  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

  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. Hi guys, I bought my 1999 Porsche 911 C4 Tiptronic back in January and I've been doing little projects on it ever since. I used to have a 2016 Dodge Challenger R/T Scat Pack with a 6.4 liter V8 that I traded in last summer, but I was missing the sports car feeling too much so decided to buy the Porsche. One of the things that stood out to me on the test drive was just how sluggish and unresponsive the Tiptronic gearbox felt compared to the one I had in the Dodge. Since the rest of the car was in very good condition (invoices for every oil change & repair going back to 2003, IMS

  18. 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.

  19. 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.

  21. Well, I suffered 'while you're in there' syndrome... I discovered that all of my cooling system hoses, couplings, and tubes were rusted so I removed them but in doing so I decided to remove practically everything except the steering unit. This is the price you pay for enjoying drifting in the snow! It was worth it! I then discovered Dry Ice Blasting so all of the re-usable components were blasted clean. Next, I painted everything with a under body paint. (masked off all of the mating surfaces). The bearing pressed in easily as I heated the wheel housing to 100C and fr

  26. I am a "professional" that has run his own shop for many years, and my lawyer was advising me as a business owner, based upon multiple legal actions brought against similar businesses, and it two cases, individuals who did it for former buddies that later sued them for damages, and won big $. The potential consequences simply are not worth the risk. And no one here is offering legal advice, only our experience.........

  28. While the vehicle may contain VW parts, some of them are running Porsche software, which the VCDS cannot even see. Sometimes these modules drop offline when there is a water short, assuming it is not totally dead, the PIWIS should be able to see and communicate with the module, bringing it back online so it can be calibrated. If the PIWIS cannot communicate, you will need a new module, which will need to be coded to the vehicle, which the PIWIS can also do. Just remember, the 911 and Boxster vehicles also carry VW components, but the VCDS is useless with them.

  34. Porsche stopped publishing their service manuals around 2004 and switched to an online subscription service for those without a PIWIS unit (it is included with the PIWIS), so there are no reliable sources for legitimate PDF files. Part numbers you can get online from sources like board sponsors Sunset Porsche’s parts website. The Durametric system is hands down the best aftermarket diagnostic tool for Porsche.

  36. I got a PM where someone asked the dimensions of my tool, here it is. Print the image and give it to a person who can drill the tool out of nylon or something similar (strong but softer than metal). First check my image and then when fabricating the tool, make sure that the - first dimension is <105mm - second dimension is >85mm - third dimension is >43mm - first depth is 13mm - second depth is at least 13mm + 6mm You also have to drill a hole for the pin, paint pin and then try to fit the tool and you'll see which place to drill.
