I've been periodically getting this warning. Big red warning symbol along with warning sound - it's most disconcerting when driving!
After first couple of times I went into the dealer who found no issue with the brakes but blamed ACC. The warning continues an is never when there is any driving issue.
It's either the ACC or Front Assist being sparked by sometthing in front of the forward sensors so I dissable the ACC and Front Assist.
Trouble is disabling only lasts as long as the journey. Nxt time you start the ignition they are enabled again.
Is it possible to permenantly disable eg via OBD11?
-
Surely the better answer is to get the dealer to fix the issue? Or is the car out of warranty?
-
dealer claimed it was a feature of ACC. Apparantly (I quote the technician) the sensors can pick up a newspaper or even a leaf blowing in front of the car and warn of an obsticle.
-
I get it occasionally but always for an identifiable reason. Yours clearly has a fault so force the dealer to sort or try another dealer.
-
Mine always goes off in one very specific location but nowhere else. It is a local junction where the road bends to the right and "left" is actually straight on, which I take. The weirdest thing is that it goes off every time but absolutely nowhere else, and I've driven all the way down to Gibraltar. No longer makes me jump though, so I'll live with it.

If you disable the safety feature on the car that reduces your insurance group then if you do have an accident and it comes to light the feature was disabled then your insurance would be invalidated. Are you going to ring your insurer and let them know you've permanently disabled acc front assist? Is it your driving style? Mine always seems to go off when people decide they need to virtually stop to turn left into roads and the car thinks I'm going to crash into the back of them.
-
It triggers when it detects a potential crash situation and the driver makes no inputs to correct...
It can be obviously triggered by a dodgy radar reflection, but usually its not the case.
Maybe you just have slow reaction times?
Has the big X woken you up or has it gone on to apply the brakes for you?
-
What is meant by 'periodically'? I've had the warning on the dash a couple of times in the 8 months i've had the car, both times in situations that were easily under control at lowish speeds. Quite disconcerting as you say, but if you feel things aren't all as they should be then i'd be taking it back to VW.
Doesn't seem a good idea to me to be intervening in a vehicles safety systems without the knowledge of the vehicle manufacturer or your insurer.

I had the exact same thing on the A4 I just handed back. Same place on route home where road goes right, and straight ahead is a side road lined with cars parked outside terraced houses. The A4 would ping at me just as I approached the bend, then the warning could cancel as I went right.
Worse still was a full emergency stop the A4 pulled on me as I passed a large coach parked in a layby. Again, the road was curving right, and I think the A4's AEB must have seen the coach, and kept on seeing it as I approached the layby and was gently curving right. The brakes came on, and I could do nothing to stop the car from stopping. The coach driver was stood infront of his coach in the layby and looked at me like I was some kind of idiot.
Thankfully, the lady behind me was far back and able to stop without crashing into me. Lord knows what she thought I was up to!
I took the car into Macclesfield Audi and they said there was a patch for the AEB's software, which they claimed they applied. It did not happen again, although it would still ping and even snatch at the brakes at odd times. There is a road in Congleton where the slope changes abruptly. In wet weather, the A4 would some times ping and briefly apply the brakes as I approached that change in slope, as if the AEB was seeing the road ahead and mistook it for a solid obstacle. However, as soon as the car reached the steeper part of the road, the alarm could cancel and the brakes release. This would likely only last half a second.
-
Yep, mine has done it a few times also.
Generally when someone is turning left and I am going straight on and you can see nothing coming the other way so no you can happily go around, if you get to close it would apply brakes and/or light up the dash.
The system is unable to see and anticipate in the same we we can, it can't see the car is indicating and turning left.
I leave a bit more room now and turn slightly right earlier and all is well.

Boils my pi44 when people pull onto the opposite lane when cars are turning left. Patience is a virtue :whistle:
-
I meant to say CanalMike....
Do you often seem to see a strange icon on your dash that is the one that means you are driving to close to the vehicle in front?
If you do, its probably linked...
-
Mine has come on just the once and it was whilst I was coming down Sutton Bank in North Yorks in rather exuberant style :whistle: ....rather twisty and quite a gradient, presume it saw the next bend (trees & hedge) looming large and was concerned I hadn't?! :tongue:

