Myself and a couple of colleagues have the new A6 and have all found the driving/safety assists very dangerous.

The lane assist doesn’t always read the road correctly and sends you vearing off the wrong way and the brake assist has a complete mind of its own and slams on the anchors causing vehicles to emergency stop behind you. Has anyone else experienced these issues?

I bloody hate the car tbh, but stuck with it’s for the next 18mths!

I have had mine a few weeks now.
Not decided what to make of these 'driver aids' yet.

I haven't yet had it 'slam on' but it has dabbed the brakes on me a couple of times. A Little disconcerting but not too bad.

Of more concern, it has twice veered on me...
Once pulling out to pass a parked van, didn't indicate as nothing else around, and it tried to steer me into the van instead of crossing the dotted line in the road.
Second time on a constant radius right-hand bend, I must have got too close to the nearside solid line and it steered away just as I approached a centre bollard island separating the 2 carriageways.

This is more concerning than the braking. It's as well that it is just a minor tug at the wheel rather than a strong steering input.
Just keep a firm grip on the wheel!

What is more annoying is that, although you can switch these systems off, it defaults them both to 'on' every time you start the car.

I have an A4 with the Pre Sense system at the front. It can be pretty dangerous. I’ve I’m driving around Bristol city centre which has lots of curves and bends, it will identify people on the path in front of the car but I’m already steering left following the route of the road. I have no intention of mounting the pavement and hitting these people. But as I head towards them the car will go through the steps of warning, braking and then attempting to stop the car. I have a manual so if you’re not quick enough to apply the foot brake the car will stop and stall. It also causes problems if I’m just behind a push bike and I wish to overtake it. There are some sensitivity settings which may help. However saying that it did stop me from heading into the back of a Fiesta that decided to make a sharp left without indicating.

As for the brake assist thing I can’t work it out. Sometimes when I leave the motorway up the slip road and start to gently brake it will slam them on and can be dangerous. Other times, same speed, it will allow me to gently press the brake peddle as normal and slowly bring the speed down

I’m currently specing a v60 t5 which I think comes with similar equipment

Mine keeps failing then I get irritating warning messages for the whole journey. Takes a month to book it in to Audi to get it looked at. Pain in the fking arse.


And the tyre pressure warning sounds on a daily basis. I stop the car, check the pressures and what would you know, they’re fine.

All these comments are seriously discouraging me from getting new Audi. Might stick to one I have without all these gizmo or move to another brand.

Likewise. I was just about to order one but might change my mind now.

I wish I’d kept my previous generation A5. Never had any issues with it at all.

Reasonably sure you can adjust the sensitivity in the mfd?

I will look into adjusting sensitivity. I think I have seen it in the settings somewhere.

I don't want to put anyone off, These systems haven't caused any serious issues - just a little disconcerting on rare occasion and needs a bit of getting used to.

The potential upside of preventing a collision should be enough compensation for anyone.

Mines booked in to be looked at next month, I’m going to ask them to disable all the electrical stuff at fault if they can’t fix it. I presume a software update is needed.

I think driving requires enough attention without keeping an eye on car systems to make sure they don't interfere in wrong situation or cause any issues. I prefer to be in control of the car, rather than be controlled by not so perfect system and have to correct it, so it can save me one day (or not).

Just been out for a quick look.

Can't see any sensitivity adjustment.
There are just 3 items to change in 'driver assist' menu, Distance warning, PreSense and Rest Recommendation.
Of these 3, DW and RR can be switched off permanently but when you toggle PreSense off, it warns you that this is only 'until the car is next started'

So, it seems PreSense and Lane departure systems can be switched off but you have to do so every time you start the car.
Which is how I understood it to be.

As is the stop/start on my S4, however using VCDS I now have it on a 'memory' function so that it stays how I left it.

Not sure if this is the case with pre-sense or even stop/start on newer models though?

OK, found additional settings similar to above...

What is shown above is adjusting the amount of warning you get before Presense kicks in. Does not change sensitivity of the system.
You cannot switch the system off fully (only switch off until next car start). You can only adjust when it gives a warning of imminent braking if you don't react.

Mine is currently on 'medium' and as per my original post seems OK so far - no major upsets, no slamming on (so far!)

Similar for Lane Departure, you can switch off the system each time or you can switch off the vibration warning before it steers for you. You cannot permanently switch the system off via settings in the MMI

You should be careful messing about with these settings as I’m sure your insurance cost reflects these being fitted to the car and functional.

It isn't currently my intention to mess with anything. I have indicated from the beginning that I have no major concerns having these systems active. I am sure that Audi has done its research properly and that I will get used to the occasional 'intervention'.

Others have had more trouble than I and there might be some defect with their sensors or settings (or even driving style) to cause that.

Indeed, the ability to temporarily disable these systems has been provided by the OEM so it can't be a major issue to do so.

Must admit, i did read somewhere that early implementations on some VW's would cause the car to slam on when a plastic bag wafted in front of the sensors, but I haven't actually witnessed it (yet).
