Radar / Adaptive Cruise / Emergency Brake - Questions and Issues

**armthehomeless** · 14-07-2015, 01:06 PM

Hi all,

Just wondering if anyone else gets intermittent "Blocked Sensor" errors on their MK7 Golf Adaptive Cruise Control?

I suspect it does it more going through tunnels/tolls (I'm in Brisbane). Is there any definitive answer to any interferences of the system?

I've taken it to the dealer who have seen the codes, but refuse to fix under warranty...which is BS.

But that aside, I'm just curious if this is a common problem.

Cheers

My alarm came up and it had a strip of bark sitting over it. When I cleaned it off and washed the camera screen cover it was all ok. Doesn't sound like that is your problem though. Keep pushing the dealer or try another one!

Yep, thought that the first time. But I've had it at least 10 times. And most of those have been within a short period of going in the toll tunnels in Brisbane

No doesn't sound like my problem. It is a real pain when the dealers ignore you. Keep pushing them. I pushed and pushed with a major problem with my Mk 6 and I refused to let up as my warranty was about to expire and surprise surprise it was a $3000 part that head office had to approve.

Go to a different dealer. I travel through Melbourne's Tunnels and Toll pointers never had a issue.

Did anybody find a way to actually test CEB? Ive got a old cardboard box from a plasma tv which I want to try the CEB with but am not sure what the actual procedure is. I tried cruising at very low speed towards the box but nothing seems to happen, or maybe I am breaking before the CEB kicks in. I dont really want to drive into the box as I'm a bit paranoid about scratching the paint work. I might need to find something softer to drive into, something that won't scratch the paint work. Bag filled with balloons as someone mentioned earlier sounds like a good plan.

I have to the ACC and that seems to work pretty well, and I've also had the Front Assist warning come up for me once while doing some "tricky" maneuvers.

EDIT: I hung up a blanket today and drive thru it and the CEB did not engage. I think it's because the radar has to sense something metallic as you can see in the video below when they test it on the VW Up.

Hi there

Hoping for some expert feedback. Picked up my MY16 R with DAP2 last week. Loving the car after two x GTI's. I'm a little concerned the Front Assist / City EB is not working. On the freeway I have seen the 'too close' icon where the total kilometres is displayed. However a trial using some stuck together cardboard boxes in the driveway didn't activate any warnings, the car just hit the cardboard boxes.

The function is on, it isn't showing any errors etc.

On a side note, I drove a test MY15 R and I noticed a yellow icon which turned to green within the right side display / analog speedo. The light was at about the 2 o'clock position about half way between the numbers and the centre of the dial. I don't have any such light on my MY16. I didn't pay that much attention to that light on the MY15, but I assume it had some function (that car was fitted with DAP, not sure if it was 1 or 2).

Any thoughts / help is greatly appreciated.

Thanks

You might try some foil on the boxes.

Hi Everyone,

How does ACC work with a manual with gearing up and down? As it applies breaks and you need to gear down will it still apply breaks? Same as when it needs to accelerate again, will it stop accelerating when you go to gear up?

I've been trying to find videos and answers and failed miserably so far.
