    Changing out the voltage regulator has been written up a couple of times, it is a simple DIY project. The regulator is inside the back of the alternator. In the US, most auto parts stores will also happily test the alternator out of the car for free as well. For a system in good shape, we typically look for idle voltages of 14V or slightly higher. When the regulator or diodes fade, we usually see voltages in the mid 13's or lower, which is starting to get weak when you consider that there is no real current draw (head lights, stereo system, etc.) on the alternator during the test. Often, just switching on a couple of these systems will pull the voltage down further, which is not good.

    Most likely a bad casting, or something possibly kicked up and hit it. You can find an exploded view of it in Porsche's PET, along with all the associated parts. I would also suggest locking down the engine as if doing the IMS bearing, and adding the LN oil pump drive for the reason stated. Not a difficult DIY, but it is going to take some time, effort, and specific fixtures (to lock the cams) to do it. The price I used was from Loren's latest list, but if you can get for less at Sonnen, by all means do so. I would also look carefully at the oil pump, they sometimes show some wear depending upon miles, etc.; so this would be an excellent time to update the oil and water pumps, as well as the thermostat while you are in there.

    Looks like #996 107 012 58, recently updated to 996 107 012 60 which is the main housing casting for both the oil and water pumps. If it is, this is going to be a fun job to replace............... And it goes for about $465.

    Tis the season for batteries to start crapping out. Have the battery fully charged and load test it, also check the specific gravity of the electrolyte. Most auto parts stores will do the load test for free if you lack the necessary equipment.

    First of all, your car should have a “normal” parasitic draw of 40-60 mA with everything off and the key out of the ignition (a common testing mistake), and you are obviously way over that. That said, you should also note that some systems stay active for a short period after the car is first switched off, so you sometimes need to let it sit for a short period before testing. Try letting the car sit for a bit, key out, and try the current draw test (ammeter between the disconnected + battery cable). I am also circumspect about the alternator voltage, 13.8V seems a bit low. Could just be a voltage regulator on the way out, but could also be corrosion on the battery cable ends, an easy DIY fix. You may want to have both the battery load tested and the alternator tested (in the US, most auto parts stores will do this for free). If the voltage regulator is going bad, you can buy a replacement from any VW or Mercedes dealership; they use the same part number and are much cheaper than Porsche for the same part.

    If memory serves, ther was a TSB on the 996 for ground wire corrosion issues, you might want to start there as a bad ground will make the car hard to start when hot and reduce the battery charge as well. The ground cables can be tested for resistance with a multimeter.

    The article has merit as the plastic impeller blades in the pumps tend to degrade and break up over time, spreading plastic bits into the cooling system that create local hot spots long before the pump itself starts to crap out.

    Interesting comment, I've never seen a multimeter that did not do DC; we currently have four different brands (and price point) meters in the shop, they all do DC.........

    The P0455 code is for a problem with the tank pressure sensor measurment, usually a classic "bad or missing" gas cap code. I could also be other EVAP ventilation system lines leaking, but I would get rid of the aftermarket cap first......
  10. JFP in PA
    If the 0301 code was the only one, it will go out by itself with enough driving. You could also take it to one of the auto parts stores advertising free use of a scanner and clear it as well.

    Glad to be of help................

    When the AOS fails, the vacuum level jumps from around 5 inches of water at the oil fill cap at idle to over 20 inches. If you do not have the equipement to check this, and the cap is very difficult to nearly impossible to get off at an idle, you need an AOS. The fact that you are also seeing smoke is a second indication. Do the AOS and be done with it before it totally craps out and strands you, or worse..............

    Simple Green has a published pH of 9.5-10, hardly "pH balanced".............
  14. JFP in PA
    While Loren is spot on about the codes, I can say that we have not found an aftermarket gas cap that works as well as the OEM units. Eventually, the Stants and other major brands tend to start throwing codes associated with vacuum leaks in the fuel vapor recovery system. We had several customers replace the OEM caps with aftermarket locking units, all of which eventually started to throw codes. Putting on an new OEM unit fixed the problem. Get the codes read and report back, if it is one of the codes associated with a gas cap leak, getting the OEM unit is a cheap, easy, and near permanent fix.............
  15. JFP in PA
    You have to be very careful about the pH of the wheel cleaners you use as they can really tear up the clear coat on the wheels if you use the wrong thing. P21S has a long standing reputation for both cleaning the wheels and not damaging the clear coat.

    "...and he said the discs were copies of the original Porsche ones" seems to sum it all up.....................

    We do not use anything but the OEM pumps; the aftermarket units have proven to be too unreliable. Sunset should be able to set you up with a good deal on the OEM unit, ask for Jeff in parts. The lot temp thermostat is a great upgrade to do at the same time, we have use the LN Engineering version with great results.

    First, let me say that listening to sound clips has proven to be the least useful way to diagnose these problems. With both the quality and volume all over the place, it becomes very hard to discern any useful information. We have had customers email us sound clips, only to find something completely different from our analysis of the sound clip when the car arrived at the shop. The best way to check out what is making the noise is to pull the cover behind the seats and remove the serpentine belt, then rotate each component looking for noise, wobble, or other signs of distress. Quite often, if the water pump is on the way out, you will find evidence of a slight leak from the vent hole under the pump as well.

    Anytime; you will find that this stuff is an excellent general purpose "squeak stopper". We always keep a couple cans around the shop.
  20. JFP in PA
    A better suggestion: DuPont spray dry teflon coating: Cost about $8 a can, sold by everyone from Amazon to Lowes. Leaves a true Teflon coating that does not attract dirt and does not bother plastic parts. We even use this stuff on sticky starter Bendix drives, works like a charm.

    tool

    JFP in PA replied to coleta's topic in Workshop Tools

    It is the Snap-On tool, well made and very durable, if a bit pricey (and what isn't from Snap-On):

    Most of the main harness is a single unit, meaning you cannot buy just one section of it. If the wire insulation is intact, you could just rewrap the harness with electrical tape. If the wire insulation itself is gone, you may have to do some splicing with new wire to correct this.
  23. JFP in PA
    Yes, it will work. As long as the Airlift unit is above the fluid level in the tank, there is no danger of it pulling out coolant.

    P1576 is a cruise control fault code, I somehow doubt that stopped your car. Are you sure you have the correct code number?
  25. JFP in PA
    Possible ignition switch, common problem.
