Creaking sound on momentum change 99 RsFour

[Wazmond]

So everytime the car is changing momentum, say you were going forward, and then you brake, itll do the creaking  and then wont happen when you brake again while still going forward.
but once you put it into reverse and then you brake itll creak, but wont creak any more after while still reversing.
And then again, when you go back to forward and the first time you brake, itll creak.  ( note will only happen the first time you brake when traveling a direction ).
Wont happen, when youre going up speed bumps or hitting a pothole etc.

Sound comes from Front left area. 
 

I'm unsure as to what might be causing this sound so if anyone has any suggestions please. Ive got a set of R34 GTT brakes that I will be installing soon too. (and disregard the gutter rashes, from previous owner(s)... ) Otherwise, it has a shot set of Tein Coilovers, original bushings except poly on tension rods.
Car has 138k kms.

Grease the poly bushes as your first order of business. Moly grease.

Spanner check everything else.

Inspect LCA inner bushes.

You gave me another reason to avoid poly bushings 😂
