Allegedly spraying brake cleaner into the pipes works (never done it myself though).

Drivers side suspension turret.

 

sound mate thats great

 

works for a bit then it starts all over again just replace it

 

If you want to clean it, you need to put the car into test mode (do a search) and you'll hear it clicking. The best way I found is to remove the actual boost solenoid and its pipework but still leave it plugged in electrically, over a washing up bowl or something in the engine bay. Then start spraying brake or carb cleaner through it in every direction and you'll be amazed at how much oil residue is in there.
