SOLVED

This turned out to have a very simple solution.  In the MMI CAR options there is a setting for tailgate.  With it on the external switch is disabled and you can only open it with the fob.  With it off the external switch is enabled.

Hope that helps someone else.

Hi Gareth

Thanks for getting back to me so quickly. 

I was interested in your theories so went out to try something.  I just popped the tailgate with the fob but didn't lift it, so it was literally 5mm from being closed.

If I squeeze the membrane switch the lock clicks.  I'll certainly look at it further but I don't think think we have the solution just yet ☹️

Cheers, Keith

Hi

I have just bought my 2008 A4 Avant B8 which has a few niggles.  Most of which I just have to go ahead and fix but this one is strange.

I do a general unlock of the car with the key fob but am unable to open the tailgate manually by just squeezing the membrane (between the number plate and the rings)

I CAN pop the tailgate using the boot opening button on the fob.  If I then close the tailgate again I cant open it manually.  The membrane switch seems unresponsive (no clicks or anything)

However if I press the membrane switch when the tailgate is open I can hear the lock click.  In fact if I manually close the lock with the tailgate open and then press the membrane switch it pops open again.

So why doesn't it work when the tailgate is shut???????  I have never had one of these cars before so perhaps I am missing something obvious.

Thanks, Keith.
