  1. The factory default for the valves is the loud position, so if they are not hooked up, that is what you get. The valves only move to the "quiet" position when activated. The original reason for the valves was the incredibly restrictive Swiss noise laws for residential neighborhoods, so when the vehicle was operating a low speeds, it was quiet.

  2. Sometimes when there is a voltage spike to the system (like connecting a new battery) the programming can get "mixed up". When this happens the best thing to do is have a tech/shop with a PIWIS re-program the affected control module(s). I think it very rare to replace a DME if most everything but one or two items are not working.

  3. All of the larger cables are susceptible to this problem. The longer the cable, like to the starter, the worse the problem because their length exacerbates the resistance issue, leading to larger voltage drops. The only real trick to checking each one with either a multimeter or Power Probe unit (Power Probes actually have a specific setting for checking voltage drops, plus the Power Probe's long leads back to the battery make the testing process easier).

  4. Porsche "Book Time" to replace both front wheel bearings is 4.7 hours times your shops hourly rate. Porsche "Book Times" are usually a high estimate - an experienced tech can usually do the job in much less. So let the shop quote time - as long as it is under the "Book Time" you are likely good.

  7. First of all, LN Engineering's IMS Solution is a LOT more than just an oil feed line; the bearing insert is a solid bearing (no moving parts) with annular oil passages just like the almighty Mezger turbo engines used, the IMS shaft is plugged to prevent oil accumulation and the balance problems associated by running the shaft full of oil, the replacement rear IMS flange is coated with a Diamond like coating for strength and longevity, and the oil feed is sourced at the oil filter to get clean, cool oil rather than where some others have sourced it. Perhaps one of the biggest advantages of the

  10. Be aware the most dealer will not share the service records for the vehicle because they legally belong to the previous owner(s), and the dealers are uninclined to track them down and get a legal release.

  11. I agree with millerchris85. After all the work and money poured into my CTT it’s eh now and I’d have been better served tuning up my 996TT. If you really must have a sporty drive in a Cayenne then I suggest looking after a 958 GTS, Turbo or Turbo S and having someone tuned them to your liking. Be forewarned though you will wear through ancillaries (brakes, axles, tensioners, etc...) much faster depending on how much and how hard you drive

  14. A couple of days ago my head unit started cycling off and on every minute or so. I found some posts that these things are notorious for failing so I started looking for a place that would repair it. Luckily I found the Becker office in Saddle Brook NJ, called them, and they emailed me instructions how to fix it. Apparently my XM SAT provider caused the problem. It required a reboot as per below: WARNING It was brought to our attention, that the PCM 3.0 and 3.1 units have been rebooting continuously on a number of Porsche vehicles at the moment. It seems that a signal was s

  15. OK, first of all, either twisting wires together and wrapping them with tape, or using wire nuts is totally unacceptable for automotive applications. Both are pathways to shorts and even fires. Wires should be reconnected with crimp connectors at a minimum, with soldering them and then using heat shrink tubing to cover the soldered joints the actual preferred method. Most likely, in the process of doing this swap, you disturbed something, but exactly what is hard to say, particularly as the previous owner used the twisted wire and tape wrap method of connecting things. It is ent

  16. Sorry for the delay, but the Virus has made things upside down everywhere around New York. Hope it's not too bad in Cleveland.:) I think I found some initial pics that can help you get started in solving the problem with your top... Here is a series of photos on my '97 Boxster when it still had the original "A Version", all metal housing transmissions. I think that if you put your clamshell manually to this exact position, and then duplicate the position of the V-levers and other parts, you will have an excellent starting point. Forgot to me

  17. You should not have to - unless you hooked up the new battery backwards. If the polarity was hooked up correctly then you need to start looking for poor grounds. Starting with the battery cable then chassis grounds.

  18. Your stated voltage measurment is weak. You should be testing the primary cables, the large ones running from the battery to the ground and starter, these are the ones that tend to develop internal corrosion. If you are unfamiliar with this test, do a search as this has been covered several times previously. We always load test both the alternator and battery when there is a problem. While this requires a load tester, it verifies that both are capable of delivering both the correct voltage and current (amps) as required.

  22. Most likely the control boxes have returned to factory settings after the work which has been carried out. Run the "Vehicle handover" program using a PIWIS tool and you should be fine.

  25. It doesn't need to be left open, simply buy a quality battery maintainer like Ctek, plug it into your cigarette lighter socket, run the cord out thru the cut out in the bottom of the driver's door (there for this exact purpose), and let the car sit for months (locked with the alarm on) without any issues.

