Mine has had 2 small OTA updates recently, prior to going in for service and recall/fixes - both installed OTA in under 1 minute.

It was also on map version 21.5 (2021, May) before the service, and within a couple of days, it had downloaded OTA the very latest map version 21.8 (2021, August)

Radio version also changed from 1.30.16 to 1.30.24 as a result of the firmware update, but haven't seen any obvious changes with that

Further to my previous post. My software version did not change after the update i mentioned in last post. I think it was perhaps a map update, so no OTA update that i thought i had.

So, a further, further update to my previous posts on this thread.
Quick recap - Randomly get the 90/110 road signs in dynamic roadsigns display, Sat Nav jigging around all over the place, and irregular and unexpected slowing down when under ACC.
Add to the list now fairly regulate SOS call errors appearing (there are other threads on this).
Diagnosed with a from camera fault 3 Aug this year, and despite me telling VW dealer it needed system update from 0270-0278 they denied all knowledge. Told me a 2 week wait for part. Chased in Sept and said they'd get back to me.
They didn't.
Rang Monday last, told someone would get back to me.
They didn't

Anyway, trip to Bournemouth last week. Got as far as Severn Bridge (from Cardiff) before SOS call error came up. Sat Nav started playing silly buggers in Bath (couldn't even work out which road I was on). stopped car, switched engine back on and system wouldn't load user profile - nothing. No radio, sat nav, anything on info screen. basically all info screen u/s. Luckily we had a road atlas. Remember them?

At a stop called my dealer - reminded them they said someone would get back to me. Person said service manager would call me back.
He didn't, but person who first dealt with my call did (and apologised). Told me part still not in and 4/5 others waiting for same camera part and although system said 2 week wait, he had no idea how long it would be - bear in mind I've been waiting since 3rd August so far.
Explained sat nav/ info screen issue, and he (FINALLY) told me there was a recall against the car for a software update. Told him I wanted that done straight away and camera will just have to wait until part arrives.
Now booked in for this coming Weds for an all day diagnostic and s/w update.
By the way, info screen didn't reset all day - worked the following day and been ok since, but now worrying it'll go wrong every time I get in the car.
Shocking QA issues by VW and for once, not very good service from my dealer.
Will update after next Weds.

Not good - be firm with them and persist

Print off that TPI I put on the earlier page that relates to the 0278 software version update for resolution of the ACC/mph/kmh issues and show them.

Mine had a service, the software update, the SOS software recall and another unrelated fault all fixed in one day, one visit, and that was with the garage not even starting it till after 11am, so it seems like a competent technician can do it seamlessly.

Ok, latest update.

Into dealer today at 8am. Just picked up now (4pm).
They applied the system software update 0270 to 0278, and say that that (should) fix:

1. Problems with road sign displays and the other ACC issues I’d reported (noted in my earlier posts in this thread).
2. Problems with MIB3 unit randomly freezing

They also told me they’d applied ”another update” for an outstanding recall that fixes the SOS Call error that’s been popping up on and off for a couple of months.

Looking at the screenshot of the system menu it also looks like they’ve also updated the navigation software and media codec (see pre and post images below)

Finally, and interestingly, you'll recall when the car originally went in for diagnostics on 3rd August they told me there was a front camera fault and I needed a new unit. Today they told me they'd taken the original unit out but then realised that the software update(s) actually fixed the problem with the camera (so apparently it WAS software not hardware), and they’ve now replaced the original unit.

So, all being well it’s all sorted. I'm off on holiday to Devon for a week next Friday, so will be making extensive use of sat nav (and possibly ACC) so we'll see.

Fingers crossed.

Hi All - Good news there is now an official recall for this issue from VW. Contact your garage and book in.

There was also a secondary issue that affects your SOS emergency. You would see a vehicle notification to call into a workshop and be unable to use your hands free phone correctly.this is also fixed.

I’ve had the upgraded software for a week or so. The original issue is now fixed but it appears that the ACC now does not sync exactly with your position on the road. It will slow down for the roundabout after you e gone past it. Also slowing down for stopped traffic is delayed.

I took a technician out to show him the problem. He was uncomfortable and reaching for the brake on about 4 occasions when the ACC tried to kill is both and didn’t apply the brakes!

Will persist with this issue with the garage for now.

Great news - how is it approaching bends and roundabouts. Mine is still sluggish at responding to the changing road so will go too fast around roundabouts. Literally tried to do 70 on a dual carriageway roundabout. (Although no longer doing 20mph in 30mph zones which didn’t seem sign post related.)

 

[davehep]

Ok so I’m taking my car in again for investigation due to the SOS issue continuing after the recall software update. It happens pretty much every time I go out low!

Good news though! I’ve found a way of rebooting / reconnecting. When you get the issue it’s usually due to low signal strength (my best guess based on mobiles phones dropping out in the same areas!), so press the red sos button and it will attempt to reconnect when the signal has returned.

