Has anyone noticed this? If I wait for say a minute the change will be normal but straight away it is anyone's guess as to what speed I get.

Have found that the Tiguan ACC is not as accurate as my B7 Passat was. It would sit on selected speed anywhere, whereas the Tig varies by up to 2 up or down from setting.
Also dropping back from 110 to 80 for the large roadworks in our area it will whack the brakes on and slow you down really fast and quite dangerously if in traffic.. What i do is lightly apply some throttle and change it back to 80 and lightly lift my foot to override the setting. Much safer..Havent had your problem as once I get back to setting I just bump it up a couple and it goes there.
Depends on traffic conditions as it depends on what distance you have front assist set to as well. Mine is set to closest.

As Simon says if going higher it starts to accelerate immediately up to selected speed and you can fine adjust it while its doing it

what works for me in those situations is to turn off ACC and let the car coast down to the desired speed, and as it's coasting adjust the speed, then turn it back on once i'm near that speed. as you pointed out, the immediate braking can definitely be dangerous.

I guarantee that if you have set your ACC to 90km/h, you are already moving on the safe side of 90km/h - even in Victoria

I always hit the +1 up to 5 times after setting the ACC to the speed limit - verified with a GPS display such as Waze that an indicated 115km/h == 110km/h

Could any Allspace owners confirm their footrest cover is not stainless cover. I’ve just had a look at mine and it’s plain black rubber.

I have corrected my speedo to read exactly correct at 100kph.
Used both a TOMTOM and an Android GPS app to confirm

Its was 4k fast originally

How did you do this?

Another thing here, if you drop the speed back to 90- rather than 80, it won’t lower the speed as quickly, then when you’re going less than 100, click down to 80.

The system seems to be programmed to bring the speed DOWN to the new reference point in X seconds (maybe 5-8 ) so going from 110-100 is a gradual speed reduction (engine braking), 110-90 is with some brakes, 110-80(and 70,60, etc) needs LOTS of brakes to meet this programming.

You are correct but when two lanes are running at 110 right up to the sign its a bit hard to knock it back so i just use the accelerator to keep it going fast enough to gradually slow it down and then let it take over. Have to stay in left lane for the ones who cant read the speed signs as well. Wish they would stick a camera somewhere in the middle of the 8km of works. They would make a fortune from the mainly young female drivers who cant read but of course limits dont apply to them Im told

Ditto my Skoda Superb, it was rock steady solid once it was set, the Tiguan is rarely at the set speed. I think the Superb was better than the Tiguan even towing the race trailer which weighed about 800kg.
