Air bay control module

[Capecod 02/4S]

I’ve been trying to clear an airbag light for weeks as noted in other post. Brought to Porsche and they sent me away indicating they’d provide an estimate for repairs only to later tell me they needed to open up the driver door to investigate further. The won’t return text, email or calls. Indicated something may have been shorted due to mice. Since they didn’t finish or will call me I tried another mechanic. He indicates code 141 and suggest replacing the airbag control module . Since it’s a very expensive part and a much different suggestion does anyone have a good suggestion? Thought of buying a used one but concerned I may just buy one which has already deployed or faulty too. Thanks

And if you replace the airbag control module, you will need to code it to the car; read "you need a PIWIS unit"

Seems I read if you install a new one you have to have it turned on or activated but I thought I read someone else bought a used one and just swapped it out and all was corrected. I’ve spent $1000 already and getting no where.����

It is more than just "turned on", it is coded to match the equipment in the vehicle, which changes with various models. If a used one works, it would be pure luck that the settings were the same, a new one will carry no settings, so you have to tell it what car it is in.

And no one ever said these cars are either cheap to buy, or to maintain.

Thanks for the helpful input once again. The mechanic wanted $1600 for a new one and I got a used one on the way for $50 so my fingers are crossed.

I’m reading various opinions on the proper way to swap them out. Turn key to on and disconnect battery or remove key and disconnect the battery? Also read waiting times of both 1 and 15 minutes before pulling the module. Any pointers? Thanks

Disconnect the battery a leave that car alone for a minimum of 15 minutes before touching anything in the air bag system. In my shop, we also would put a static grounding strap on any technician working on the system to prevent any potential for a static discharge to the car which could set the system off.

Excellent, thank you.

It was the control module and with a used one of the exact same part # which came from a Boxter I was able to clear the codes and light with my Schwaben.
