Title: Mk 7.5 Front Assist
Post by: naxcars on 21 January 2018, 13:09
Do we think that VW have a design floor here?

Had the Vehicle Status for impaired front assist today after 700 miles.  quick clean of the VW badge and all cleared.  Surely a bit for rain and sleet shouldn't need me to stop the car and clean before a system operates without warning signs :(

Well on my previous generation MK7 (before the facelift) the sensor for the ACC is in the lower grill not higher up in the front badge as it is in MK7.5 cars. You would think being lower down, it would be more susecptible to debris and road grime etc. but both of the MK7 GTD's I've owned, have never had this issue ?

I agree, my Mk 7 GTI PP has never had a problem.

I had it come up a few times in the last snowfall, looking through the codings there is a adaption for a heated lense so I presume in colder countries it wouldn’t be as much of a problem

I had this a few times already. Usually crap got stuck on the sensor, once it decided to 'eat' a crisp packet an inconsiderate arsehole has thrown out his window.

The other time it was frozen over with snow and you could only see the centre of the sensor, the rest of the cutout in grill was covered in snow.

Had it for first time won M1 when it snowed just after Christmas. Once snow stopped it soon sorted itself .

I had this come on this afternoon - bit of a poor design - do VW expect you to stop, jump out and clear it every few miles in snowfall?   :sad:

Mine cleared after a couple of miles,

Normally needs a fair bit of snow to 'block' the view. I had a lot hanging down from my front plate and around the grill when I did have it in the snow.

The sensor is heated no matter what country you live in so it shouldn't be blocked ever.

Problem is the build up on number plate and grill on the old ones as it partially interferes with signal, at least enough to throw the limited visibility warning.

I've had it get bunged up by snow on both Mk7 and Mk7.5.

The first time I hit the problem on the Mk7.5 was the first time it snowed a bit - and I mean a bit.

I'm used to it not being available when it snows now.

TBH, its probably not conditions where you want to slacken your concentration off by having the car do its thing anyway...

I had it for about 5 mins yesterday on my MK 7.5. Never had it on either of my other Mk7’s  :rolleyes:

Am I wrong in thinking that when you see cars that have been driving in sleet or light snow the biggest build up of it is always around the badge, front grille and leading edge of the bonnet?

Mine disabled about 4 times yesterday driving down the A1 to Grantham and back. Snow was light to medium and it obviously built enough each time to block the sensor. Made me think why the hell is something like this not heated, especially given it's so close to the bloody engine!

It might well be heated but snow and low air temp plus wind blast would mean it would need to be very heated indeed to stop that I'd have thought!

I know for definite the old radar sensor is heated but I'm not sure about the new badge one.

It has happened twice to me, but it was whilst sitting in bumper to bumper traffic for over an hour each time. I just turned the car on and off for a second each time and it went away.

Sounds like its not permanently heated by only heats up on start then.... VCDS could probably fix that!

Anyone fancy the job?

I would think it's temperature related.
