Well I had the car in to Benfield on a "while you wait" basis for the recent ACC "unavailable" faults that have happened 7 times that I recall.
2 different stories:-
1. Technician comes out and say there are 8 separate logs of ACC fault associated with what the computer thinks is an obstructed view. He says there've been a few other examples of this fault and the ACC system has been replaced, getting rid of the fault. I told him that every time i've been aware of it, the car has been on a long and sweeping bend at around 30mph, suggesting that the car had nothing to lock onto in front of it, and maybe there was some implausibility factor involved because of it. He said it was a possibility. I also said that since it cooled down a little this week then it hasn't happened, but as the sensor is low down in the grille out of glare and will have lots of cold air rushing over it, I don't think it's that.
I also mentioned that quite often the ACC system doesn't flag up that <>!<> symbol (2 cars with an exclamation mark in between) at times where I know the GTD would've done, and i've only had one false positive to warn me to brake since I have had the car (would've been more than that on the GTD). With all that in mind, I think that either the ACC sensor is faulty (likely) or it hasn't been set up correctly. I say to him that the car is only 6 weeks old tomorrow, you can clearly see that it hasn't been hit at all and the ACC unit doesn't look as though it has taken a hit either. While the car is in, I mention the unsightly gaps where the black side spoilers meet the main spoiler on the back.
2. His manager comes out to hand me back the keys half an hour later, telling me that the ACC will get recalibrated, but it's not warranty, it's goodwill. I ask why it's goodwill when the car, and the ACC sensor in particular, is completely free of damage. He squirmed a bit and I asked whether they'd honestly take on half a day's worth of unpaid work as goodwill when the car wasn't even bought from Benfield. He didn't really reply to that question - why make out they're doing me a huge favour, it's a warranty job - I know it and he knows it. They're going to treat my spoiler gaps like the recent warranty work for a lot of cars (even though mine isn't part of the hit list) - whoever is placing them at the factory clearly hasn't improved!
He did ask why Benfield couldn't help in sourcing me a car when I placed the order - so I told him that being short changed on the p/x by almost a grand and not getting 1/2 the discount I got from Pulman I was about £2800 better off going there. He said they're seeing that quite a bit lately!
So the car is in next Friday morning provisionally - assuming I can have the time off as a 1/2 day's holiday (I would have to wait 3 weeks for a courtesy car).
-
Book it in to Pulman and get them to drop you at work.

I would Chris, but i'm at work for 7am, Pulman don't open until 8, and if i get an almost immediate lift to work, it will still be 8:30 unitil I get there. I only have to take a half day to get Friday off (we work an extra hour Monday to Thurs to get away 3 hours early on a Friday - so they gain an hour out of us, but it means I only have to put in 4.5 days to have a week off, or 1/2 a day to get Friday off). I'll be happy to take the 1/2 day if the car gets fixed and my time hasn't been wasted.
I'm just puzzled as to why they wouldn't replace the sensor that has thrown up faults when there's nothing to suggest it has been mounted and calibrated incorrectly, when labour makes up the majority of the cost of the work (the sensor itself is quite cheap I believe). The manager's talk seemed to contradict what the technician said. If the sensor is faulty then it's a warranty job to replace and calibrate. If the sensor is not faulty and shows no signs to taking a hit then it has been set up wrong at the factory and would still be a warranty job (assuming that the PDI doesn't involve calibration of the ACC system and it's done in the factory).
-
Pulman Durham open at 7.30am and I'd still take it in to then rather to the pri4ks at benfield. Remember what they did to your gtd. If you're taking a half day then drive up to Durham.

That'll be 1/2 a day plus other time if they want to diagnose one day and order a new sensor in the next. I'll give Benfield this one chance and show them that the car is as clean as a whistle when passed to them.
Not sure how Durham Pulman are sorted at the moment as the sales team were operating out of a wedding sized gazebo when I picked up my R - didn't see what facilities the service dept were operating from (presumably not another Gazebo round the back!).

Somebody posted a while back the sensor itself is £926.10 inc vat without installation/calibration.
Perhaps someone can confirm this ?