From the VW manual (tsk, who reads the manual eh?):
The area monitoring system (Front Assist) has physical and system-related limitations. The driver may therefore feel that, in certain circumstances, some reactions of the area monitoring system occur unexpectedly or with a delay. You should therefore always be prepared to take full control of the vehicle if necessary.
In tight bends.
If the accelerator is fully depressed.
If the area monitoring system is switched off or faulty.
If TCS is manually switched off.
If the ESC is taking corrective action.
If there is a fault in multiple brake lights on the vehicle or on a trailer with an electrical connection to the vehicle ⇒ .
If the radar sensor is dirty or covered.
If there are metal objects, e.g. tracks in the road or metal plates used in roadworks, or traffic signs above or next to the road.
If the vehicle is reversing.
Under hard acceleration.
In snow or heavy rain.
In case of narrow vehicles, e.g. motorbikes.
If vehicles are travelling slightly to the left or right of your vehicle.
If vehicles are crossing in front of your vehicle.
If there is oncoming traffic.
With pedestrians that are standing, approaching or moving in the direction of travel.
In complex driving situations e.g. at traffic islands.
In traffic situations that are unclear, e.g. vehicles ahead are heavily braking or turning off.
When loads or attachment parts on other vehicles protrude to the side, rear or above the normal dimensions of the vehicle.
Switch off the area monitoring system:
If the vehicle is being towed.
If the vehicle is on a rolling road test bed.
If the vehicle is driven in areas other than public roads.
If the radar sensor is faulty.
After external force on the radar sensor, e.g. after a rear-end collision.
In the event of multiple unwanted interventions.
If the radar sensor is covered temporarily by any auxiliary equipment, e.g. auxiliary headlights.
If the vehicle is being loaded onto a truck, car ferry or motorail train.

Might've been easier for them to list when it will work :rolleyes:

You should read the limitations on ACC:
When not to use Adaptive Cruise Control
Driving in heavy rain, snow or when there are large amounts of spray
Driving through tunnels
Driving through roadworks
Driving on winding roads, e.g. mountain roads
Driving off-road
Driving in multi-storey car parks
Driving on roads with embedded metallic objects, e.g. train/tram tracks
Driving on roads with loose chippings
Vehicles without Inside Overtaking Prevention System: Driving on multi-lane roads if there are vehicles
travelling more slowly in the fast lane.
Objects that cannot be detected
Persons
Animals
Stationary vehicles
Crossing and oncoming vehicles
Other obstacles that do not move
For example, if a vehicle that has been detected by the Adaptive Cruise Control turns off the road or changes lane and there is stationary vehicle in front of this vehicle, the ACC will not react to the stationary vehicle
Bends
The radar sensor continuously measures straight ahead. This means that when travelling around tight bends, vehicles may be detected by mistake, or vehicles driving in front may not be recognised.
Vehicles outside the sensor range
Vehicles that are outside the sensor range but travelling close to your own vehicle e.g. motorbikes
Vehicles that move into your lane directly in front of your vehicle
Vehicles with extensions or attachments that project above the vehicle.

You can get some interference from other parking sensors should they send a ping out at the same times. I've been sat behind a number of cars completely stationary in traffic and suddenly the parking sensors will start going mental for a second and then disappear. It's feasible that this is also happening when ACC is on.
F*$king hurts though when it pulls a full emergency brake routine out on you at random. :laugh:
-
This is probably the only feature of the car I don't like. The ACC is terrible on busy motorway and is constantly slowing me down. I've also had the apply brakes now flash at me a few times but the car broke for itself for the 1st time the other day and it was not good. Was driving enthusiastically on a country road and approaching a 90deg bend, I was already applying the brakes and was about to turn in with a little trail braking when it suddenly applied them harder for a split second.
Not sure how it can be a safety feature if it can pull off random emergency stops on you when it's fooled into it by other circumstances !!!
Love the ACC limitations list though, Driving in multi-story car parks :laugh: really :rolleyes:
-
If your acc is slowing you down on motorways then you're too close to vehicles in front of you. It's exactly what this safety feature is supposed to do to stop you rear ending someone.

Really ? Mine reduces my speed way before getting close to other cars even when set to the lowest setting. It’s not like I’m about to drive into the back of someone !!!
-
Yeah but remember the 2 second rule :wink:
-
Had a loaner 2018 Polo while mine was in for warranty work - bonnet cable snapped - and it was prone to false alarms and then when I did run up behind standing traffic it did nothing. :rolleyes:
Radar works really well on the GTI and does an excellent job of spotting slowing traffic ahead in lane 3 of the motorway, sometimes even before I do. It does not like me getting too close to the car ahead turning left and that's about the only time I've had a warning on the dash. Good system, worth having.

