Hi Scott - welcome to the forum! I've found the part that you're referring to and we have one available if you'd like to order. I would imagine that this can be done by a local shop, but the fact that the mechanic is uncomfortable around electronics and computers doesn't give me a good feeling about letting them do it. When you say does it require the shop to have a computer, are you referring to the scan tool? I don't think it's 'dangerous' if it's what I'm thinking - which is basically that the air suspension is locked in place and will not lower or raise the suspension. I do recommend getting this looked at as soon as you can to prevent any other damage. If you're going to be ordering the part, I would recommend giving us a call at 888-280-7799 and confirming with our Porsche part specialists that this part will work for your car. Hope this info helps and best of luck!
