Collision avoidance assistance

[JAG]

Has anyone noticed the collision avoidance assistance to be overly sensitive on the Terramar? On a few occasions now, especially in extremely slow moving traffic, maneuvering between cars or reverse parking it slams the brakes avoiding a collision that isn't there.

I maneuvered between a gap in traffic out of a junction and the brakes slammed on, I reversed into a car park space between 2 cars and it slams it's brakes on, yet I reversed into a bin (at slow speed and no damage) and it done nothing, sensors barely made a noise.

It seems it has a panic attack when the roads are busy and wants to alert and avoid anything it senses.

Other than that. I love the car, dark void colour is amazing, senheisser speakers are great. And will be adding some site merch to it soon.

 

[Seriously?]

Is the sensitivity not adjustable within vehicle settings?

Same here ?
Especially sensitive during left turns or if pedestrians crossing.
Didn't find a way to adjust it btw...

It's the same across the VWG board. The systems are overly sensitive and the ability to adjust the settings have been removed.

Yes, same here. Just today it slammed the brakes when the car in front of me was turning right. I’ve got used to it but it scares me sometimes.

Dampness in foliage can play havoc on bends I find at times. You get more of a bounce back on the radar. I'm sure in the Ateca, the dealer quietly adjusted down the sensitivity with less false positives. Get none now apart from those hedges it doesn't like on damp days in the rain on bends but just the alarm, not the brakes as well. Early days it would pick up lorries turning in lorry parks off to the side ?.... hence why I reckon it was reprogrammed during a service or some clever re adjustment itself. You can only have so many false positives without the collision ?.

Hi , i notice the same today with the panic brake and it was so close that the car behind me drove right in me !!! I thought this system should avoid collition rather then make them ?? What i heard the whole vw concern have same problem so why dont open the eyes and fix them ??

Could you tell us how you explained what happened to the police? Did you notify the dealer?

Sorry if i was unclear , nothing happened luckly but it was close the car behind was good on the brakes in this case . No police but i have contact the dealer and waiting for recall on what they Will do . But my thougts is that the repairshop must look at it in the logs if they can see anything maybe ?

Probably front assist stopped the car behind, but without front assist in that car a different result. Best not to drive at the limits where you hear the squak warning, that is the initial step of slamming on the brakes. The system judges you arent going to stop from what it can see via radar and starts the process off. As I have said above I've had the warning with a large lorry turning around off the road to the left. Normally its just wet hedges / foliage on a bend where your speed and it not knowing it's a bend will trigger the pre warning off. If you dont want the warning in such conditions you drive more slowly and leave a gap .

 

[Kvarten71]

Yes, I understand what you mean, but I think the system is way too sensitive? I really wasn't driving fast and there was no danger of a crash whatsoever. Then you wonder if the system really works as it should? I've contacted the seller who will take a look at the car so I know that everything is in order.

ADAS calibration they get taken off to a shared local VAG service facility for calibration

Front Assist Calibration?

I got into a very minor fender bender where I slid on black ice into a tow truck at very low speeds. It broke my emblem, cracked my upper front grill and has scrape marks on my bumper. Before the accident, I was getting front assist not available due to ice buildup on the front of it. Now that...

If you download the Erwin manual you will find for sure technical details but it isnt something you can do yourself. They have Vag authorised equipment. Note abovd it says its something that a dealer doesn't do or cant thats because it goes off for specialist adjustment. As I said mine seemed to detune itself or I knew to keep within the parameters when it would scream at you.

Anyhow the process is this or similar:

Not something you can do yourself.

The issue with over sensitivity isn't caused by adjustment, it's literally because the system is set to a ridiculously high setting from the factory with no way of turning it down.

ADAS systems can generally be calibrated dynamically on the road now, there are few adjustments that can be done once fitted. The boards are only required if the dynamic calibration fails.

The equipment has been mandatory tooling in dealers for some time now.

It would be interesting to hear the rationale behind the decision to remove the possibility of "on board" adjustment, especially given that the high factory setting is known to cause issues.

If its pointing in the wrong direction does help I'd say.

It was removed late 2024, I've no idea why.

If the camera or radar are out of adjustment then the system shuts off and demands a calibration.

NCAP I'd say. They dont want people messing about with it unless within the bounds of the design parameters and they decided you are locked out of them. It would be another defeat tool to play an NCAP game.

Pulling dummies across roads to test how the car breaks then to have dealers and users fiddling with the controls to defeat NCAP safety features isnt one thay want. Why I reckon they have closed up adjustment via coding now to keep wandering hands out of the system and hackers that could turn the connected car network into a hackers Internet paradise.

It's the calibration equipment that James says is now readily available that they should be using and following those procedures. The tech master or whatever the guy the dealer calls him is critical. Duff practices in a dealership and they arent going to get down to the bottom of issues these days. Spirited tail gating and driving in an ACC convoy with one duff unit will lead to interesting results or impaired front assist due to rain..... There is ofcourse no accounting for wet foliage on the side of roads or banked roads. Then you just drive more slowly. Living in the land of 20mph if you keep to the limit all is good . The pesky we foliage doesnt trouble you on bends on roads.

The unfortunate thing now is most of these issues are software related. There's not much can be done by anyone at dealer level. It's manufacturer and product development that needs to take the baton.
