Hi, unfortunately last night I hit a pheasant and this morning I found that it had hit the acc sensor perfectly and thought I had lost the lot, but found the sensor still attached but layed on the lower spoiler. Has anyone had this happen to them and can advise the best way forward? Can you buy the housing from vw and then get it set up by them? Also the stop/start is showing error this morning, never done this before could it be connected. I disconnected the acc sensor unit so I could keep it safe, I didn't want to lose it. Any help would be greatly appreciated,

I believe the auto-stop start uses that sensor to detect the moving traffic so yes pulling the sensor out would affect it. You will need to get the sensor refitted and re-calibrated properly. I think it needs to know where dead centre is so that it knows it is looking in the right direction.

Yes you can buy the housing (trim piece) for the radar sensor be it the original round shaped sensor or the later square shaped sensor. You are talking about just a few pounds.
The trouble is that the cost of recalibrating the sensor, if it needs to be done, is not cheap.
-
VW Dealer in Lincoln quoted me £150 to calibrate sensor. I just hope that your sensor is undamaged...
-
Thanks for the replies, it's the square shaped sensor and doesn't look to be damaged, I hope. I'll take a trip to the dealer and price some parts and calibration

It happened to me twice, the first time was about 2 years ago on my 2014 GTI, luckly it only knocked the ACC radar housing out of place and I could find it inside the bumper, rattling on the plastic undertray. 3 of the 4 plastic clips that hold it in place were broken but I managed to glue it to the sensor and it worked like that just fine. The second time it happened on the 2016 GTI just a few weeks ago, unfortunately this time the pheasant was pretty big and it f***ed my lower honeycomb grille, the ACC radar housing and two plastic bits from inside the bumper that cover the AC pipes and the left side of the radiator. The pheasant was literally split in half, I spent 1 hour to pull out all the feathers and guts from inside the bumper.
Result: The radar housing was completely gone, couldn't find it in the bumper like the first time, the grille and the plastic bits inside on the radiator where all cracked and broken and the radar sensor itself was out of it's normal position (it has 3 plastic fixing points held in place with 3 bolts which are also used for calibration). The sensor itself was undamaged although I had the Front assist disabled error message on the MFD and the ACC was not working at all. When scanning with VCDS it showed 2 error codes relating to incorrect position of the sensor. I just wiggled it back into the 3 fixing points, it's literally a matter of pushing the sensor back in place and the error was gone after driving 10 miles and the ACC works again.
The housing is pretty cheap, around £5 quid, the part number for GTI/GTD is 5G0 907 225 A 9B9. You can order from any dealer or you can find it on ebay for around £8 as well.
Apart from this I had to order new honeycomb lower grille which was around £35 and the plastic bits inside the bumper were around £12. All in all it cost me £51 in parts. The labour was free as I took the bumper off and swapped the damaged grile and parts myself.

Thanks, I've been to the dealer and ordered the cover and the housing which came to £30 but they said the recalibration would be about £400 ! I think I need to phone round some dealers, it's a shame Lincolns so far, can independent garages align the sensor?
-
£400. That's insane. It certainly wouldn't hurt to call around some independents.

wow! £150 suddenly doesn't seem so bad! If you're in Yorkshire its maybe not that far...
-
Just googled it and Lincolns 85 miles away, so may be worth a day out. While googling stuff came across some one who reckoned he'd realigned it with a laser level! May be worth a try, how hard can it be :smiley:
-
Any luck with laser level?
Mine's got incorrect position error as well (according to VW dealer hit by road debris and they replaced mount).
-
Didn't need to use it in the end, as the sensor clipped back into its mount which wasn't broke, and pulled back into position. All seems to be working ok so I think I've been very lucky. I've got a brand new mounting kit if anybody needs one!
-
Too late now, dealer fitted it to mine.
Although feels all very dodgy to me. They say they looked at ACC sensor due to fault code, I scanned it a week before and no ACC faults. No signs of any impact on front of the car either. Sensor itself was not changed either, nor the shroud around it..... nothing looks like they had a knock. If it wasn't a company car I'd go up the walls as they want money for it (and at the same time reject to change the scored crap they use as rear brakes on a 6 months old car).
