    1. Does this car qualify to claim under warranty even this car is 2006? No, the factory warranty was for four years, you are well beyond that, plus you are the second owner; so unless Porsche is willing to do it under "good will", I think you are out of luck. 2. Would this fall under manufacturer defect? No, what you describe is not a common type if failure. 3. Where should I complain to? I would politely approach the dealer you bought it from in a non threatening manner. If they are not willing to meet you half way, I think you are just out of luck on this one...........

    XS batteries are over priced ($260+) AGM technology batteries that trade off higher voltage (16V) for lower cranking amps and a small weight savings. They are designed for racing applications. As your charging system is geared towards around 14V, the system is not going to be happy long term. If you want to save some weight, and run a fully sealed AGM designed battery that is fully compatible with your charging system and street use, look at an Optima battery. You will probably also save some $ on the purchase price as well………….

    If Amsoil is so great, ask him why it does not have any ACEA ratings............

    You can test it while it is connected to the alternator but disconnected at the battery, but it may be a bit of a pain to get at it while it remains connected (also depends somewhat on what the ends of the multi meter test cables look like).
  5. JFP in PA
    We have installed many of these, never had one cause a problem.
  6. JFP in PA
    You need to first correctly test the cable. What you need to do is disconnect both ends of the cable and check it for resistance over its lenght, if you find any, replace the cable.
  7. JFP in PA
    Not necessarily correct, I think there is far too much “mysticism” attached to the OEM plugs; we have used every imaginable brand or type of plug on the market, and provided you select the correct heat range and a quality type and brand, all seem to work reasonably well. One of our current favorites is the Denso Iridium’s, which seem to do an excellent job, particularly in vehicles that see more than their share of abuse.

    Not really, I our world fuel pumps are a lot like light bulbs, they either work or they don't. We just watch for common factors on the vehicles we need to change them out on to see if there is any pattern to the whys and whens of how they crap out. And constant low fuel levels are a 'repeat offender".
  9. JFP in PA
    “Contradiction in terms” department, Optima is not considered a "dry cell" (such as the Odyssey battery); the Optima is an AGM design battery with more capacity than the standard flooded cell design. The Optima is not an issue here unless it load tested poorly.............
  10. JFP in PA
    When the car is in motion, and the fuel level state is very low (< 1/4 tank), the fuel can slosh about rather quickly as the car corners and crests hills or simple rises in the road. At these moments, the pump goes into cavitation before the fuel level sensor even moves, and then recovers just as quickly. If it didn't the driver would notice a loss of power due to fuel starvation. But the result is the pump over-runs, gets hot, and wears internally. Eventually this repeated behavior catches up with it and it dies prematurely.
  11. JFP in PA
    Pretty much all of them, some are worse than others, depending upon how the pump sits, the shape of the tanks, and pump locations, etc. (note the service advisor's comments in Steve's post). Running the tanks low on fuel most of the time is problematic particularly in vehicles with multiple tanks (one will always run low before the other) or strangely shaped tanks (like the four wheel drive 996 cars to get around the driveline), but also in the more normal shaped single tank cars (Boxster or 911 type). Customer's that run the car's low on fuel frequently have more pump problems than those that don't due to the pump getting too hot from lack of cooling and cavitation. And this is not just a Porsche issue, we see it on other makes as well; it is simply an unpleasant fact with "in-the-tank" fuel pumps.
  12. JFP in PA
    The problem is that these pumps are cooled by fuel around them; run the fuel level very low all the time, the pump overheats and its life is shortened. While this is common to a lot of the newer cars, because of the way the pump sits in the Porsche, it is a bit more of an issue. And, no, I have never seen anything from Porsche about this.
  13. JFP in PA
    That could be the issue, because of their lower capacity, they are often the culprit.
  14. JFP in PA
    You might want to load test the battery as well, just to be on the safe side.
  15. JFP in PA
    No, it is just a lubricant to get the tube inserted without damaging the orings; after that is just along for the ride........
  16. JFP in PA
    It could be, but you should realize that all late model Porsches have a 40-60mA parasitic draw on the battery when the engine is not running; this current keeps everything from the correct time on the clock to the radio station presets going. This is why they have the car set up to plug a battery maintainer into the lighter socket. This drain is infamous for killing the battery if the car is left sitting for more than a few days. It’s a good idea to have the alternator checked out, but if it comes back OK, could be time to invest in a good maintainer………

    Porsche does not sell one (they only sell complete alternators), but as most of the components in these units are common to VW, Merc., Audi, and even some Fords, I'd suggest making some calls. I'd start with VW, as they tend to be the cheapest. You may want to also try some alternator/starter shops in your area . Just out of curiosity, why do you feel you need a new bridge?
  18. JFP in PA
    The computer’s internal EPA “I/M Readiness Test” mandates that the car must run through several full driving cycles (cold start, warm to full temp, drive at highway speeds, cool down to cold) before any critical emissions sensors will be ready to pass the test. This is done specifically to prevent disconnecting the battery just before going for an emissions test. How many cycles vary with manufacturer and model year, some can go over 100 or more miles.

    Oh where some minds will wander................................ :eek:

    Dielectric grease is what the Porsche OEM (and severely overpriced) lubricant is, it is a type of silicone lubricant which seems to allow the tubes to seat a bit easier. We have used dielectric grease we get in toothpaste-like tubes from our local NAPA supplier for years in the shop; works fine, never had any issues. A 3 Oz tube costs a couple of bucks, lasts just about forever, and has many other uses............
  21. JFP in PA
    A lot of people use the Optima AGM battery, myself included; the Oddessy has been a bit more problematic due to low CCA output, particularly in colder weather (most of the so-called "racing bettery' manufacturers use a cobbled up cranking amp test designed to hide the battery's lower output). Some have also noted lights dimming when the audio amp kicks in, another sign of the unit's lower capacity. Optima does not suffer from any of these draw backs.
  22. JFP in PA
    Clean engine oil is fine, dielectric grease would be better.

    There is a fair amount of truth to your proposition; there is actually a methodology that claims to have identified the harmonic frequency trace of an IMS bearing going bad using an external sensor and a recording oscilloscope device. This concept was written up in a publication some time back. Unfortunately, there are flaws in this approach. The measurement technology requires some pretty sophisticated equipment (read expensive and not very portable), and it generates a fairly complicated data set that requires technical interpretation to determine the bearing is bad. Add to that the simple fact that by the time the bearing is either making bad noises, or harmonic frequency traces, it probably has already filled the engine with the typical fine metallic grit that a dying IMS creates, eliminating any chance of saving the engine without a complete tear down and rebuild. Raby’s “Guardian” system would probably have picked up the IMS decay earlier, before it had done enough damage to be detected by either sound or harmonics, and more critically before in rendered the engine in need of a total tear down…………..
  24. JFP in PA
    Did you refill the system while it was under vacuum (preferred OEM method), or pull a vacuum after filling the system at atmospheric pressure? If it was the latter, you may still have some air in the system.............

    Without a doubt, you want to talk to Jake Raby at Flat Six Innovations; Jake is probably the preeminent M96/97 engine builder and a real stickler for detail and quality. http://www.flat6innovations.com/ And be happy you bailed on the other guys, their reputation is well earned………..
