Obviously I've never heard of this, is it someone you experts know? In Cheltenham.
Sounds pretty scary to drive TBH but I admire the determination to deliver something like that.

Sorry, being an unobservant dimwit, looking inside the engine bay!
This is it very obviously:

Thanks MJ, where is that exactly, or would a garage know where to look?
And what if anything needs removing to comfortably get at it?

Next question from the untrained - where is the fill port and what needs to be removed to get at it?

Edit: Looking around I found something that "might" be it under the scuttle panel between the air intake box and ECU box.
Looks really awkward to get at though, or is there a trick to it?

Is this ...

That sounds very familiar, thanks.

You just don't notice until the weather gets hot! :oops:
I suspect that at the very least it needs a re-gas, the last time it had that was at A8parts several years ago during an annual meet! It took quite a while...

But what specific guidance do I need in terms of where to get this done and what ...

Its usually the boot lock which causes the pump to run on Sure is! Thanks MJ. :mrgreen:
Misbehaving today and clamping the pipe to the boot lid IMMEDIATELY stops the pump. I do love a clear/consistent symptom. :lol:

As noted above some "noises" from the mechanism, sort of "poorly-lubricated ...

Strange, all working normally for several weeks until yesterday when unlocking I could hear the pump running for far too long again.
Sod's law, I was going to pick SWMBO up from the station so no time to investigate and by the time I did all was working normally. :?

From now on every time I go to ...

Thanks MJ, that's very useful :ugeek: Just had a quick play and it's the soft pipe on the left side.
If I pinch that hard the lock doesn't move while pressing the remote buttons but does immediately if I then release it, so there's no big leak.
Operating the system with the boot open I can hear ...

Thanks, though I don't know enough about how it works in detail to start looking for symptoms/issues.
I know there's an air pump, but is it increased or decreased air pressure or both?
e.g. I can envisage two pipes to each lock, one for open, one for lock OR a single pipe with blow for open and suck ...
