Re: audi pre sense

Mine has given a couple of alerts when cars in front have braked and turned suddenly, just a warning ding and on the dash but no braking until yesterday. I was driving in roadworks on a narrow country road, with the offside lane coned off and workers there, one of them moved towards the middle of the road, still the other side of the cones and the car braked to a stop. A bit of a shock but it is reassuring that it worked as it should and I now know what to expect.

I also had the pre-sense trigger on a narrow country road as I took a sharp bend in bright sunshine with shadows on the bend. Not sure if that would have anything to do with it. Initially I wondered what had happened but then recalled reading about it on here. I'll be mindful the next time I'm travelling that road.

I have had pre sense operate 3 times in the 3 months we have owned the car. 1st approaching line of traffic stationary at traffic lights, lift from accelerator allowing car to slow, cars in front start to move away so no need to break - bang pre sense hits brakes. 2nd driving along B road being approached slowly by tractor cutting hedge, pull out to pass - bang pre sense hits brakes. 3rd driving in town, car in front pulls to centre of road to turn right, I continue to pass on nearside - bang pre sense hits brakes. At no time during any of the incidents was I in danger of hitting anything. Fortunately I was not being closely followed as I believe a collision from behind would have occurred since if I don't know the car is going to stop how can anybody else.
I have been informed by Audi that this cannot be switched off as it is a safety feature.
Audi must be lobbied to provide the option to disable this feature in the ecu.
Without this option I must get rid of my Q2 which in all other respects is admirable.

I bought my Q2 as ex demo.

ACC and pre-sense were flaky. A trip to the Agent found an incident had been logged, but a software update and "reset" produces good ACC.

Still not sure about pre-sense. Tested and found OK, but I don not want to construct an "incident" on the road to test it out. Might look an idiot in Court explaining myself.

A colleague with a Volvo only had an incident approaching a mirror outside a church! Go figure.

After having the car for just under three years I had the Audi Pre Sense message come up twice today for the first time.
The alert went away after a few seconds and the car did not brake.
There was nothing to trigger the alert that I am aware of

Ironically this happed on the way to the Audi dealer, car was booked in for an MOT and brake fluid change, then it happened again on the way back home.
I asked the dealer to check the car when it was in and they advised nothing was found.

I called the dealer back after I arrived home, they advised on changing the sensitivity down and keep an eye for more alerts
They also advised to check there was no dirt affecting the Pre Sense camera/sensor but could not advise where it was located on the Q2.
Does anyone know the location of the camera/sensor and have you had any similar advice from the dealer.

Not sure if it can have any relevance on false alerts but today was very grey and windy here in London

I was not aware the car had Pre Sense fitted until today 8-)

I get this sometimes. I find that ice builds up and obstructs it, especially in the morning as it’s way below freezing here. Also if it’s snowy then it stops working. Wind shouldn’t affect it but you might have got a leaf in the way or some debris that was then swept away. Iv not had any problems with the pre-sense system. Thinks it’s great. It is a bit sensitive sometimes, like it detects a parked car but I guess I would have been on the trajectory to hit it at that point in time so it makes sense that it gave an alert.

I checked with Audi UK today if my car has Pre Sense installed and they advised it should not.

So not sure why the car thinks it does, it is now booked to go back to the Audi dealer in the late Feb to be checked out.

Mine really proved it's worth when the car in front went in the back of a near stationary box van on the motorway. The Q2 was halfway stopped before i knew what was happening.

The occasional bleeps are a small price to pay.

I thought it was standard?you can check in the MMI anyway, go to vehicle settings and it should be there.

Although the pre sense is a great idea I have found that when driving down narrow country lanes ( which we have plenty of in the county of Dorset, UK) and approaching a sharp bend the pre sense will sometimes activate. This can be quite scary.
