Parking Help Unavailable Dash Message Fault

[Danm182]

You really need a proper diagnostic on it before replacing anything to ascertain the issue. Generic code readers won't cut the mustard on these.

I was hoping to find a quick, easy and cheap fix I could do myself never works that way for me! Hill assist seems temperamental as well, wonder if they are linked somehow?
I'll get an auto electrician have a go at it.
Thanks for your help

Hill start assist is controlled by the ESP system, so won't be affected by a parking assistance fault. That usually means there's an issue with a wheel speed sensor or other part of the ESP system if you are getting that warning - and also if there is a wheel speed sensor issue, I would expect other ESP warnings and disabling of things like the cruise control if fitted.

I still say you need to get it properly diagnosed, preferably with Diagbox to ensure any and all fault codes are picked up.

Hi, I've the same message on a Citroen relay 2017 plate which does have parking sensors but I'm not sure if they're factory fit or aftermarket (my van is a camper conversion I've just bought). My VIN is VF7**************[VIN obfuscated, can be read by forum staff]. Can someone please confirm whether the sensors are factory fit one?

Also, I've tried to reset the BSI which hasn't done anything as far as I can tell but how do you even know if you've actually completed the reset?

Thanks in advance

I had a similar issue with my Boxer. I had a length of lumber protruding from the cab and I was reversing. The alarm went wooly! Anyway, I went forward only and the "Parking Help Unavailable" and orange warning (!) was illuminated. It stayed on for about 6 miles - I was concerned. I stopped and restarted and the same message/warning light came on.

SOLUTION: I put the vehicle in reverse and then forward again - problem solved. I hope this makes sense.
