Just got a letter from Porsche about an ECU software update. Anybody know anything about this?
Not a chance, OTA updates wont apply to ECU and/or drivability updates. Those types of updates require the car be connected to a 12V power source, etc when you do these. There is a risk of bricking the ECU if things don't go right; so they will only be handled by the dealer.it is a software update, you should be able to do that when your Macan is connected to your home wi fi ??
Yes. I second this. I have noticed the maps updating when I’m on the road with no wifi. That said I have a 2022. Not sure if older models were equipped with cell service built in.It's just doing it automatically over cell connection all the time... I don't think it does it over WiFi.
The real question is could the Dealer ethically let you come in and not update your software?Yes. I second this. I have noticed the maps updating when I’m on the road with no wifi. That said I have a 2022. Not sure if older models were equipped with cell service built in.
As for the changes. I would be interested to see if it’s a net positive or negative for performance. Also can a dealer just automatically update the ecu without consent ? When I eventually bring the car in for the one-year service, I want to make sure I don’t come out of the shop and lose 20 hp without knowing about it.
They tried to fixed it back in February but apparently that didn't completely resolve the issue.Reprogramming the DME. Sounds like a winner. Whats it say?
Click on effected products. It says 2022 Macan. Sounds right
Click on the documents, there is one PDF. Lets see what it says
WND8 - Re-Programming DME Control Unit (Workshop Campaign) Well that sounds right. Whats in it? Sounds like the programmers messed up and there is a possible programming error so the cats don't quickly heat up.
You know that cool sound when these cars start up that everyone wants to always have? AFAIK thats the cats heating up as quickly as possible so emissions are as low as possible. Looks like a programming bug they had to fix, otherwise, well read the current lawsuits and settlements on existing Macans. One might presume they want this fixed ASAP.
And now, hopefully, we all know.
And on what basis are the “fudging the numbers” comments being made? Sorry, I just have an issue with careless throw away lines like this. Like referring to “stealerships”. Over.
