DS3 1.6 THP Boost Pressure Valve Location

I was just wondering where the boost pressure valve is located on the 1.6 THP. And are these a sealed unit or like the Astra 1.9 you are able to clean them.

It's the black box with the cable coming forward, bolted directly onto the right of the turbo.

What exactly do you mean by boost pressure valve? The diverter valve which Nomgle has kindly provided a pic for its location or the electro valve under the intake manifold that controls the waste gate actuator that controls the boost level by the amount of air the actual waste gate flapper valve allows to bypass the turbo?

The second one, electro valve.

Under manifold just follow the vacuum line back from the waste gate actuator. Of coarse have to pull off air filter housing and pipework to get down there.
