Hello!

 

While I was driving the "Front assist unavailable" popped up and ACC turned off etc. I was behind the other car on the highway, as it is winter and everything is kinda dirty with snow, mud, salt, etc. I thought that the front assist cover is just too dirty and pulled over to wipe it, but the problem didn't resolve, unfortunately. The other day in daylight I saw that the front assist grill cover is cracked in full length exactly on the middle, will attach an image for illustration.

 

As I'm like 99% sure that this is the case to resolve this issue I would just replace that grill cover, but as I checked some threads on the "Front assist unavailable" a few of them needed to make a re-calibration at the dealer and one guy had a scratch on that grill cover and as well needed re-calibration + change the cover, but either way, I see guys that just change the whole grill and there is no need to re-calibrate anything for that sensor.

 

So now I have 2 questions:

 

1) Will I need re-calibration after a change of that grill cover if that is the issue?

2) Maybe there is someone who had the same issue with a cracked grill?

 

Thanks

The grille cover over the radar is generally not made of ‘plastic”’ it is a special material to allow the radar to pass through without issue.

a crack could possibly cause interference and throw the beams out.

 

if it is simply a cracked grille then you will not need calibration as the grille plays no part in this.

what you have to ask yourself though is, if the grille is cracked, what has hit it and has it also knocked the radar until out of alignment.

Thanks for the reply.

 

As I checked today on a daylight that cover, there was a soft rubber on it, and the first thing that I could think of myself was that it could be a stud from the winter tire as I was right behind the car on my acc at that moment.

That is not a Superb ACC cover.

Looks like that from another Skoda model, on the lower grille.

 

The Superb one is in the centre of the upper grille, above the number plate.

 

Either way, no - u don't need to recalibrate if u simply change covers.

 

However given urs is cracked, it's likely it got knocked back far enough to disrupt the radar's alignment.

The photo he has shown is what looks like a Maxton grille with ACC that’s why it has the honeycomb effect to it.

 

might just be a picture for an example rather than what he actually has 

If this is only grill cover problem, then radar should start working after removing the grill. I think something hit the grill and that collision impacted also the radar unit. So probably you need to re-calibrate it.

For @JR RS attached the exact cover from my skoda, as I mentioned in the first post

That picture I took from the internet was just an illustration.

 

I removed the cover and nothing did actually change, will make an appointment with the dealership for diagnostics and will update after everything will be clear what actually is the problem, maybe will help someone in the future with that.

 

Thanks for the help guys.

Hello!

Back to the topic, the issue was that cracked grill, dealer changed the grill cover and calibrated the sensor. Cost me 160 Euros.
