Park assist no longer detects parking space. I think I have narrowed it down to Park assist control module. I have a used replacement. Is it plug and play or will it need to be programed. If so how. I hope I don't have to take it in to BMW. thanks. Oh,just remembered is there an easy way to get surround off luggage hook in boot so I can remove panel?

Welcome to the Forum

A diagnostic scan will confirm the issue so before spending your Hard Earned that would be my course of action. Either find a BMW specialist or a good independent garage that has BMW capable diagnostics (Foxwell, Autologic, iCarsoft) 

Or if you are a DIY fan then buy your own Google BMW Diagnostic Software for less than the cost of a single visit to a Dealer you could have your own.

Thanks for that Dave. I have a friend with a magic box but I don't think it's up to the job. I am taking your advice and will let main agents tell me exactly what's wrong. Thinking back I think it was OK untill a deer decided to hit my bumper.  The bumper etc was replaced. Maybe it needed resetting.  All will be revealed. The park assist is something I am afraid to use (probably twice in 28000miles)😆 but if it there I want it to work. What is the software I could get for future use. Thanks nigel

Damn Bambi 😅 we just don't eat enough Venison in the UK 😅 Totally agree with you if it's on the car it should work and it bugs me if it doesn't.

I brought my copy of BMW INPA/ISTA a long long time ago (can't remember where now) but a friend of our son brought a copy last year from www.djwwautodiagnostics.co.uk he paid £90 and it works really well (save him blocking my driveway while he uses mine 😅) The best software is BMW INPA/ISTA which will give you full Dealer level access to your car for diagnostics and repair information, it also contains Wiring diagrams and Workshop information 

Apparently the company are UK based and give full back up, though I personally have not used them but he is a happy bunny

Hope this helps