I was convinced i'd read somewhere that it was an £80ish unit and about £400 to calibrate it.

Funny the same post said it costs £1330 including fitting / calibration which is why I made a note at the time - very expensive if you ever did clout it I thought at the time.
I realise this is not what has happened with your current situation.

That's a lot of money - i'm sure people would shy away from repairing a faulty one out of warranty. As they become more commonplace as standard equipment/cheap option i'd expect the price to come right down- it's old tech used in a new way and doesn't seem as though it should be too expensive to make.
Mine has not been touched - I checked and made sure I hadn't been a victim of some clumsy bugger with a towing eye. As useful as ACC is, I would be loathed to pay silly money for one as an option if it didn't come as standard. It's a £500 option on a Polo.

Pulman service are inside still matt and everything is fine. It's only the sales lads who are in the tent.

A girl at my work bought a nearly new Mk7 GT. She has had a lot of problems with her car. It turns out it was the ACC. The strange thing is the errors were not recorded by car. She did not buy locally and every time she took it to the dealer she bought it from, they could not find an error. I think she said 4 visits 70-80 miles away. So she started taking it to her local dealer when the error happened. Eventually, they detected an ACC error and said the unit was faulty and needed replaced. However, they said that they could not do it under warranty as the car was not bought there! So the matter is now with VW UK. As the car is still under warranty.
This all seems very strange. Does anyone know if the ECU can be set with the VCDS not to record errors?
-
Every instance of error was recorded, and in each case it was as though the sensor's field of view was obscured.
The local dealership were saying it isn't a warranty job, but the fact they confirmed it hadn't been working at multiple times and it has no physical damage says it is faulty or wasn't calibrated properly.
The rival dealership group to where I bought the car is closer to home and they're going to do a "non-warranty job" out of their own pocket to calibrate it seems ridiculously generous to me.
Seems that fixing the ACC unit to maintain proper operation of it is a warranty minefield.

I've had some issues with ACC on my GTi although it is working properly currently, and both times I have been to different dealers they have said that any work wont be covered by warranty as the device needs all 4 wheels to be in perfect alignment and if it is not (and with the state of the roads that is unlikely) it becomes wear and tear not warranty....
No matter what I said they were not moving on that point so i told them its my last VW and I'd be going back to BMW.... and needless to say, it wont be getting fixed before it is part ex'd (although it seems to have fixed itself to help the dealers out!)

My warning came up again, same place as it has happened 2/3 of the time - exiting the Tyne Tunnel Northbound - a long sweeping left bend, around 1/2 a mile long. Will be interesting to see if Benfield manage to fix it with their "goodwill" on Friday as my holiday from work has been approved.
Mine has not worked properly since day 1 - the lack of <car>!<car> warning when tailgating other cars and lack of false alerts compared to the GTD is the giveaway.
I don't make a habit of tailgating as I try to avoid stone chip, but suspecting it wasn't working properly, I have tried to instigate the warning.
If VW can avoid fixing an item on the car that isn't working properly, without demonstrating misuse like kerbed wheels that could cause wheel misalignment then what else can they wriggle out of?
I suspect that isleaiw's dealership is one of these ultra-cautious outfits that is in perpetual fear of doing work VW won't reimburse them for, usually without foundation. Had a similar issue years ago when Benfield wouldn't touch whitewormed alloys even though there was no scuffing or chipping - Pulman replaced them straight away.

I suspect that you are right - although two different dealerships that belong to different national chains (JCT and Vertu) would suggest its a theme rather than a one off. My brother is a service manager and has grown up at main dealer franchises and he said he would have sorted it and claimed unless there was a specific reason (like a bulletin or prior irrecoverability) to suggest otherwise

Matt,
You sure this feature is turned on? I deactivated mine in my GTD, think it was in the MFD menus, something to do with ACC, can't remember off the top of my head. Wondering if maybe yours has been turned off by the dealer and that is why you're not getting the logo?

