Hopefully it clears up but my ACC would not turn on this morning on the way in, had to resort to actually driving, old school :rolleyes:

I hope this isn't the beginning of more faults

If ice or snow blocking the sensor was the issue then that's pathetic given the temperatures in the UK were not very cold.

I think that would depend where you are in the country, it was certainly cold and snowy here this morning.

But, always better to jump to a conclusion to paint the ID.3 and VW in a bad light...

Was there any ice or snow around?

It is one of the well documented issues with the early versions of the software, mine does it occasionally. If you don’t get a greyed out speed a couple of seconds after you select drive, then it means it won’t be available.

Turning it off and on again usually gets it back online.

I was only comparing UK temperatures to other parts of the world. A system like this should be capable of working in the conditions in this country - normally they are heated to prevent any build-up of snow/ice which works a treat apart from in blizzard conditions. I would also apply the comment to @njm106 's Renault (presumably), not just the OP's VW ID.3.

And what makes you think it doesn’t?

Tesla Bjorn didn’t seem to have any issues with it driving in Norway, and nor have I even in heavy snow. The windscreen camera image becomes obscured by heavy falling snow so you lose lane assist, but the ACC/radar carries on working fine.

I don't. It was not my suggestion that it was the cause of the issue and I was not agreeing with it. Given your experience it sounds like something else - don't jump to conclusions about what I say!

My previous two Golfs rarely had a problem, even in heavy snow. This is just another software bug which will get fixed eventually.

I figured it to be a software issue as there is no snow or ice and the car is parked under cover. Never had an issue with the ACC on the Passat.

Read with interest about the ACC comments - my 2's worth .. A cautionary warning about the ACC system (hopefully it's been improved / better built quality than back in 2014 !) ...

On my Golf Estate 2014 - approx. after it was 2 years old - it threw up an ACC fault while driving at 50mph, the fault wouldn't clear. Ended up taking it into a dealer under warrantee - they discovered that inside ACC/Radar unit, behind a bezel - a small mirror (the size of your small finger nail) had "dropped out" - It's essential for function of the unit. Then ensued a significant battle with the dealer who inspected the fault, they claimed it had been tampered with, but when I asked how or why? they couldn't explain? ... but when I asked how is this mirror fixed in - I was told it's "adhered" - so I said "glued"? after a battle of words - they agreed that "adhering" meant "glue" ... I then went onto say - so a device that is exposed to road vibration, extremes of heat/cold and can get hit with road debris, relies upon a mirror "GLUED" in? ... and then added - would you stick a picture to a wall with glue and expect it to stay there - under those conditions ... the mechanic and the service manager refused to comment.

Being told that I would have to pay over £1200 for a new unit, and it's set-up / alignment - I took the car away and took the matter up with VW Milton Keynes, who after threats of legal action - agreed to pay for the fix of the fault as a "goodwill gesture". I naturally took it to another dealer - who was polite and a pleasure to deal with - problem fixed, not happened again (fingers crossed) - conclusion - a faulty component with dodgy Glue !

Yep - My BMW 4 series used to have problems with ice snow Parking sensors ACC radar Sensor would become troubled with ice/ snow build up when driving in snow and start showing up alarms/ faults. It really was a transient condition and corrected its self when the snow build up fell off the sensors.

Snow one of the weather conditions that will cause disruption to our lives. It causes far bigger problems with transport this.
