A8/S8 [Official] Audi A8/S8 facelift 2015

[Mr. Mercedes]

I've been driving yet another A8 3.0 TDI quattro over the weekend. I drove over 2,000 miles. If I'd bought this car with the radar cruise control I would take it back in disgust demanding a refund. It simply doesn't work properly. At one point it picked up a car in lane 1 of the motorway whilst I was overtaking in lane 2, and applied the brakes. This wasn't an isolated incident and it's happened on every A8 I've driven. Unfortunately, unlike the S-Class and 7 Series, you can't use the cruise control without the radar function. On top of this, there were around seven or eight other design faults with the car, such as where the memory buttons for the seats are placed just where you put your hand to open the door, so you end up unintentionally adjusting your seat every time you get out.

And people think we're ready for autonomous cars already?

My S3 used to do this all the time. It must be the way Audi is calibrating their radar cruise.

If you could do that I would be extremely grateful, as I suspect this will not be the last time I drive an A8 with the system.

Had a look I couldn't work out how to have non radar cruise control, so I think it's all or nothing, but I don't have the problems you had.

Thanks for checking.

What about when you're travelling on fast motorways cruising around 120-130km/h? you have a slow moving truck in lane 1 doing around 90km/h, and coming up in lane 2 is a faster vehicle that you want to pull put behind to overtake the truck. Unless you time it just right, you have to disengage the radar cruise every time, otherwise it slams the brakes on when it picks up the truck. And yes, I did set it to the shortest distance.

Radar cruise just isn't useful when the motorway is rather empty, which is why Mercedes and BMW allow to choose whether to activate the radar element.

I have not had any problems with the S8 ACC I had for two weeks...

There are no motorway's around where I live, but last year we went from where I live to Goteborg in Sweden, once you get to Hammar it's 2-3 lanes all the way, I had the ACC locked on 130kph passing trucks with no problems at all. Even in the heavy traffic passing through Oslo it worked fine, it would crawel through traffic at walking speed then increase speed when the traffic flow increased speed. It's the first car I've owned with it and I thought it did an excellent job. The A8 is an older car so perhaps the ACC isn't as advanced as the A6?

I have driven a 5 series with ACC I didn't turn it off, I didn't know you could, I had the car for a weekend and put about 300km on it, used the ACC for a 140KM round trip to to visit family, from what I remember it worked the same as the A6 system. But I ended up buying the A6, the 5er was a 520D Msport Touring, around where I live it's not a comfortable car, maybe it would be better on regular syspension, I don't know I haven't driven one.

Maybe you were lucky. I passed a truck (truck was in lane 1, I was in lane 2) and it started to apply the brakes because it picked up the truck. Not this example, but the last time I drove an A8 with ACC, it did an emergency stop because somebody performed a u-turn in front of me, even though there was no risk or danger at all.

Even in the heavy traffic passing through Oslo it worked fine, it would crawel through traffic at walking speed then increase speed when the traffic flow increased speed.

That's the situation where ACC works best. When the traffic is light, however, I found it to be a pain. The gap it leaves between the car in front is too big, so it's often filled by other vehicles, and therefore it will apply the brakes quite hard when somebody fills it. On other occasions, you don't realise the car which is some distance in front is regulating your speed, because you don't realise it has locked on to it. So after a few minutes you notice you're doing 105-110km/h instead of the set 120km/h, as the car in front gradually reduced its speed.

This is the fourth A8 I've driven with ACC, and at a rough guess I've covered around 6,000km. The issue wouldn't be so bad if you could deactivate the ACC part when travelling on motorways with light traffic.

I have driven a 5 series with ACC I didn't turn it off, I didn't know you could

You have to press and hold the button on the steering wheel (for a few seconds) which adjusts the pre-set distance it will leave between the you and the car in front. Holding it deactivates it completely.