This means you don’t need to turn the car off and on again. When it has reconnected it will attempt to call the sos service but you can cancel straight away.

Why the sos service is linked to the Sat nav in such a way that navigation becomes useless as well is anyone guess!

Hi

I've joined this forum to find out if anyone else has encountered a potentially dangerous issue with the ACC.

Several times now I have been joining a motorway joining from a 40mph road when the ACC decides that the current speed should be 110; this is the road sign reader part.

I'm not aware of any any roads in England that have such a speed limit but I do know that would be an appropriate speed in KPH on the continent.

On its own this isn't an issue. As 110kph on an motorway is roughly 68mph however... once the ACC decides it's driving on the continent (when I'm on the m42) it then changes the speed to 70 on the road sign reader. Unfortunately the part of the system that regulates the speed assumes this is still KPH and Slams the anchors on reducing to c44 mph (70kph = 43.5mph).

I WANT TO POINT OUT EXTREMELY DANGEROUS THIS IS WHEN JOINING TRAFFIC ON A MOTORWAY !!.

(Obviously as a competent driver I adjusted my speed immediately to correct the issue; I was in control not the pratnav!)

As you can see from the second picture the cruise control shows up in red when you accelerate back to 70mph.

This also happens when travelling on a 40mph zone near my house and slows down to 25mph!!

The car is 2 months old and the garage have pawned me off! I'm waiting to an engineer to call to explain to me why this is a feature and not an issue but feel that I'll be wasting my breath trying to argue the point!

BTW the car was clean (the radar and camera where not fouled up!) and there are no road signs joining the motorway or any signs that show 110 (even if they did it shouldn't read that in KPH!) .

The garage have run diagnostics and can't find an issue other than a small error a month ago that has nothing to do with this ( I think it couldn't activate the nav for some reason)

So does anybody else either have this issue or know what to do to get VW's attention!

Other than that it's a brilliant car
Even if it wants to kill me!

Are you in a golf? I have the exact same thing and I've had passengers record the incident a few times, the car emergency swerve and brake measures also pulled me of the road in an instant thankfully no one was hurt.
It pisses me off as I go to my vw dealership and explain and they seem as confused as I am trying to explain it.
They all have vw's too are they given ones that aren't fucked?
I was on the motorway and it just slams my brakes on I try altering but it hates doing as its told

Hi,
I wish I had read your post before I took delivery of my 2021 Tiguan just 5 minutes back after my first service. This happens to me every time I am on the motorway. And I have a newborn in the car. This is a very dangerous feature of an otherwise excellent family car. I was also told off by the dealership that this is a feature and not an issue. Your post makes absolute sense, never taught of the KPH angle. This is an ISSUE VW not a feature. I rely a lot on Adaptive Cruise Control because with kids in the back it car be a big liver saver, when you need that extra bit of support from the systems while you are negotiating a truce at the back and it does an excellent job except for this nasty glitch. I wish UK road safety board forces VW to fix this issue. I will also write to VW directly now that I have a clear understanding, thanks to your post. Will let everyone know what I hear back from VW.



kind regards

Their fix is nothing more than reverting the ACC back to the same functionality as the pre-facelift. How this effects the the overtake/undertake issue I'm not sure, we definitely had the same issue in the past, but haven't had it recur yet. vidmate online saveinsta

How do I revert to the pre facelift? Is it a setting I can tweak in the car or I need to take it to VW service technician to do it?

Check the software version your running. If it's 0270 it needs updating. I had mine updated from 0270 to 0278 & that cured the problem. I believe there is a further software update as well, remember seeing it somewhere on here.

I just had my first service a few days back and they updated my software but let me take a look and check what’s the number. Thanks for the tip Blakey. Cheers

 

[Jabba46]

Thanks for the advice folks.

I got the car booked in and after 2 visits I spoke to the technician who actually understood the issue.

They spoke to head hut and it's now waiting for Volkswagen to write some new software specifically to fix my issue.

If sounds like they have taken it seriously if VW in Germany have to write new code; so makes me wonder if I'm not the only one with the issue

They will take it very seriously, in the event of an accident where people are injured or even worse, the police will seize the car for investigation and the ADAS is part of said investigation. If found to be defective, then VW will be liable for prosecution. This is also true if you’ve had a small bumper bashing and the repair centre has done minor repairs, the ADAS has to be calibrated again, most don’t bother and if that car is then involved in a catastrophic accident, then the police will come a knocking on the repairer’s door. Even minor repairs like changing a windscreen, ADAS has to be calibrated, change wheel sizes from 18” to 19”, ADAS has to be calibrated.

Hope this updates the thread, but I am happy to report this issue was fixed by VW last week via a software update. I will check my firmware version and inform this group in a few days but it fixed it. Such a relief.

That is good news. Thanks for the update.
