code 66 and boost issues..how to clean them out !!

1, remove top part of airbox with maf attached and set to one side. there is a round multi plug that is clipped onto the airbox that is best removed for ease of access.....



2, undo the three bolts that hold on the solenoid box, 2 on top which has an earth attached and one half way down which holds box to turret...





3, remove top bolt on top of box and remove slide that holds in the hose connectors...you can remove them one at a time...

4, remove the little breathers from the top of al the solenoids ( 4 of them) . **circled yellow in pics...**

5, connect the two sets of diagnostic spades under dash..green and black...turn on ignition but dont start...(fans will come on and the solenoids will all be clicking....) 

6, remove the hoses (inside box) from ONE solenoid at a time from both ends to where they connect. 



this is the one that usually gets dirty and the hose that attaches to this solenoid..


7, spray through with carb cleaner and then blow out excess. 

8, spray into the solenoid from the two bottom pipes for a second or three each....

9, connect the hoses back remembering where they came from. this is why its important to do only one at a time....

10, continue and do the rest the same way, one solenoid at a time. (there will only be two hoses to remove at a time to save confusion.....) 

11, replace all filter tops to solenoids and return box to turret and bolt down as you removed it...

12, do the same with the outside hoses that go to dump valves, intercooler and actuators etc one at a time also....

13, basically put everything back on that you removed which shouldnt be much really.

turn ignition off disconnect wires under dash....disconnect battery for ten minutes ...reconnect battery...take for a gentle drive and car should be fine.....connect black connectors under dash to check all is well..(codes should be gone and should steadily flash one per second ish) 

sounds a lot but isnt really....
