  1. Loren, Cleared the codes. After 1/2 driving, none have returned. I believe P0410 and P1411 may be residual codes. A few months ago, when the check engine light came on, these codes appeared. At the suggestion of a forum member, I checked the engine compartment fan fuse. It needed replacing. After I replaced the fuse the check engine light went off. I never went in and cleared the codes. So my thought is that the codes have been sitting in the engine module since the prior incident and had nothing to do with the rough idling. Does this make sense? Thank you for all your help and best regards, Maryland
  2. Loren, Cleaned throttle body and MAF sensor. Car is idling like normal, at 800 or a little less. Tomorrow, I will have the codes clear and see if P0507 and P1128 stay cleared. Regards, Maryland
  3. I have a 2000 996 Cab4. Bought it 5 years ago. I enjoy it to no end, but it does seem to continually have issues. Last month, I replaced a/c heater control and the rear window regulator/motor. I changed the oil last Sunday. Ended up putting 9 quarts of oil in after warming up the engine. I did not drive it much until the following Friday. The engine started idling rough. When i stop at a traffic light, the idle starts at the normal 800 rpms and then edges up to about 1400 rpms. If I blip the accelerator, the idle returns to 800 rpms. After about 30 minutes total driving with this condition, the check engine light came on. I read the following codes- P0507, P1128, P1411, and P0410. I don't know if the oil change is related to the codes. Reading the forums it sounds like P0507 might be caused by oil separator leaking. P1411 and P0410 have come up before. Last time, based upon forum advice, replacing the fuse for the engine compartment fan did the trick. Anyway, my thoughts on a plan of attack is to: 1. Remove and clean the throttle body. See if that clears the codes. 2. Replace O2 sensors for bank 1. Is that the left or right side? See if that clears the codes. 3. Take it to a shop to check for vacuum leaks. Does this make sense or are there other suggestions? Many thanks, Maryland
  4. On a related topic, I replaced the central locking module under the driver's seat in my 2000 Cab4. I did not have the key codes to enter into locking system so I can only open the doors manually. Is there anyway to discover the key codes? Dealer did not know of a way. Thanks, Maryland
  5. Thanks for all the help. With your advice and photos, I was able to replace the rear window regulator on my 2000 Cab 4 in a day. I found the access to nut number 9. Pull pack the carpet on the seat. There is a wiring harness plug where the seat meets the wall. Pull out the plug and you can access the nut. I needed to use a 2 x 4 as the spacing block to get the old regulator out easily.
  6. Thanks everybody for your information on this, I am about to replace the rear right regulator on my 2000 Cab 4. In step 4 of Loren's instruction on removing the regulator it says "Release adjusting elements with the adjustment tool -7-." What is the "adjustment tool"? Thanks, Jim
  7. Loren, Just saw your post. Thank you, outstanding! I don't know why I can never find this stuff in my Porsche Technical manual. Best regards, Jim
  8. I found it! What you are seeing in my picture is the roll bars that automatically deploy in a cabriolet when the car rolls over. I can see the relay behind the roll bars. I can't see the fuse but assume it is there. I am not sure how I will get to it. I don't want to remove the roll bars. I will look tomorrow when I have some light. Many thanks, Jim
  9. Rear Panel Removed copy.pdfThank you for quick response. This is what I see when I remove the back panel. What should I do next? Best regards, Jim
  10. I have a 2000 Cab4. My check engine light shows codes P0410 and P1411. I am trying to access the rear relay to check the fuse. I removed the panel behind the rear seats. Did not see a relay panel. Is it under the carpet on the driver's side back seat? Many thanks, Jim
