I had my car in for an update of the PCM and service about three weeks ago and was upgraded to version 4.76.

How did you get it upgraded? Mine is version 4.63, which I told to the SA and he said he looked up the car by VIN and there are no updates. My car is a 14 C4S

What does the update from 4.63 to 4.76 do?

I recently bought the car and there was a recall on the PCM S/W.

Mine was also upgraded to 4.76 from 4.41 this week. Advisor said there was a campaign to make the XM radio more reliable... or something like that.

When I took mine in for an oil change and PCM software upgrade, I was told they could not upgrade unless I had a complaint. After some negotiation they upgraded my 4.75 to 4.76

Looks like I have to go in with a complaint!

Pretty ridiculous if you ask me - why can't they just upgrade it?

Does complaining that you're not on 4.76 count?

freeman

apparently not according to my SA. must have an issue.

I am taking mine in Monday and my SA already has me spotted for the upgrade, I did not have to say I had any problems. My SA is always pretty good about this so I am pretty lucky.

if car is in warranty period , dealership service encounter must document a complaint or problem in order for them to be reimbursed by Porsche


a service advisor who values his job will never grant you " dealership goodwill " if the factory will pay for the tech's time

What kind of complain would get them to upgrade the software?

severan

Bluetooth issues... Phone disconnects at times... ect

Doesn't updating the maps also upgrade the PCM?

I'm on 4.75. Car Build completed in July 2015.

What's the difference between 4.75 and 4.76?

freeman

4.76 is supposed to cure disconnects
