this happened again recently - it's now almost 2 years later - and Porsche claims we have a software "fix" for this error - in my experience it's a harmless CEL - but annoying because:

1. it's not good form to sell a vehicle with random CEL no mater how harmless they are
2. and it's another round of diagnostics at the dealer with no actual resolution

this time was different however - there is now a specific software fix for this exact error

picking car up tomorrow - we'll see how this goes…

wonder if Porsche is just routing this error to dev:NULL

I have every belief this will "fix" the problem - but this is now two vehicle's - both more than $200k - both with trivial CEL problems - both with no "Known" fix for the issue - and both getting a software "fix" 2+ years after the problem was originally encountered - please dont' try and tell me Porsche is any better than any other car vendor…

My guess is somewhere along these lines. Engineers at one point in time thought it critical to know these values were outside the range, but along the way realized that it's more common than they thought and the car just continues on fine and ignores them. So this programming just tells the car to ignore it.

More proof that integrating control modules by outside suppliers brings problems that we will never think about.

I agree - my read is this a dilation of acceptable parameters for voltage flux - I hope it fixes the CEL problem this car has had - it sucks to own a premier product like 911 TurboS and have to deal with this sort of minor BS every few months - also CEL's block registration/emissions testing if they are frequent enough even if they are a "false flag" and do not represent an actual problem

given that there is an actual software update for this - I'm guessing it was pretty pervasive fleet wide…but no way to confirm that other than the fact that there is a "factory level" fix - i.e. a procedure, tech note, and actual software from germany to 'fix" the problem - I doubt that they do that for "one off" issues…

ipse dixit

Love how they qualify their results.

Did the clicking in the dash come back?

I agree - sounds like Porsche effectively put black electrical tape over the light on the dash. They did it with software... but same same...

no clicking that I can detect - I'll report if CEL comes back…

Cool. Just curious based on the work order from when you thought it was Really Fixed. It mentions clicking in console.
