Ah, you have the stiff suspension. Ours has the standard, as a result the suspension moves much more.
That said, every demo golf 7 I've had from the dealer has cracked and creaked from the front suspension bushes, so I'd bet I can make yours do it too.. particularly in winter as it's colder.
Pity VW does not agree and states it's normal and chooses to do nothing about it at all. Actually they drove out car with the ARB completely disconnected and it still does it. It's worse when you're braking and the suspension moves; therefore it seems to be the wishbone bush.
Top mounts and shocks have all been done. I'm sure it's the WB bushes. The b'stards refuse to admit they have a problem, yet every car in the fleet does it.
