My CS was just tinted and I now have an airbag fault light on on my dash. Any ideas?

The limited research I have done so far hasn’t revealed a lot of useful information. Only one thing looked promising and that was the seat positioning. Apparently if it is too far back it can cause issues. Worst part, I just put the car up for the next week (traveling) so won’t be trouble shooting till next weekend. Anyhow, hoping someone has seen this already.

Any indication which airbag triggered the fault? A lot of soap and water can get down inside the door and interior trim pieces when window tint film is applied.

I have no idea. The fault light placement in the dash is shown in this photo.


I will likely disconnect the battery when I get home to reset the faults and see what happens.

The same happened to me few months ago...At the Porsche dealer they did an "update to the software" and eliminated the fault.
then again it occurs when I had the car in a detailing shop...

Any comments? should be something wrong with the reset? or battery removal?

Ha! Same thing here—had the windows tinted and ceramic paint protection installed and now the airbag light is lit. I'll call the folks that did the work on Monday and see if they have any ideas, but it may mean a trip to the dealer. I'm curious if @rooster or @Julio C. Lavergne Rivera found a solution?

Completely unrelated, but maybe worth checking.

On my Mercedes, There was something under the seat that pushed the seatbelt wire into the seat track. The wire took some insulation damage when the seat was moved and grounding out on the seat frame. Caused all kinds of issues with the car and If I remember the events correctly, I believe the car went into limp mode. Googled it and found it was a common issue. Went out to the garage, found the short in a matter of seconds. Put shrink tubing on it, secured the wire back up to it proper position and to this day no issues since!

Electronics in cars now are so intertwined and sensitive to a simple fault.

A quick update: My window tint guy says he didn't remove any interior panels, steering wheel, etc., so he's surprised I'm seeing the fault light. He suggested I disconnect the battery for 10 minutes and see if it resets.

I may try that, but it's going into my local indie shop tomorrow for an oil change and brake fluid flush (Castrol SRF), so I may just ask them to check into it while they have it.

Got my car back from my indie shop this evening and they checked the code. They said it showed an ignition key fault, and when they cleared that the airbag warning light went out. Makes absolutely zero sense to me (or them), but I promised I'd report back. We'll see if it comes back or not…
