Good morning, I'm bothering you with a problem that despite repeated searches I haven't been able to solve.
Here I found similar topics and expert answers and I hope you can help me. My RR Vogue 2019 sdv6 I think has a problem with the TCU...
- wifi not working no IMEI no MAC
- vehicle software without version
- SIM (under the armrest) not working
- USB (for music under the armrest) not working/deleting
- parking sensors slow to turn on
- rear camera most of the time the green/yellow/red lines don't work
- tire pressure message present at every start
Fortunately the Motorola MA1 Android USB module under the armrest works for now!
I also went to an LR dealer and after the diagnostics he told me that I should replace 2 control units for the modest sum of €4500... does that seem strange to me!?
What do you think?
Do you know the spare part code of the TCU for my RR, is it under the steering wheel?
Thank you for your patience and any advice is welcome

welcome to the forum..

first thing to do is to check your battery....a low voltage battery could be the cause. ... - .- -.

Stan, thank you for the welcome and the advice, I will take care of it as soon as possible... even if I think the problem is elsewhere.
I'll keep you informed, who knows, maybe it might be useful to others.

How did you get on? I’ve just bought a very similar cr with very similar problems! Current > FFRR 2018 3.0 SDV6
Past > RRS 2015; RRS 2005; RRS 2007

none of these malfunctions are related to TCU.
I bet faulty is IMC and / or ISC

Update on my situation.

My Wi-Fi and SIM card have not been working on my Range Rover which I recently purchased secondhand. Tried various resets without success.

Purchased a secondhand TCU from eBay for £50 . Switched out the TCU and found that Wi-Fi worked fine. Did try a couple of SIM cards from my mobile phones. Not sure if there were specific issues with the SIM cards, and didn’t mess around with them too much but they were not working but did seem to make more progress than before the TCU swap. Think they might need to be left alone for an hour or 2 to pick up a signal?

Used my scanner to try to adapt the secondhand TCU to my VIN, but it doesn’t have that function. Notwithstanding, thought I would see how I get on with the secondhand TCU, but then of course discovered that the smart key was not recognised. Needed to switch back to the original TCU and unfortunately the Wi-Fi problem came back. Also, with the Wi-Fi working on the secondhand unit, I did try for software updates but there weren’t any available.

So I’ve confirmed what the issue is, but not solved it as yet. I have read a couple of posts that suggest that Land Rover now have a software fix, but I need to give them a call to see if that is the case. Current > FFRR 2018 3.0 SDV6
Past > RRS 2015; RRS 2005; RRS 2007

I think an uninstall/ reinstall might be the way to go. I found these when searching for LR TSB's:-
