V50 Electrics : Park Assist not working

[shaneypoopers]

Hi,

Have a kind of a weird one, just got a 2012 V50 1.6d SE for my wife, all pretty good with it except that the park assist is not working.

When you put it into reverse the Infotainment system says that the system is engaged but the audio volume doesn't drop and there are no beeps.

I have checked each sensor for ticking/vibrating and none of them seem to be working, have taken the plugs off the control module and put them back on with nil fix, the car isn't displaying any fault with the system but obviously it is not working. The fuse is I think #69 and I have checked this is ok, also I would expect to get an error message if it were the fuse.

Has anyone run into this problem before? Is it likely that all four sensors would fail? Just looking for a bit of background/advice before I take the bumper off.

Thanks,

Shane

If you've only just got it and it's from a dealer/used car place, I would take it back and demand that they sort it.

Failing that, first check that the reversing lights come on when you put it in reverse - if not, it's probably a problem with the reverse switch.


If the reverse lights come on, have a double check that park assist has not been deactivated via the centre console menu. If it is activated or there isn't a setting to deactivate them, you'll need to get a multimeter and trace the wiring back to see exactly where the hold up is.

Thanks for the quick reply.

Bought it private unfortunately, did check the system on the test drive and when it activated thought all was good, didn't actually try reverse up to a wall!

The reverse lights all come on ok. Judging by the insulation tape I am seeing around the looms I am guessing this was done at the dealership before the car was originally sold.

Was hoping that there was some quick fix that I was missing but it looks like the bumper will have to come off, or the wife could learn how to reverse....bumper off.
