Lowering and Adaptive Cruise

[BigD]

Are you sure you're not confusing adaptive cruise with adaptive chassis control or dynamic chassis control as it's now called? I can't see the cruise needing calibrating if you change a spring? The chassis control on the other hand would make an element of sense, however i'm sure some people on here have lowered their cars with no problems with the chassis control.

Is it not to do with recalibration of the radar sensor for perfect alignment on the new lowered stance? Imperfect alignment may well mean that you get lots of false alarms, or worse, it doesn't pick up anything much. Finding it hard to believe that it's a 6 hour job to adjust alignment to have a perfect response window at a certain distance.

Maybe, i know Wigit has lowered his R and i don't recall him reporting any issues?

Still....6 hours labour for what is assumed to be an alignment. 5 hours scratching their heads and polishing their spanners, 1/2 hour tea break and then that Eureka! moment when they realise what they need to do in the last 30 mins? 

Or maybe they need the bumper off to do it all properly?

It's not hunter alignment it's new kit that does all the driver assistance (intervention) systems and the Audi techs need training for it...

Just had a though....there must be some tolerance in the sensor as the difference between a full loaded car and just a driver must be accounted for...??

And thinking about it....

When we had the springs fitted one of the suspension angle sensors became detached and one of the many faults that came up was ACC/City brake unavailable. So ill hazard a guess the system uses inputs from the suspension angle sensors.

system works fine for me on the R and had no issues, secret is get the car properly aligned after, there is a far amount of adjustment on the chassis especially at the rear

Some of the springs also state "DCC Compatible". Possibly meaning these don't need alignment?

I have no issues with mine, but the vw guy tried to blag me saying my acc wouldn't work now id done it, tbh i think he just couldnt stand the site of someone changing a VW...
