Dear Renntech forum, With regard to my 996C2MY99, I recently had a engine misfire code for Cylinder 5 (with irradic blinking and then steady CEL, indicating cat damage) upon cold-start and ver short drive. However, after reading/clearing the code using Durametric the car did not report anything again for a month. I did replace the oil (no traces of coolant), spark plugs (and the coils looked good) and changed the coolant lid to the latest .02 version. Car ran good for quite some time when suddenly it has steady CEL indicating secondary air injector failure (signal implausible) although I can clearly hear the sound of the air pump running for 30s or so. Deem my surprise now that suddenly the CEL comes on again and then blinks and indicating Cylinder 1 misfire. Any suggestions as what to do? Should I replace ALL the spark coils if the CEL comes on again. Interestingly, this happens after cold-start again and just after refilling gas (which it was the first time also). Best regards, Hans PS. As for changing the spark plugs: working my way by removing the rear bumper, and the exhaust system it was easy to reach all of them, just as indicated by this forum. Although the bolts on the exhaust clamps were rusted so I had to cut them of and replace with new wagon bolts. DS

Dear all, Thanks for your replies. I did follow the excellent DIY section (with additional pictures and suggestions provided) and could easily reach spark plugs 3, 5 and 6. But the others seemed nearly impossible to reach with only the wheel(s) removed....and I am pretty agile and not big. Perhaps if I could have fit myself under the car completely it would have worked. I'll give it a shot the coming weekend when I get my round-head hex key. But removing the bumper and exhaust should make it a LOT easier....so thanks for your tips and pictures for the procedure. Regards, Hans

Dear Renntech forum, I've been using this excellent forum for some DIY projects on my 996C2-MY99 and most things have worked out fine. Due to a recent CEL light diagnosis I opted to change spark plugs (and look/replace the damaged coils). Following the DIY guide it was not hard to get to the coils and inspect them (all looked good visually). However, I was only able to get to reach and change the spark plugs on CYL 3,5,6. Removing the rear wheels does not seem to be enough for me... Any hints on how to remove the rear bumber and/or the exhausts? It seems that this would allow for better access... I tried calling an Authorised Porsche Service Center but they did not want to give me any hints how they do it due to potential legal actions that could stem from their advice upon malfunction. With best regards, Hans

Thanks for your answers! Last evening I ran the car on idle for 5 min or so and it sounds like normal again (only cleared codes). Drove it for 10min or so and it feels like normal. It is about time to change oil and spark plugs so perhaps changing the coils (Cyl 5 and 6) is an intelligent thing at the same time. What is the model number (BERU brand) for a MY99? Have not been able to find it in the forum yet. I have not noticed any discoloration in the coolant nor in the oil (when I changed it last time). Perhaps it is an unrelated problem. The loss of coolant is very small over extended time. I'll look at the tubing as soon as this first problem is solved. Thanks again and best regards, Hans

Dear Renntech forum, My 996C2-MY99 has been running without problem but suddenly the Check Engine Light (CEL) came on shortly after starting the car. I could actually hear the engine sounding a little deeper and behaving a little sluggish at very low RPMs. Therefore, I was not surprised that the engine light came on a minute later. First steady on, then blinking then steady on again...all within 4 min of driving. Luckily I was in my neighbourhood so I could park and check what fault codes were generated. Using Durametric I got P1319, P1318, P0300 and P0305. When I today got the codes out (and cleared) and afterwards started the engine it now sounds like normal again. However, I did not drive nor keep it on for more than 2min... Alas I noticed that there is some small "spitting" from the exhaust and that the coolant level is little under min. Refilled about 30cl this summer to max after seeing a slight increase in the coolant temperature on a very hot day (98F) out driving. Could I have a leak perchance? If so where (Cyl5)? How much will this run for...... I was planning to change oil this weekend (perhaps find coolant in it?). Any help is good help! Regards, Hans

Thanks for the suggestions and links to previous posted questions. For my own problem it was sufficient to connect the Porsche Charge-o-mat (Tequipment no 955 044 900 17) which almost directly delivered enough power to the electrical system to engage/disengage the alarm system to allow trunk access (and to the battery). With best regards, Hanseman

Dear Prosche enthusiasts, My dilemma is that my car, a model 996 C2 from 1999, have been parked for all too long (locked and factory alarm engaged) and the battery has completely drained out. Now that I have to get it started I discovered (as many before me) that on my model the alarm has engaged the electronic locks to luggage hood and engine hood, alas there is the option to go after the emergency releases for these. I did try to connect 12V to the jumper that is supposed to release the locks, but all my car did was so sound the familliar beeps that it does when the engine has just started. After talking to some service places by phone, the best option given that I still have time, is to recharge the battery through the cigarette lighter connector. Porsche has recently released a charger that is a bit more powerful than the maintenance charger that has been around for some time. My question to you all is now, if this indeed is with your expertise the best option? Dismantling the passenger headlight (or backlight) to reach the emergency release (or go via the wheel house) seems a bit too risky in terms of damaging the paint and due to the weather also chilly. Any help is good help in this matter! Best regards, Hanseman
