805A Passenger's front sensor no communication - Resolved
It was my front passenger airbag sensor that failed. Using the information in this thread I was able to replace it going through the fog light opening. I had to research how that connector comes off and fiddle with it to actually get it off. It is indeed doable going this route. Start to finish was about 60-90 minutes as access is tight. If you have an electric or pneumatic socket wrench it may be easier.
Connected up my Foxwell NT-520 Pro and scanned the codes, cleared the airbag code. Turned off ignition. Restarted car and airbag light went off in about 2 sec. Attached is a few screen shots of the process from the Porsche Manual in case anyone needs to see how the connector works and torque values.
Front airbag acceleration sensor - 997-618-223-02
Purchased online from Gaudin Porsche in Las Vegas for $108.26 including shipping.
Part # 997-618-223-01 is the side impact airbag sensor
Does anyone have pics and/or tips on how to replace the sensor through the turn signal/fog lights? One said it took 60-90 min and another said it only took 10 min.
This is looking through the passenger side fog/turn signal opening. The sensor is at the top and the two nuts are circled. There is not much room to work.
@911URGE - Thanks! Super helpful. Ordered the part last night.
Make sure to disconnect the battery and wait a few minutes before doing this work - This was a note in the service manual. It can be done this route but I could never get two hands in there. I had to use painters tape to hold the new sensor in place to keep from falling off the mounting studs. Good luck and let us know how it went. You will need to clear the code as it will not reset after the replacement.
Done via foglight. My brother-in-law is way more handy than I and has more tools. So went to him and we (he) tackled it, in about 20-25 min and if had to again prob could in 10 min.
Hardest part was the clip removal. We were using the trim tool we used to pull the light out which didn't work and had us second-guessing we were going at the right spot. Once we switched to a thin/small flathead it was out instantly.
Think the key was 1/4 drive socket wrench -> 3/8 adapter, universal joint then 3/8->1/4 adapter (to add a little length) with a 10mm socket on the end. That made it reach.
