My wife opened the boot on her Allroad as normal this morning and went to shut it and it wouldn't shut. The hook thingy thats on a spring is out to accept the closing bar but it doesn't catch/lock closed. I tried WD40 on it!!! Also, when you pull the lever to open it you can hear the electric mechanism working. The dash says the boot is open and it still locks all the doors... the boot is just loose like the mechanism isn't there. Any ideas?
