I tried holding the power button while on the BSOD and the infotainment rebooted up again. weird. Eventually just shut down again. Error message says no valid software release.

 

Any update ? Same problem on golf 1.6 TDI 2016 after battery replacement...

 

@Francesco01 The whole infotainment system "brain" had to be replaced by a dealer (required programming) and cost over a $1,000. The screen was fine, so that saved a little money, but all of the guts (aka the "brain") are in the glovebox.

Apparently, these units have problems with the memory going bad, like total failure. I tried having them re-flash the memory, but it didn't work at all.

It is really odd that it happens after a battery replacement, but it sounds like the battery failing causes an electrical blip that results in the memory being damaged.

 

Just wanted to share my personal experience resolving this issue in case anybody who finds this post via Google is looking for a solution that does NOT involve replacing the hardware / head unit.

Here’s how the situation played out:

• My car battery was toast; asked my neighbour for a boost
• His compact jump-starter did not work, I suspect this caused the infotainment system issue
• Once he used his car to give me a jump instead, my car boosted successfully
• After 5 mins of driving, the infotainment system crashed and up came the EMERGENCY UPDATE blue screen
• Replaced my battery the following day; the infotainment system worked normal for 5 mins, then crashed + blue screen
• Did a hard reset on the infotainment system (i.e. pressing down the power knob for 10 secs); once again, worked like normal for 5 mins before inevitably crashing + blue screen

At this point, I started scouring the Internet for solutions. I found a website that had several firmware updates available for download, but unfortunately, for my specific firmware version (MST2_US_VW_P0504D), no such update exists. I called my local VW dealership just to get a feel for what the worst case scenario would look like for me: they said replacing the head unit alone would cost me $2k after taxes, and that’s before charging labour and a diagnostic fee...

That was enough motivation for me to keep trying to find a solution, and ultimately, I did. All the instructions for this patch are located here and easy to follow. This is also a helpful link that will cater instructions and tips specifically to your firmware and head unit. My head unit was manufactured by Delphi, but other VWs have Technisat / Preh head units.

If anybody needs additional help with this, I’ll do my best to guide you personally. Major shout out to the VW car enthusiasts around the world who have created such a helpful community online, it is thanks to them that this solution is possible, and why I feel obligated to pay it forward and help save the next person who experiences this issue from getting scammed by the dealership.

 

Any luck?
