Hi all,

I've been happily driving my mk4 for the last 5+ years without many issues. Besides the occasional unavailable front assist, infotainment black screens and the inability to connect to carplay. Carplay not connecting was annoying sometimes but almost always fixable by rebooting the system. Carplay is the only thing I use and I didn't care much about the infotainment software itself. During these years I have had a few (maybe 5 or 6) requests coming in for OTA updates. I always accepted these and didn't think much of it.

Now the last few weeks Ive been looking into upgrading the tech in my car. I thought it would be nice if there was custom software or a jailbreak available, so I could get more out of the screen and solve the slightly annoying issues. This is where I discovered I'm still running v1664, pretty much the first version of this software. So none of these OTA updates I accepted actually came through..

Trying to update the software through the infotainment system resulted in endlessly searching for an update, even though I seemed to be connected with the server (the globe icon is white). This is where I discovered I'm a bit too late for any OTA update and the infotainment sucks bad, as many of you probably know. No feedback from the system about why things do not work whatsoever.

I thought well, I'll update the system myself. I'm pretty tech-savy and thanks to the great community I've been able to create a USB with v1941. However, trying to update the system with my USB, I ended up waiting hours for the update to continue past 0%, without any luck, and of course, without any feedback from the system.

I've tried some "workarounds" like rebooting the system just before running the update, or turning off the engine and opening the door after starting the update. But these didn't work for me.

After doing some more research it seems there are more intermediate steps (versions) I have to update to first, before ending up with the latest version 1985.

As far as I could find I have to follow this path;

• 1664 > 1810 > 1896 > 1941 > 1985

I'm hoping someone here with more experience could confirm this path, and also confirm this is all possible using USB instead of ODIS.
I'm also hoping someone can provide me with version 1810 and version 1896, as I couldn't find these online.

My system details:

• Device Part Number: 5E3035816A

• Hardware: H56

• Software: 1664 - MOI3_EU_VW_R6640L

• ABT hardware: H44

• ABT software: 2088

It would be great not having to go to a skoda dealer to get this sorted out, as this can be quite time (and money) consuming according to some of you.

Thanks in advance!

@pab567 has a good deal of knowledge regarding these updates I believe so maybe he could assist.

Unfortunately I don't deal with MIB3 units :(