I'm pretty sure that the ACC "responsiveness" is also dictated by driving mode, so if you're in Normal or Comfort it's likely to start slowing you down sooner (but more gradually) than if you were in Sport.

also depends on the speed of the car in front, I find if a car is in front of me doing say 10mph less it gets close before slowing but if I’m doing 70 and the car is doing 50 it’s a bit earlier
-
Yes it is, I find it works well with ACC ECO, I changed it in Individual (from Sport standard settings)
I found it a little disconcerting with ACC in Normal, i haven't tried Sport.
I also set the distance from car in front as quite large.
For me letting when letting the car take some control, i like a bit a wiggle room so I have plenty of time to react should the ACC not work how I would like.
-
Thanks everyone. Seems I've touched a nerve! Glad it's not just me though.
In my case I've never actually had the brakes activated (thank god), just the warning.
And never (in my opinion) justifiably - sometimes on a perfectly clear road, reasonable speed, nothing in front (or to either side) just...... bl**dy great red warning sign!
I'm going to buy an OBD 11 now (for other reasons) - can I use that to permanently disable?
-
I don’t know if it’s possible to permanently disable it. However, as mcmaddy has said earlier in this thread (reply #5) your insurance premium takes into account that your car has Front Assist.
If you do permanently disable it, you have made a modification that removes a safety feature from your car and you would need to inform your insurer of this. If you don‘t inform them and you’re involved in an accident where Front Assist could have intervened and either prevented the accident or minimised its impacts, then you’re highly likely to invalidate your insurance.
Don’t be surprised when you come inform your insurer of your intentions to remove this safety feature if they are no longer prepared to cover you.

Had the car brake itself twice recently, both times when the car was in reverse while in the process of tight manoeuvres.
The first time was while turning around in a narrow country lane, the second in a car park. Both times got the big red warning on the active info display, followed by a hard grinding of the brakes.
On both occasions, it seems the sensors thought I was too close to the hedge I could see through the rear camera. If the car had touched the hedge it's unlikely to have damaged the car, but it's reassuring to know that it's looking out for me and can see things that I might not.

You can turn off front assist in the menus on the new Polo. Turned it off on our GTI+ while experimenting and it leaves 2 large warnings on the instrument active display, so switched it back on. The Polo's system seems to work better than the pre-facelift system on my Golf, in that it shows identified cars in left and right lanes of your position if you're in a middle lane of 3. Detection is almost as patchy on the Polo as the Golf in that at times you don't get the "CAR ! CAR" warning when you know for the distance between you and the car in front, you shiuld be seeing it. In my Golf, the ACC sensor is more likely to pick up a car ahead in a lane left of me than straight in front of me (and always has, despite numerous recalibrations under warranty when the system threw up faults eventually traced to the system not being able to handle long winding sections of riad (like the northbound Tyne tunnel exit,).
Both systems work well at the maintaining a gap aspect of cruise control.

Old topic I know, but the Emergency brake caught me unawares yesterday.
I had just backed out of our garage, but my neighbours had done the same and blocked me from driving forward. Their daughter had nipped back into their house so I sat patiently waiting for their vehicle to move.
I crept forward at about 1-2 mph but still several metres away, when all of a sudden, my car slammed its brakes on and the Red 'Emergency brake now ' (or whatever it says) lit up on the dashboard.
I can only surmise, at the time, I think the young girl was running back to the neighbours car, and the sensors had detected 'an obstruction'. I was still several metres away doing literally walking pace though, so I guess my car thought it knew best and braked! I think next time, I will just remain stationary!
-
Does the automatic braking only happen on the newer models? As I've never experienced it on my 2014
I have seen the the red warning logo which also beeps . It happens when I have ACC on and it thinks I'm getting close to crashing into a slowing down car in front (usually they're turning onto a side road so slow way down before)
-
Nope, my 2014 gtd did the full emergency stop on me a couple of times. If anything the mk7.5 seemed less twitchy, i don't think it ever hit the anchors... It did b!tch, especially after I turned the sensitivity up a notch.
-
The only time mine has ever done the braking for me is reversing onto my own driveway! It just slams the anchors on for no obvious reason. I reckon it's done it 5 or 6 times in 3 years, so not often. It always brings out a torrent of abuse though!
Tell a lie, it did do it once in a car park when it thought I was going to reverse into a fence. I wasn't, I knew it was there, but the car obviously got uncomfortable :laugh:
-
Thats just manoveur braking, it doen't trigger the massive red "you are going to die" symbol...I mean on the open road... at speed.
-
The first week I had my mk7.5 GTD I was reversing into a space with a high curb and I didn't know the maneuver braking also worked on the rear sensors, scared the life out of me but did stop me from hitting it :grin:
-

Oh yes, that's right. I've had that once or twice. Road bending to the left, with a right hand turn which is actually sort of "straight on", and a car waiting to take it in a turn line. I guess to the car, it did look like I was just plowing towards another vehicle
-
Yup, its not that clever on the Mk7.... the Mk8 is definitely a leap forward with the sensor tech.
My Mk7 once took me from 70mph to zero on an off slip road to a motorway services.... quite the thrill ride that one - even more so for the guy behind me...
-
How fast are you guy reversing to activate the emergency braking? :grin: :grin:
