 7 or 8 mm socket. regards, vizcarra44

    Sorry for my ignorance, but what does that mean exactly? It means that your coolant temperature is 215F+ when the gauge is sitting just to the right side of the "0" in 180. Factory spec is 90-95 C vizcarra44

    Greetings: I have a 2006 C2S... 2843 miles. When I first purchased the vehicle I had a hesitation issue or more like " Cugging " on 2 occasions. I was told this is most likely when the fuel is at 1/4 tank. I now always keep my tank full and have not had the problem since. I also use an octane boost once in a while, maybe every 3rd or 4th tank. Does that help, that's up to debate. However by keeping my tank on the full side I have not experienced any " Chugging " . Chromedome, North County San Diego Seems to me you have a gremlin in your car. Sometimes the dealer will not look further when they cant duplicate the situation, has to do with warranty not paying them for deep diagnosis time. any how make friends with the Shop foreman and get him involved so that maybe he starts to send some Ptec's in to porsche on your situation, I would personally hook up a scan tool with flight recording ability and graph the dme data for analysis, unfortunately the dealer scan tool does not have this ability. vizcarra44

    Just curious, why do you need or want a dme that is wrong for your car? The dealer guys Know what there doing, and if they said there waiting on you for a response-- doesnt make sense, they have factory engineers via Ptec avialable to answer any and all there questions. Maybe they are just dragging this out.

    do we have an update? First off, If your going to take it to get fixed, make sure he is a technician not just a parts changer, things can get expensive if its not diagnosed properly. The Tech should first analyze the dme data and look for the tell tale signs of rich or lean condition, for lean condition I would then procede to look for vacuum leak, oil filler cap as Chris said, and If you dont have a smoke machine, use propane around the intake, oil separator ect. and look at the o2 signals for rich reading, high voltage close to .800 1.0 volts. If no leak then most likely it is your Maf. By the way to test an O2 sensor to see if it is Biased Lean all you have to do is create a rich and lean condition and see voltage transitions, usaully with O-scope, transition time should be less than 200 milliseconds. if no transition then you have a dead o2 sensor. The tech should do a hard reset after erasing codes to reset the adaptation values back to 0.00 vizcarra44

    The alternator needs to be disconnected at the alternator itself, What can happen is the diode pack within the alternator fails (Diodes only allow current in one direction) the alternator in this failed state then draws current like an electric motor. It is a lot more technical than this explanation but this is the gist as i dont know how familiar you are with auto electrics. You will also have to trace any additional equipment added to the car Agian if you had the right tool you would be able to diagnose this problem quickly, the dvom is not the way to go. Now to isolate this draw without having to remove the alternator I would first remove the connector to the ignition switch, pin 50 is excite voltage to alternator. If draw is gone then it is your alt. If not then I would take off engine cover and right by the power steering resevior is the Terminal 30 permanent B+ disconnect that to isolate if draw is from alt or something in the engine compartment. Agian if draw is not from alternator, check your alarm module under seat, sometimes the connectors get corroded and cause a draw, also pull the fuse and check for corrosion. vizcarra44

    Would anybody be interested in how to truley interpret the Dme data such as what does the Lambda value really tell you. Example values for 996-986 dme values, understanding what TRA and RKAT's truley mean. How to find out if a misfire is caused by internal engine components or external engine items. I used to be a Porsche Dealer tech, now retired from that, but I do miss the challenge of diagnosing engine performance issues or electrical problems. I live in the L.A. South Bay Any one who needs help, just contact me. I have access to piwis tester and friends in dealer and Texa scan tool to help Porsche guys out. vizcarra44 vizcarra44@yahoo.com

    Hello guys, As I remember the tank pressure sensor is on top of the fuel tank to the drivers side, that would be right of the fuel pump. Now you gotta have small hands cause its a buger to replace. Now you might find that the wire harness going to it is chewed up by rats. This was always the case. So it might not be the sensor after all. as for the diagram, its not always truthful. Being that you say the light returns tells me its a wiring problem. vizcarra44 vizcarra44@yahoo.com

    Most likely there is too little coolant in the tank. Make sure you properly purge air from the system. It may take several fills of the tank to do so. Best way is to park the car after driving it with the nose down and the purge valve open, or drive around with the valve open. The proper way is to use the vacuum fill method, I never had a problems using this. the tool is made by UView and is called AirLift, snap-on or matco tools sells it under different name. any how a blinking light? I would first pressure test the cooling system and look for signs of leakage. To refill if you do it any other way its the wrong and long way. Any body in South Bay L.A. area need help with this, no problem, Id like to help out for free. vizcarra44 Master Tech vizcarra44@yahoo.com

Best way is to park the car after driving it with the nose down and the purge valve open, or drive around with the valve open. Wow, lots of instructions for a simple job. First off, the blinking light is most likely caused by a bad coolant bottle. As a tech I would first pressure test the cooling system, use a mechanics mirror to look at the bottom of the bottle for leaks or at least traces. flushed cooling systems, you only do this when you have some horrible problem such as oil and coolant mix. Second, to properly refill a cooling system, yes you must only use the vacuum fill method. The company who makes the tool is called UView (Air-Lift) and it is rebadged and sold by snap-on, matco tools, or online at toolsource.com Anybody in L.A. area who ever needs help with this, no problem it would be nice to make new friends.

    Please re-read the board rules and guidelines that you agreed to when you registered here. Commercial posts are not allowed nor is flaming individuals or companies. If you did not work for competing company your comments would be just "your opinion" - being that you do work for a competing company it is a flame and will not be tolerated in the future. If you believe your company makes a better tool then by all means tell us what it can do. Better yet send an evaluation to one of our staff to be reviewed and evaluated. This particular thread is intended to be a Registry of folks willing to help other (for free) with the diagnostic tool(s) that they have whether it be PST2, PIWIS, or Durametric Software. In the future if you wish to discuss a new or different tool - please start a new thread. Thank you. So I take it that you are part of the Staff. Or a senior Renntech member. I have noticed that you have written very highly of the other scan tool. Any how I am not trying to sell a scan tool to porsche aficionados. I would like to offer my help to any one in the L.A. area with any type of Diagnostics since I am a Porsche Certified Tech / A.S.E. Certified Master Tech as well. I miss troubleshooting and would just like to help for free. I dont own porsche, but I love to fix hard engine performance and electrical problems. vizcarra44 vizcarra44@yahoo.com
