  2. Hello, My 2008 C4S (60k miles and fully serviced) has been giving me an issue for the last few weeks, prior to that no related problems at all. It started a few weeks ago with an amber engine management light coming on around 2 minutes after starting the car from cold. It is fine at startup with the engine running nicely, but after arouind a couple of minutes the light comes on and the engine starts to run lumpy BUT when i give it any increase in accelerator, it becomes smooth and runs perfectly again - it just seems to be very unhappy with my foot off the accelerator and the engine at idle where it drops to around 500-600rpm and runs lumpy with the engine management light coming on. If i carry on driving and the engine gets 'up to temperature' then the idle comes back to it's regular 900rpm and it ticks over perfectly. I have my own code reader and the car was showing the following codes; P0040 - Oxygen sensors upstream of cat. conv. interchanged (Signal implausible) P0300 - Misfire summation fault (exceeds limit value) P0301 - Cylinder 1 misfiring (exceeds limit value) P0302 - Cylinder 2 misfiring (exceeds limit value) P0303 - Cylinder 2 misfiring (exceeds limit value) So, based on previous research on this issue, I changed all 6 coil packs, all 6 spark plugs and all 4 oxygen sensors (both the upstream and the downstream sensors on both sides). This has not improved the issue however, and still the engine starts fine and smooth, after it has run for a couple of mins, it audibly drops revs, becomes lumpy and engine light comes on, but if i give it some gas, it runs perfectly again and the engine light goes out. I should also mention that during this time of issue, it has also had an MOT and passed with perfect emissions. In my old fuel injection cars, they used a cold start valve, which was like a choke for fuel injection engines and gave the engine a bit of extra fuel to start and warm up - could this be something similar and the two minute period is when the cold start valve closes and suddenly the engine is starved of fuel and runs awfully until i use the accelerator to give it back more fuel? However, why only one bank of cylinders (1,2 and 3)?? I am struggling with this one and hoping someone may have had this or knows what's going on? Thanks, Steve
  3. I’m not sure what you have for roof rails but there are a lot of holes up there at the bottom of a channel that holds a lot of water. Those holes for screws are sealed with rubber thats getting old I removed my roof rails because I never use them to carry anything and put clear vinyl wrap over and I’m very happy that this is something I never have to worry about here is a picture of the bottom of the roof rails so you can see the rubber protection. I changed out my rear hood shocks two years ago and saw a rust on them that only could’ve come from the roof so it definitely leaks somehow. That’s the only way I can think of for that much water to get in.

  5. Hi guys and girls! I'm having some problem with my air suspension compersor, it won't start... The initial problem: Got the red suspension warning. The back of the car was on it's lowest setting. Foult: the air elbow connector on the brown line on the compressor had snapped. What I've done: - checked here and on Google for help (even some translated russian sites) - Removed compressor, fitted new fitting (not original, but something I had available at work, seal is fine) - compressor won't start when I turn on car. - compressor starts from external power source, and gives some air out on the spare wheel filling (brown line). But does not seem to fill the accumulators or the suspension. Now I'm stumped and would really appreciate if someone had some good ideas ideas 🙂 Is there some way to fill the accumulators from an external compressor?

  8. What do you need to replace the engine mounts? I am going through the same "maintenance" on my 06 C4S and am looking at all perishable parts.... Thanks, Jon
  9. Hello....need a code for CDR-220 Serial # 15075587 VIN WP0CA29802U625993 THANKS......
  10. First time poster and first 911 - AND I am not mechanically inclined. (I have contributed to the lot expansion at my local Porsche dealer to get this car mechanically sound over the past year!) I purchased the car with a brand new top. After several times of putting the top up and down last summer, we noticed that there were two holes starting in exact center of the roof. Took it to a trim shop recommended by Porsche dealer. It was then that we identified that the top was folding down over the latch that locks down the convertible top compartment lid (clamshell?) Trim shop replaced the top and headliner but did not fix whatever was causing the top to fold incorrectly. Now, brand new top has the start of two new holes. I was told that Porsche issued a service alert on how to fix this but local Porsche dealer doesn't seem to be aware of it. Any thoughts, insight or details of what can be done will be appreciated. Don't have to dummy it down for me...I'll just pass the info on to the trim shop or Porsche dealer to get it fixed so I can finally enjoy the car! Year: 2000 Thanks in advance for whatever you can share!