Kyle,
Definitely switched on. I sometimes get the <car>!<car> and red alerts, but probably 1/4 of the time I would've done in the GTD when driving the same way. I have tried narrowing and extending the intervention distance but it makes no odds. The warning to say the ACC sensor wasn't working yet again on the way home - long sweeping bend and low speed.
-
I have never had that warning, or anything similar in my GTI either. I frequently get the tailgating sign, but then I live in Northern Ireland, where we have, quite possibly, the worst drivers in the world. No one seems to realise that Lane 2 is purely for overtaking and you will quite often find someone sitting there, despite there being nothing else for miles around. When you do approach from behind, all that seems to happen is that they slow down. <rolls-eyes>
No-one seems to know that they have an indicator either and if you are following, the only sign that they are about to turn is a gradual loss of speed with engine braking, followed by a last-minute flicker of the brake-lights, then a bit of a veer in the opposite direction to an anticipated turn, finalised by sudden opposite lock into said turning. :angry:

On my way to my client today, through some 50mph average speed camera motorway roadworks, ACC on...... I get a BONG, followed by an orange cruise control light on the MFD and the message "ACC: no clear view" and "ACC deactivated".
What did I think the problem was?
A road sweeper had pulled out of the site entrance, in front of me, did several hundred metres, screwed my ACC up, then drove into the roadworks and disappeared.
About 2 minutes later, error light goes out, ACC is fine.
I keep saying its jamming and its definitely some sort of radar unit on those road sweepers...
-
Hopefully i'll get my fix tomorrow morning - and hopefully the car will see what's in front of it a little more often and not throw up that error. The error came up again tonight, well after i'd passed the toll barrier at the Tyne tunnel.

Interesting post this. Mine has started doing this quite a lot recently having had 2 years of trouble free cruise control. I drove to London and back last night on the M1 and got it both ways - both times in 50mph average speed roadworks (where you most need the damned cruise control).
I get the ACC No sensor view message and ACC Deactivated. Needs to go back in the dealers, but my dealers is one of those where as long as the ACC works on the 1 mile dual carriageway there must be no fault, and proceed to delete all the fault codes.
After an indeterminate number of minuts (5 or so) it always comes back.
-
I've been getting the same errors on the ACC as others. Been happening for the last 6 months or so. Bloody pain!
What's odd is that the fault disappears when you switch the ignition on and off again. Not very convenient when using the system on the motorway in a 50 mph average speed camera zone.
The fault is so intermittent I'm not going to take to the dealers unless the fail frequency increases. At present I can go months with out the ACC error occurring.
Darn gremlins :angry:
-
I never had this fault - maybe because roadwords in parts of motorway I use don't have metal barriers left an right......
There can be reflections in narrow lanes that throw the system off. Especially in heavier traffic (where you'd want to use ACC especially if you have a DSG box).
-
I would go back to the dealer you bought it from just incase its an on going problem and you have to reject the car...then they have all the history in house.
-
I had an ACC fault pop up about a year a go, which coincided with me going over a HBB a bit too quickly :whistle: & also a large leaf stuck over the sensor.
I therefore can't be 100% which occurence triggered the warning, but my local VW dealer found no faults, & it has never reappeared since.
-
ps. There is a 2013 GTI down my road with red calipers, but no ACC sensor in the front grill.
Does anybody know if this would be a non-PP GTI with painted calipers, or was the ACC not standard on earlier cars, because I didn't spec. this feature with my car, it just came with it? :undecided:
-
Possibly an Irish model as 2013/2014 models were woefully underspecced.
Spec improved from late 2014

Probably a 'Launch model' which had pretty much all the same features as the later ones but no adaptive cruise.

I had a very similar thing for the first time today going through a 50mph camera zone on the motorway, I use the speed limiter. The car in front of me was going really slow and eventually pulled in, as I got close I got the bong message about ACC no field of view, 30 seconds later it was working again, I even tested the ACC and it was fine. It was drizzling at the time though on a window bridge, maybe a chain of events caused it??? I'm not sure but will be keeping and eye on it!

There's no jamming going on...
I've seen the same in poor weather conditions e.g. snow/freezing conditions... with no roadsweepers. The roadsweeper probably coated the sensor in crud. Once the crud was washed off/ blown away, ACC was able to function again.
I did notice the other day when the local plod were doing a speed check in a village, ACC turned off (no warning) :undecided:
