Adaptive Cruise Control questions
Hi I want to know if ACC on D3 A8 halts the car to a full stop in stop&go traffic and will it set the car moving again once traffic starts moving again? If so what model years should I be looking at etc?

There's a self study program document in the tech dump under common faults in the D3 section which should answer that -

According to that document you can only set it when at (and to) speeds of 30kph or more and it disengages if speed drops below 25kph. My (much later technology) Volvo can (in general) only be set at a minimum of 20mph but will come to a halt in a traffic jam and resume whatever speed the target is. It will however only resume within about 3 seconds of stopping, otherwise you have to press a button or "tickle" the accelerator to move off. And it won't sit forever on the brakes either, though that's a much higher limit. (And if there's another vehicle close in front to follow at a slower speed below 20 you can "set" and follow at those lower speeds, but it won't exceed 20mph until you set the target higher) |
The limits of ACC on the D3 are 20mph to 120mph. It gives an audible warning if it goes below 20mph. No idea about the other extreme.
The more recent D4 and D5 have much more advanced ACC systems that go all the way to 0mph, and will cater for the stop/start scenario of city driving/traffic jams. |
