Radar / Adaptive Cruise / Emergency Brake - Questions and Issues

[DP Vic]

Hi fellow golf enthusiasts,

I am wondering if the dealer has buggered up with the front radar on my Golf. I have seen pics of overseas models where it looks like glass is visibleNew Style Radar - GOLFMK7 - VW GTI MKVII Forum / VW Golf R Forum / VW Golf MKVII Forum, where as with mine, looks like plastic is still covering it??


Any ideas?

Cheers,
Dan

Not 100% but I think you may have been shafted

Does it work? I mean if the features that use the radar work (adaptive cruise) then I guess it's good?

you need to be careful washing them apparently. you can't jet wash the front of the radar panel.

Mine has a round dome there. Radar works in mine. Should be easy to test though...just get behind another car, set the cruise (suggest using the longest follow distance) and see if it brakes with the guy in front. Of course you'll want to be ready to brake yourself if it doesn't. It's possible they've changed the sensor design, but I'd say it looks like it's not fitted...

uhhh, mine is dome and works.
just had a look on carsales and GTI models have them flat, highlines have dome ones.

Thanks All - the MY 14 models have a redesigned radar from what I have researched online (flat instead of dome shape)....

It works with cruise control on (slows down/speeds up & even stops with the traffic - really cool!), but I trialed the city emergency brake (front assist) with a big bag filled with balloons (about 1.5m wide and 1m high) & drove the car towards it (20 km/h) and it didn't even brake like the manual says it should.......

As much as I am loving the car, I have the dreaded wiper smear again - dealer has already changed the blades once! I'll get them to check out the radar when I take it back for the wiper blade to be changed....

Don't know about yours but I was under the impression the City Brake works when something SLOWS DOWN in front of you but doesn't work if the object is stationary. Mine definitely works in that scenario as I had an opportunity to test it the first week I had the car.

Came to a screaming halt and I still had foot on loud pedal. Not game to try it against a wall or similar.

This YouTube clip demonstrates what it should do

Obviously improved since 2010 I guess.

My MY14 is flat too and looks like yours. EB is working - it had a couple of little "freak outs" and slammed on the brakes. Adaptive cruise is brilliant. Best $1400 bucks ever spent. When you get into Economy driving / coasting etc another little extra in this pack you will appreciate the excellent "extra" fuel economy also. I'm averaging just under 5L per 100km over 4000km

some research, triggered by my curiosity...
also I can confirm that my MK7 103 delivered in Oct 2013 (built in Jul 2013) is also MY14.
vehicles manufactured after week 28 in 2013 is seen as MY14. (same as MY13 MY15 etc.)


“I have the part numbers for both the Golf and the A3 but I'm not sure they will tell you if they are interchangeable.

Golf - old - Radar Unit - 5Q0 907 541 G
Golf - old - Trim - 5G0 907 461

Golf - new - Radar Unit - 5Q0 907 561 A
Golf - new - Trim - 5G0 907 225 B

A3 - old - Radar Unit - 5Q0 907 541 F
A3 - old - Trim - 8V0 807 224

A3 - new - Radar Unit - 5Q0 907 541 H
A3 - new - Trim - 8V0 907 224A

Quite how significant the letter change at the end of the part is I'm not sure, but it does appear that the units used on the Golf and the A3 and the same or very close apart from the trim.

Make sure you are sitting down when you read this next bit.....

Both old and new units on the Golf cost £1,004.56 for the Radar Unit and £2.90 for the trim
For the A3, again the old and new units are the same price - £1,066.97 for the Radar Unit and £3.05 for the trim.
£62 more when you buy it for an Audi than buying the same thing for a Golf.”

“Having found the radar sensor in the Golf section I had another look in the A3 section and found the details. The Golf shows a round one and then a rectangular one but it seems Audi could not be bothered to change the drawings and just changed the part numbers with effect from 16/9/2013. I would assume that if it changed shape on the Golf it also changed shape on the A3.”

“actually the flat ACC is up to 150Km/h and the other one is up to 200Km/h

here you go : Driver assistance systems - Predictive Emergency Braking System - Speeds below 30 km/h (18 mph) , Speeds over 30 km/h (18 mph) , Multi Purpose Camera , Stereo Video Camera , Long-Range Radar Sensor , Mid-Range Radar Sensor , Stereo Video Camera

Driver assistance systems - Predictive Emergency Braking System - Speeds below 30 km/h (18 mph) , Speeds over 30 km/h (18 mph) , Multi Purpose Camera , Stereo Video Camera , Long-Range Radar Sensor , Mid-Range Radar Sensor , Stereo Video Camera”


“mine is from end of October as is my co worker's one. built same week and received same day.
Guess what:
I have the round and he has the flat
i have driver assistance pack and he doesn't
I can go up to 200kmh and he can go only to 150”

Thanks GeckoZAO. I was wondering what the difference was between the flat and domed radar sensors.

[Lem2808]

My GTI has the flat version.

I also believe they made the new version harder to steal. They were being stolen in Germany and whatnot.
