Airbag impact sensor under the carpet under the seat, looked like something spilled down there. $500 at the dealer, but I found a used one on ebay for $40 different car but same part number worked fine!

I have the same problem my Srs light is always one. It would of been nice if you posted some pictures while you did the job. I would want to replace mines too. Do you have to take out the whole seat?

Yup, the whole seat comes out I will post some pics, when I get a chance. Easy, seat all the way back remove two torx in front then power the seat forward and remove the two torx in the back then power the seat all the way back. Under the seat in front is a bunch of plugs, and a vacuume hose. Disconnect the battery for safety unplug all the connectors and vac hose, then remove the seat from the car. Under the rug is a airbag sensor can't miss it, it says airbag sensor! Remove and replace clean connector while your in there, put the seat back, reconnect the battery start the car and good to go!!!

Oh wow its sounds kind of easy except for the connection and hose disconnection part. I wouldn't want to mess anything up. Thank you for explaining the whole process to me. I also was wondering if you knew the part number for the SRS light?

Unplugging the connections is easy big black one is like and ECU type, you need to slide the plastic piece over to release the connection. There all pretty easy and the vac hose you need like a pick to pry the hose out without damaging it.
