    Great writeup! I have experienced a generator/alternator failure. The first sign of a problem was about 10K miles ago with the car having an occasional dead battery, perhaps once every 1000 miles. The gen/alt always checked out OK. The problem was remedied by using a trickle charger. Now the unit is in total failure. How do I determine if only the circuit control needs replacing or the entire generator/alternator? 2001 996TT manual

    What I understood from a Porsche technician is that the problem seems to be loosening of the bolts that secure the gear on the shaft. Whether this was from improper factory torque settings during assembly, inappropriate strength bolts, or a design flaw of some sort is unclear. The failures are relatively rare but disasterous for the few that have it.

    Great info! Here's a link to the website: http://www.solisto.de/index.php?page=home〈=en Did you order from the website and have them ship it from overseas or is there a US distributor?

    Try driving it with your stock wheels and see how it behaves. If the problem goes away, then the new wheel width or offset is an issue. If the problem persists, then the spring rate is not a good match for your shocks (whether the shocks are worn or not is another question). GL. Let us know what you find.

    Loren, feel free to move this post to whichever subforum you feel would generate the most feedback. Thanks, Chris.

    Thanks Loren. I'll try the phone prep connector. I have an exhaust that has muffler bypass valves that are controlled by vacuum actuators, activated by a solenoid mounted in the engine bay. Originally I sourced power from a constant source in the engine bay and placed the switch in the glovebox which closes the circuit. I have decided that I do not want to add any more battery drain to the system than there already is. I am using a battery tender when it sits for several days, but I still think that these cars (some of them anyway) have horrible shelf life battery wise! Good thing mine is a daily driver.

    Also, a +12V ignition source in or near the engine bay would be helpful.
  8. roadsterdoc
    Where is a +12V source (that has power only when the ignition switch is on) in the rear center console? Thanks!

    I searched here, the 996, and 986 forums. I would like to use my NAV screen to display data from a sensor monitor. Has anyone tapped into the video input of the display screen? If not, is there a schematic revealing which wires are for video input? BTW, the video info is not complex, just numbers and bars:

    Before you let these guys freak you out, remember that the 996TT is very reliable even with upgrades. I do not know anyone who has not flashed their ecu. With your current exhaust troubles, these last two posts would make you think that you have made a huge mistake. You haven't. The AWE exhaust will buzz like hell (as will any exhaust) if the straps are not tight enough. Get under the car and tighten them as tight as you reasonably can (or have your tuner do it). The straps will not break. If that does not make a difference, call AWE directly and explain your problem. Actually, you should call them first. AWE is very good when it comes to customer service. Keep us posted!

    Try cleaning your MAF.

    Thanks Loren. As always, you are super helpful. I love this forum.

    What is the labor to remove and replace turbos (turbos only, stock fitment)? What is generally charged for this? I am selling my hybrids to a local 996TT owner and he wants to know the typical cost to install them. Thanks!
  14. roadsterdoc
    Sounds like a bad window regulator.
  15. roadsterdoc
    Not sure if it will cause that, but it is a lot easier and cheaper to replace the accumulator so it's not a bad plan. If that is the fix, you are done and not out too much $$ at all. Replacing the slave is a whole different matter. The slave alone costs around $350 and the tranny should be dropped to do it so $$$$+ labor.
  16. roadsterdoc
    I want to know the inducer and exducer measurements for the compressor wheels of the K16 and K24 turbochargers. If you have the turbine info, that would be great too. Thanks.
  17. roadsterdoc
    Your clutch slave cylinder is going out. The first sign is fluid overflowing from the clutch master resevoir. The p/s fluid level will drop as this happens (yes they are connected). Keep adding Pentosin to the p/s system (engine compartment) and keep the clutch master resevoir (up front) clean/dry until you can get a new slave installed. You can find a new 996TT slave for around $350.

    Was not able to write down the code, but is said something like "Air Injection system bank1 and bank2) I had a similar problem (secondary injector system) and the problem ws cured with new DVs.

    Do you mean the intercooler hoses?
  20. roadsterdoc
    My fan does not seem to be activating even after a spirited drive. It used to always cycle on after turning the engine off. It has been cooler (30-50 degrees F), but I am still surprised it doesn't come on. Is this normal in cool weather?
  21. roadsterdoc
    They work fine on the street. They do produce dust on the calipers and wheels. All brake pads do; there is no dustless pad. I've had the Mintex up front for more than a year. The dust they create is about the same as the rear wheels which have the OEM (original stock) pads.
  22. roadsterdoc
    Thanks, but isn't that kit for the intercooler hoses?
  23. roadsterdoc
    I agree 100%. I have used Samco on other vehicles. The problem is that nobody makes them for the 996TT (yet). :(
  24. roadsterdoc
    The hose replacement was simple. Remove airbox, remove C-clips and hose, reinstall. I went with Porsche coolant as recommended by the factory (could probably get away with one of the DEXCOOL products, but why chance it?). I knew air pockets had developed throughout the system. To get all the bubbles out of the system I put the rear of the car up on jackstands, topped the resevoir and left the cap off and valve open overnight. The following morning, topped up the level and ran the engine (still on jackstands) to clear any more bubbles. Then drove around for 15 minutes and topped up again. Seems to be fine now, but I'll check it everytime the engine cools down for a few more days (or weeks, knowing me). BTW, the blue coolant cap has been changed since 2001. The new one has a collar that extends below the center rubber/screen nub.
  25. roadsterdoc
    OK, I've found seven other incidents where this same hose failed on a 996TT, GT2 or GT3. Two were on the same car, and two were on low mileage cars.
