Experienced the same Jamie, though on the Autobahn at significant speed, why I had the sun roof open I do not know. It fell partly off and slammed my roof, not a sound you'd like driving fast, thump thump thump thump. Amazing it did not fall completely off, just reattached it, no clue, has stayed on since.

Thank you for this, I also just installed a magnetic oil drain plug. Now I do not need to worry on the coming oil change, just the next one  :cheers:

Ahsai and jemi, I would also suggest that. I have changed a couple of sets of these, never seen the valve lifter errors though. 

Sorry to hear it, have you checked your fuses?

Just changed the spark plugs and coils on a friends 997, he could not be happier when we were done, the car ran perfectly. I did mine on my 996 last summer and they looked horrible, incredible any of them worked at all. The 997 coils were all produced in 2004, some had began to deteriorate, mine were all produced in 01 and would not last the season. If you have your original coils on your car (996) it is only a question of time as to when you have to replace them. Lastly it is a DIY, a bit fiddely, but with keyboard fingers and computer physics it should not be a problem :thumbup:. The first time it took about five hours, the second time not more than two, and if you dare to dismount the muffler it should be a jiffy. 

 

The error codes PO492 and PO491 was the ignition system, we replaced all spark plugs and coils. Deleted the error codes and started, all fixed.

How many miles you've put on the car since then? It may take some time for the P0491/P0492 codes to come back after a DME reset.

 

Hi Ahsai

We have tried various things prior to this, MAF replacement, just clearing the error codes. The error codes always reappeared after 30 seconds on idle. The engine was running rough with misfire on cylinder 1, it does not do that anymore. After one days use the car has no error codes, we must call it a successful DIY, my friend was very happy with the result.

The error codes PO492 and PO491 was the ignition system, we replaced all spark plugs and coils. Deleted the error codes and started, all fixed.

 

I just had a similar problem. Turned out it was my floormats which after being saturated with our endless Boston winter actually started stinking like an old shoe. It was brutal - and thank god solveable.  My fault for not bothering with the winter mats. This reminds me gotta by new ones. 

 

The weather here in Bergen, Norway is rainy all year round. Whenever I buy a new car, I always buy proper rubber floor mats. You would be surprised how much water you actually bring into the car with you from your shoes. The 996 do not offer original rubber floor mats, but you can use the set for the 997. I have that in my car, the inside of the car is dry, atmosphere is better and fogging is not an issue. Would strongly recommend it.

Have a friend with the same fault codes on a 05 997s. 

What happened:

My friend did a run in his car, the car was warming up, might not have had full operating temperature. Upon accelerating he hit the rev limiter and the motor started running rough. 

When we used the Durametric on it the first time it had misfires in every cylinder except number 6 and running rough. After deleting and trying again, it now only misfires on cylinder 1 and still running rough.

What we have tried

• detached the MAF
• switched with my MAF
• Deleting the fault codes with Durametric
• Checked some of the hoses in the schematics mentioned above

Error codes:

• PO492 - secondry-air system bank 2
• PO491 - secondry-air system bank 1
• PO3001 - misfiring cylinder 1
• PO3005 - misfiring cylinder 5
• PO3004 - misfiring cylinder 4
• PO3004 - misfiring cylinder 4 (two of these acctually, but not a PO3006)
• PO3002 - misfiring cylinder 2
• PO3003 - misfiring cylinder 3

Any suggestions? Did your cars run rough when having the PO491 and PO492 error codes?

I have these NGK Spark Plugs BKR6-EK also, changed from Bosch. Also did the coils, recommend everybody changing the coils every 100 000 Km.

I have quite prominent wheel hop in my 02 Carrera (140000 km), I guess my engine mounts are shot. Which should I buy to eliminate wheel hop? New OEM, semi solids, any reccomendations.

I can report that the leak is still there, a few drops each night. Can also report that the oil level displayed from the digital gauge in the dashboard has sunken a few lines from max. The dip stick shows almost full. My first report that the oil level was at max, was before the incident where I parked the car in the hill. So the oil level has not sunken further.

Based on your feedback RFM I have devised a couple of theories.