  26. I designed a cup holder for use in a 996/986 with the ashtray delete mod. The files are available on Thingiverse (free). I also have files for the little plastic disks that cover the rear attachment points for the hardtop on a cabriolet, and seem to vanish every now and then. The cup holder is in two parts. The bottom screws into the existing holes in the ashtray delete, using the existing screws. The top part narrows the opening a bit so that a can or bottle won't move around. It's easily reversible - just remove the two screws, pull out the cup holder, replace the screws.

  27. The install is great news GSpence2, i’m sorry to hear about your O2 issues. Hopefully you’ll get them resolved soon. I did the intercooler upgrade at the same time as a tune so I couldn’t tell who the real boost hero there is. I'm guessing both because the car pegs the boost at .8 at WOT every time now which would be the tune but it holds it well thanks to those big intercoolers. Good luck and please keep us posted. Joel

  28. If you add the 997 GT3 master cylinder (27mm bore) to the 996 in order for the psm/abs to work perfectly and not throw any codes you will need to install a brake bias adjuster in line between the rear master port and the psm pump, it needs to see about 7% reduction in pressure or it will throw a psm/abs code and shut down the system. Note the 997 gt3 master has both ports 12mm bubble flair, unlike the 996 masters that use 12mm front, 10mm rear so you will have to make a custom line or a adapter (they suck) Anyway it gives you a rock hard pedal with the 997 or bigger brakes and all works as

  39. I second the comments that Maurice has been a great help. I was able to diagnose my problem to a broken tip on one of the cables that caused the red ball joint to break thus warning me there was a serious problem before I completely ruined the clamshell. As it is, I think I may be able to repair it and at worst case I have found a replacement at a salvage yard. I may still need some help on where to position the V levers since I had to take those off to release the torque. Thanks Gary

  40. Sorry, my mistake - your car is a 987. Yes it is on the drivers side but access is through the front trunk. You will need to remove the luggage compartment lining to get to the upper plug. and remover the two torx head screws. Then remove the inner wheel well lining and disconnect the canister fittings there (underneath the canister as you lift).

  41. A few points to add from a '99 Cabrio owner in Central Florida. I ran into a couple snags, and wanted to pass my info along in the hopes it'll help someone else out there, and you can plan your weekend morning accordingly. 1. Finding the Right Fluid -- Wasn't as easy as I'd hoped. I went to the two major car part store chains in my area (AutoZone and Discount/Advance Auto Parts) and didn't have any luck finding either John Deere or Pentosin fluid. Ended up going to Bennett Auto Parts (on my way to Tractor Supply, which I assumed had the John Deere) and it turned out Bennett had it and carrie

  43. 1. Pull engine cover vertically upwards and off. 2. Separate the six ignition coils from the wiring harness. Refer to the following note for more information. It is very difficult to access the ignition module plugs to unlock them. Therefore, use a suitable tool (e.g. a bent piece of wire) for unlocking. Press the plugs against the ignition module to facilitate unlocking. Otherwise, the plug locks may break. 3. Press plugs down slightly, unlock with a suitable tool (e.g. bent piece of wire) and remove. 4. Pull out ignition coil and lay it aside. 5. Remove the spark plugs. 6. Chec

  44. Here is the fix for code 0740 on Tiptronic. After refilling fluid (by the dealer the last time), the code would come back after 100 miles or so. The potential fix from Porsche was a new tansmission, around $7K. Before I spend that kind of money, did some research that lead me to the following for P0740 code: Since the fluid was changed, went to step 3. Here is the location of the pressure regulator and how to remove it. You have to drain the fluid and remove the ATF pan to get to this part, then it will be obvious. There are ATF filter change instuctions in the DIY that will help wi

  45. The Transmission manufacturer is ZF, the attache file is the recommended fluids for the 5HP19 transmissions. I changed my ATF in my 1999 Tiptronic car and used the VW Audi fluid. Its all the same Oil just repckaged for each dealer. AUDI, Porsch, BMW etc. The place where I purchased my fluid is ETY Parts in LA thier email: ETYPARTS@AOL.COM 1.877.ety-part (Toll Free) 323.254.7442 (Local) Here is the ATF link. http://catalog.etyparts.com/item.wws?sku=G...mp;clientid=ety P.S. I decided to use the factory ATF inlieu of an after market such as Penzoil because this is what ZF recommends