  11. Has anyone swapped the Black caliper, 4 piston 355mm rotor, to the Red caliper, 6 piston 380mm rotor ? Is the upgrade worth the effort ? I'm running 305/35-19's on the rear of a 1999 cabriolet (narrow body) … wondering if the upgrade would make a noticeable difference for daily driving ? No issues exist with the Black calipers, but more rubber (weight) spinning makes me question if more brake capability is warranted.
  12. I guess the problem could be with the microswitch which senses the key being turned to the lock position. I believe the convertible top will go up and the car will lock if the key is held in this position. It is odd that it happens randomly, and that the central locking button on the dash also won't work sometimes. I would have thought that a problem with the alarm control unit would more likely cause faults like that. Any dampness under the left hand seat (driver's side in the US)? That's where the alarm unit is located.
  13. The labor involved in just replacing the window is a bit more than replacing the whole top because in both cases the old top must be removed. Plus you can't fit a glass window that is the same size as the plastic. I would replace the top with a Gahh A-5 German canvas top (OEM). You can chose between plastic or glass(more money) for the window . I went for the plastic window because it looks more like the lines of the coupe. The glass window is significantly smaller. It's a personal choice.
  14. I emailed harveypnp@comcast.net It bounced back might anyone know where to get a oem looking set of scuff plates like he had made I would like to find a set.
  15. Hi, anybody replaced the coolant vent line (987 106 681 01) in a 987.1 2.7 boxster and has some tips? Mine has been holed by contact with the variocam cover plate (i think), red arrow in picture shows line and location of hole. Maybe i'm being pessimistic but looks like to wriggle it out/in would need to remove main coolant hoses at the front of engine, engine mount, suspension brace, possibly also rusty exhaust. I tried an in-situ fix with epoxy which failed. May also try replacing damaged section with flexible hose. Car is on jack stands. Thanks, Mark
  16. I have HAES speaker for doors and want to upgrade it. Is the oem Bose speaker better than oem HAES speaker?
  17. The fix ended up being a missing 5a fuse for the TIPTRONIC on the right fuse panel(52). My question is how was the magnetic lock working before????
  18. The battery was dead this morning and now the radio is as the car was.. I need help with the radiocode thanks. Porsche CDR-220 Type:4462 Serial:Y5053657 46/00
  19. Job is almost finished. While i was in there i pulled my battery tray and sanded it then i painted it. Rust is not good. Few questions, i noticed another blend door that was not accessible. I tried to put some tape on it. Ideas anyone? I cut off the top pivot point on the blend door i removed. What did you guys do to cover this part. I will try to finish up tomorrow and test this fix. 1999, 996.
  20. Well thats what I was thinking. Purchased a different one anyway. thanks v
  21. This little how-to helped me a lot: https://www.renntech.org/tutorials/article/19-how-to-service-the-buttons-lcd-in-a-becker-cdr-220
  22. Code worked. Donation made as a token of appreciation. Thanks again
  23. I am working thru this problem also. I have the top work done, getting ready to do the servo arm. So far so good. Checking in from south east Texas btw.
  24. Yesterday
  25. Trying to replace some vacuum hoses under the passenger side intake manifold. Is there a DIY any where? I’m taking off the driver side first. Would I need to remove the AC condenser and/or AC lines/hoses first or can I just leave them as is? And how do you remove the power steering tank? I read somewhere that it just twists off at the pipe?
