I had my 991 serviced yesterday and the SA found there was a campaign for my car—WLC8 - Replacing tank leakage diagnostic module. As near as I can tell, it has to do with the evaporative system and it communicating with the car. The SA said it was minor and if the module was bad, I would have received a check engine light.

Parts for my 2015 911 GT3 were:
000-043-211-10 PRESSURE SWITCH
000-043-210-07 AIR FILTER
I presume all 991s have the same issue and parts.

I didn’t receive a letter or email from Porsche and when I just entered my VIN on Porsche’s web site for open recalls, nothing displayed.

She didn’t mention a heat shield campaign for my car (that is a different thread). I created this separate thread because of these being separate issues, at least for me.

 

Hey Silverbird. Welcome to Rennlist!! We have a very good conversation going already. It's under the "Heat Sheild" thread. I'll link it here for you. You may need that service campaign, too. Take care.
