Hoping it wasn't going down that route, do you have warranty?
Look at my comments in this thread when I had TCU issues

To be honest, I can do without the live stuff, since I can use Waze through CarPlay and the InControl stuff works fine, so I’m not missing anything I had previously.

Given what the TCU does, I’m not inclined to change it and the likely ensuing hassle and cost.

I don’t have a warranty, so that definitely puts a nail in that particular coffin I reckon.  Got - 2017 SDV8 Autobiography in Loire Blue

Maybe you will be lucky just a VSS update is all that will be required? 2018 SE SDV8 4.4 Byron Blue

Possibly, I’ll ask my local Indy if that’s something they are able to do. Got - 2017 SDV8 Autobiography in Loire Blue

Hi Alan,

Sorry you’re still having trouble

If you can get the Indy/ Dealer s/w update to S22A through Pathfinder this could fix the problem, but otherwise it looks like replacing the TCU  “If it ain’t broke, don’t fix it” -where’s the fun in that?

Thanks Gremiln, I’ll ask the question but I’m not inclined to pursue it any further if that doesn’t fix it.

As I say, I won’t miss what I haven’t had  Got - 2017 SDV8 Autobiography in Loire Blue
