  1. Past hour
  2. The recommended way of filling these cars with coolant is under vacuum, it is the way the dealer and any well equipped shop would do it specifically because of these issues. I would suggest shortcutting all the top off and run it folderol and take it to someone with a Uview vacuum filling system; once connected, it will all be over in about 5 min.
  3. Tried refilling again with the burp valve up (with distilled water for now). Still overheating after about 2 miles. The needle sorts of climbs slowly then gets jumpy and goes to the right. Looks like the tank could use more coolant. If I try to remove the cap, steam comes out and then the coolant level rises back up on its own and will overflow if I don’t replace the cap. So unable to put more coolant in. Now that the car has cooled down, I went out to Discover the tank was low and I could remove the cap and it stayed low. So I topped it off again. Do I need to just keep repeating this procedure of warming the car ip and letting it cool and refilling? The videos and writeups I have read about filling the coolant don’t really mention this problem. They make it seem like you can fill it up and drive normally (without overheating) and just keep topping it off over a few days.

  5. I bought a 1999 Boxster with 17,000 miles on it several years back. The engine sounded perfect until the first oil change. After that I started getting a tappet noise which DOVE ME CRAZY! The local Porsche dealer did the oil change. I brought it to another garage that specializes in Porsches and they ran lifter cleaner through it which did not help. The problem was this: when the engine was cold it was quiet but after I drive it for a while I could hear tappet noise with the top up, or when I was at an idle with the top down. When I revved the car the noise would go away for a short while. Finally, after this problem drove me crazy for three years I added Lucas synthetic oil stabilizer. If you are old enough to remember STP additive it appears similar to that, basically a really thick additive. I started the car after the oil change when Lucas was added and the lifter noise was gone. I stored the car last year and when I picked it up this year and since then, no lifter noise. Okay, maybe a couple of tappets are noisy for a second after starting but then quiet. I use 0-40 Mobile One synthetic. My guess it an increase in viscosity is allowing the lifters to operate like they are supposed to. I would guess that you can use any additive that increases viscosity as long as it is a synthetic additive. Looking back it makes sense. The old owner probably put an additive in the oil to quiet the lifters. When I had the oil changed it had stock oil and the lifters were noisy. When the car was warm the oil wasn't thick enough to make the lifters operate properly so they were noisy.. Also when I revved the engine the oil pressure would increase quieting the lifters. I would guess that a thicker oil may make it harder to keep oil in the IMS bearing? So use any oil additive at your own risk.
  6. I followed the same upgrade instructions on both my Carrera and my 2006 cayenne and all working great, pm me your email address
  7. I notice that TSB doesn’t mention Cayenne - so is it still valid for me?
  8. Ok so it would seem I need an upgrade! angusc - would you be able to help me with the upgrade files ? Thank in advance
  9. Correct, it is warm water returning from the radiators.
  10. I guess that could explain why that hose going “out” of the thermostat doesnt feel hot.
  11. Let's just say it is not the most common approach, but it does work well when everything is up to snuff.
  12. So cooled return fluid goes into the thermostat? Is that the opposite of most vehicles?
  13. According to Porsche's parts system, you should be a 996-618-605-00 (2001, 2.7L, manual trans). The ME7.2 is the firmware inside the box.
  14. Looking at the ECU I can not see ME 7.2 or any other version written. So far I found that there is a choice of two (ECU numbers) 99661860500 or 99661860400. Will try to call Porsche tomorrow to see if they can help me but somehow I doubt it. Wondering if someone has access to such a system and possibly could check for me 🙂
  15. Hi Shanus, Take a read of this and check your version numbers. If you need the upgrade discs I have all the files including the last Sat Nav upgrade dvd issued by Porsche a couple of years ago. All working on both my Cayenne and Carrera with PCM 2.1 PCM_2.1_upgrade_procedure.pdf
  16. If it is a 2001 2.7L, it should use an ME 7.2 DME, but that DME must match the immobilizer and keys, all of which must be coded together.
  17. Welcome to RennTech The DME, immobilizer, and keys all have to match (come from a single vehicle), or be recoded by a dealer to match. The DME version also has to match the original chassis as they changed with model years. What year is the vehicle?
  18. Be careful with the Harbor Freight fuel pressure tester, it is NOT designed for the pressures your DFI runs at, which can be as high as 3,000 PSIG
  19. Had the same error code while going over mountain passes in Colorado. Anytime car had less than 3/4 fuel and 5K ft above sea level, it had really poor acceleration and bogging down. Had to keep it full to go anywhere on CO mountains. Came back to east coast and even with less than 1/4 fuel no issue with accelerating around 400 ft above sea level. I plan on picking up harbor freight fuel pressure tester kit. What else should I get to help with troubleshooting and going thru the checklist posted above? Durametric?
  20. Hello, I just bought my first Porsche as always all my cars have to be non runners so I can learn more about them 🙂 Seems like the original issue was with the alarm control unit which was badly corroded inside so seller have changed ecu, key and alarm unit but car still would not start. On closer inspection I noticed marking on the ecu and alarm control units are for a Boxster S 3.2 (with white marker). As he attempted repair few years ago original ECU, Alarm ECU and KEY has been misplaced so I have no clue which "ECU kit" I should buy of my local breakers yard as there is a choice for 2.7. I noticed that there are at least 2-3 different part numbers for each unit and also anywhere I phoned they kept asking if my remote has 2 or 3 keys which again I am unsure what was the original one. Any help would be appreciated or maybe I can find somewhere online by the chassis numbers?
  21. Thank you so much! It worked like a charm.
  22. what is a perfect condition, Mirage metallic, with stand, top worth? Bill Stowers 7757901024 willymakit9@gmail.com minden, nv 89423
  23. I just bought a 1999 Boxster and disconnected battery without knowing it needed a code: model 4462 serial X5023793
  24. This should help, it shows how the coolant flows in your car (red is hot out, blue cool returning):
