ACC error
« on: 10 July 2015, 16:53 »
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).

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).

Whey ya bugger! It's finally arrived after an 8 month wait....

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.