I had the car in for work in October, LN Engineering IMS, new RMS and clutch. The assembly of the car was done poorly and I got a very squeaky clutch https://www.youtube.com/watch?v=Olq6OqMzcDc. The shop fixed that under warranty.

Theory #1: The combination, thin 0w40 oil, hot weather (very unusual in Norway) and standing front down on a steep hill for a few days resulted in oil seeping through the RMS. The oil still resides in the bell housing seeping slowly out. Solution, I have to mind where I park my car, not in a steep hill facing down, maybe change to 5w50 oil, with that in mind the dripping should stop.

Theory #2: The guy at the shop who did the job also did the RMS replacement poorly or that the new RMS seal was faulty and it just simply leaks. Solution I go back to the shop and claim a warranty on the RMS.

Thank you for the comment, does that mean the RMS is gone or that it will leak each time it stand in a steep downward angle you think?

Hi
 
I have searched around for a while but I'm unable to find similar post. My 02 Carrera has a small leak dripping from the bolt indicated by the green arrow (do not get confused by the read cross and circle, used photo from web). 
 

 
Had my car standing in a steep hill facing down for a couple of days, just outside my garage. When I got it on the flat surface of my garage, it leaked a few drops of oil. The oil level is at max. 
 
I cleaned the area from underneath, placed a cup directly underneath, and no further dripping, although the area around the bolt had become a bit greasy and I could get oil on my finger. So no high level of oil loss. I have not noticed more dripping.
 
Anybody that has experienced this or know what that bolt is for?

This stripping got loose also from my car, but only half way off. We were driving quite fast on the autobahn last summer, heard a horrible sound at a speed of about 200 Kmh (120 Mph). Stopped immediately, it was only this part that had gotten loose from the sunroof hitting the top the roof.

I did this fix the other day, just as mentioned in my previous post. It worked, nothing went wrong and the car now has no air-bag warning light or any faults.

Experiences and hints to others doing the same fix:

1. Have water pipe pliers handy to get off those pesky nuts to release the trigger unit. They came surprisingly easy off by the way.
2. You do not have to remove the centre lower dash unit, but I did, easier to get to the unit. Use torx screw driver.
3. To remove the centre lower dash unit, there are four screws, two at the back of the unit and one on each side behind the side panels of the unit. Easy to pry off panels from the back of lower centre dash unit.
4. Also pry out lower centre panel with seat heater buttons, disconnect the connected wires. Those were quite difficult to disconnect and reconnect actually, short wires on my car maybe.
5. Be very careful when disconnecting the triggering unit, and especially when reconnecting. The connectors are very very small and would be very easy to break
6. Have a Durametric to check your fault codes, I was left with four fault codes, 3, 4, 26 and 28 (if I recall correctly). Erased those ones, shut of the ignition, started the car. And whahey no air-bag warning. The small light comes on when starting, but disappears after a few seconds, and no large warning shown in main display. Love it, absolutely love it, and very proud.
7. My unit fitted my car perfectly, and came pre-locked to a 996 2002 model, same make and model as my car. So no locking issues.

Got the part of ebay, a reseller with the peculiar name of stevestrange007 in England, cost me a total of about $100 including shipping, fees and VAT. The reseller had tested the unit prior [he mentioned] and the unit had some text on it indicating this was true. A small price to pay compared to the quote I got from my local Porsche workshop, they quoted me about $2500 for the job. Where the price of the unit was $1300. A total save of $2400 :cheers:

:drive:

Going forward with this fix tonight, crossing all my fingers and toes that I do not trigger any of the air bags.

Planned procedure:

1. Remove lower centre console
2. Locate the Trigering unit
3. Turn of iginition, remove key
4. Disconnect battery, wait for 15 minutes.
5. Disconnect triggering unit
6. Replace unit and connect in order, trigger unit then battery
7. Hope the finger and toe crossing worked and hopefully no aibag release
8. Connect Durametric and read fault codes
9. Erase any fault codes

Anybody got any recommendations to my plan? Anything I should do different?

Thanks for impeccable help.

I am having the same issue and have two questions.

1. is the airbag control unit the same as the mentioned triggering unit?

2. I have 2002 996 Carrera, will this item do Porsche 996 airbag control unit ecu 99661821902

3. Where is the control unit located? cannot find any information about that
