Subwoofer control only returned for B&O cars. The *** cars have never seen a Subwoofer control in this generation of cars. The B8 had them and I do wish the B9 did too.
So as it turns out MMI FW 1316 didn’t work. It’s meant for a variant with the Qualcomm chipset, and I think the early calendar year 2017 and earlier A4’s used the Nvidia Tegra 3 chipset...at least mine anyway. Those of us with earlier builds will probably max out on 692, if it can even be found. Thanks Bruce for hooking me up though.
I stand corrected. Thanks for the info. Since my dealer refuses to do any updates even when documenting problems described in a couple different TSB’s I’m at the mercy of finding the correct FW myself that has the proper variant and trains listed in the metainfo2 file. I tried amending the file with remarks to skip variants and checksum, and enabled swdl in the green menu, but then I run into invalid signature, there doesn’t seem to be a way to force the update from a self install perspective. Clearly the dealer can do this, it seems.

At least I updated the VC
My story. I already said I am having CarPlay issues and their response was "It's probably the cable". It really ticked me off. I even showed them the TSB that DirkM posted, which is for the CarPlay.. Also I'm under warranty so there really isn't any reason why they shouldn't update it.
So I finally got a large enough SD Card and a fairly recent FW (thanks @bruce_miranda )! Is there a guide to update the MIB2 FW? I just see a bunch of options and all the way down, it just says "Start Update".
