Looking for some advice . Driving home today I set my DCC as usual on the motorway, set for 3 bars 70mph. Headed off on a 2 lane stretch on a straight road. The system acted really weird when it saw a car in the inside lane and braked quire hard. This caused the guy behind me to do likewise and give me some hand gestures.

 

I turned it off and then on again and it did the same. I have never seen it do this in the 18mths I have had her

 

Im guessing the beam from the radar may have come out of alignment. So what happens next , what should I do as I imagine a dealer re-cal will be expensive , is it covered under my warranty?

 

All advice greatly appreciated

The DCC takes account of vehicles in the right lane as you approach and slows the car to, presumably, prevent undertaking.

 

Long shot, maybe, but if the DCC is reacting to a car in the left lane (as it should if driving abroad - for the reason above) maybe the "driving on the right" option in the system has been selected accidentally.

 

Apologies that I can't remember the exact wording of the option, or where to find it in the car's menus.

its the undertaking feature u've experienced there.

it can be disabled via VCDS/ObdEleven adaptation changes.

i disabled mine via vcds.

 

if ur ACC radar is off, and needs recalibration - its going to b expensive, and given previous discussion - dealers won't cover it under warranty!!

 

 

and just to b clear......

DCC and ACC r two different things

 

DCC = Dynamic Chasis Control

ACC = Adaptive Cruise Control

 

and just to confuse things, Audi and VW have the next level ACC called Dynamic Cruise Control (DCC), currently not available in the Skoda lineup.  this version of ACC uses speed posted signs and gps data speeds to automatically slow down the car when approaching curves, roundabouts etc etc.

@cardo @Greezy56 it's in the light sub menu iirc for the head lights. Left or right hand traffic. Worth having a go at this.... But if it's set to right hand traffic, it means someone's been dazzling people all along LOL

Crap, I was about to post a question "does anyone know if..." what you described is possible? Ie. using a dynamic speed limit based on the road signs that it can already detect. I mean the hard part was the TSR surely? Since we already got this why couldn't it be used for the ACC...

Because the TSR system will only work on clean and unobstructed signs.  If it misses them then you could be at the wrong speed.

Undertaking is putting people in Coffins etc.

Over taking on the inside is legal but the car using ACC will put your car into a pause mode until you touch the accelerator and then it will carry on as normal. 

There's undertaking and passing bad drivers in the middle lane. I see may poor drivers sit in middle at 50 in a 70 stretch. if I go at 60 , I merely pass them not undertake. It would be unfair if the PO PO decided otherwise.

Its like middle is safe

 

No need for coffins

And BTW I meant Adaptive Cruise , sorry for saying DCC , if any snowflakes have been offended , my apologies

Can you please tell me how you disabled this via vcds? I would love to change this on my car.

Undertaking Prevention De-activation

 

Controller 13-Auto Dist. Reg

07 - Coding 

Byte 02, Bit 5 to 0=Deactivated

 

Untick Overtaking_right_prevention.

Once done, make sure you reset the Driver Assist, otherwise it will disable TJA below 65km/h.

@Gizmo - happy for you to add this to the VCDS Tried & Tested list.

Thanks. It worked. 

 

I also made screenshot. Looks quite different.

good to hear it worked

yes, your is very much different.  out of curiosity - wat model year is urs?

 

the "automatic_driveway" is related to traffic jam assist. i.e. it will stop n resume, in combination with ACC, hence TJA.

the speed_limit_assistent and curve_assistent i believe is relation to the Dynamic/Predictive ACC, but i don't believe this works on any Skoda models yet. 

sadly, simply activating the checkboxes is not enough, as Predictive ACC is a SWaP secured feature with an entitlement code, as well an associated data parameter table.
 

its certainly there for some VW and Audi models.

I have a MY18. But build in August 2017. 

The acc is set to not allow undertaking if you move on to the third lane overtake legally returns to normal cruise

Mine is MY17, built March 2017.

 

I notice u have an LnK model - it should have TJA as standard.

 

I'm surprised why urs then, doesn't have the automatic_driveway coding?????

 

Unless it's been moved to another byte location with MY18 models.

Yes i have TJA. It drives away automatically when its only stopped for a few seconds. After that i have to pull the stalk of depress the throttle. 

 

Also the lane assist works below 65kph. 

Is it possible to have "normal" cruise with VCDS if  you set for example minimum distance to car ahead? 

 

Adaptive cruise control is driving me crazy in motorways because I cannot control my speed when I'm closing (for example) truck driving  80kmh, my speed is 110kmh and some BMW overtaking me at 130kmh lane next to me. I would like to give BMW space to pass, and then switch the lane to overtake truck (after BMW).

 

But now, my 2019 Superb L&K recognize the truck and speeds down - even my car could go same speed as it has without crashing to truck... 

Can't answer about "normal cruise", but one option would be to reduced the setting that controls the distance to the car in front.

If you make it only one bar showing on the maxi-dot than you will get closer to the truck before cruise control slows your car.

 

I have not really tried this out so be careful when you first test it on the motorway/autobahn/autostrada...

This is the main reason that I hate ACC. With ‘normal’ cruise, it is easy to time your overtake, but ACC brakes too early.

I have mine set for the shortest distance, which is still too far on the motorway, but let’s you drive too close at lower speeds. 

I find ACC most comfortable set to 'Normal' mode and with the default three gaps distance setting.  In @Judge2's scenario this results  in coasting early allowing the BMW to pass with no braking and only a small loss of speed. Previously I'd used the 'Sport' mode with a short distance but found this would get close to the truck then brake sharply, much more obtrusive.  I do shorten the distance setting when the road is busy so it doesn't leave a tempting gap for others to fill.

I’ve found that even on the shortest setting, it is too slow to respond when the car in front accelerates, someone then pulls into the gap that has been created and ACC brakes, causing another gap to develop.

It's an assist system, not the driver. I agree it doesn't respond quickly enough when the car in front accelerates, but it is easy enough to give it a hand with judicious use of the loud pedal. Equally it is also easy to disengage it and brake manually when the brake lights go on half a mile ahead on the motorway, then re-engage at a lower speed. I toggle mine up and down between zero and three bars depending on road and traffic conditions. I'm still just as in charge as I was before I had ACC, but I drive in a slightly different way now. Fifteen months in, I love the system and I'd never go back to a car without ACC.

A wee update in mine , told the dealer of the problem , dealer uninterested and says come in at next service.

 

So driving on A9 going to Aberdeen yesterday , Tractor , big farm tractor  in inside lane. Im doing 60 , he doing prob 40 and just as I get to his tail end the crash mitigation warning and the car abruptly brakes.

 

Some one behind me would have found it hard to avoid collision with me.  So I reset it on the journey , 5 mins later Adaptive cruise not available and shut off. 5 mins later it was back and available.

 

This system could be deadly , I kinda want it for long drives but ****ting it now to use
