Plug the two ends circled in red back together.
Then find the hose that goes to the solenoid and clamp the end of it and secure it somewhere where it won't melt.

I bought catless exhaust and dawes dewices. When I installed exhaust, the iddle run is very poor and sometimes engine switched off. Because my bleed (from digit power) doesn work with exhaust (pressure 1,6 bar) I bought dawes devices (racing version). I must cut some pipes. On the photo you will se which pipes. But problem with iddling is now bigger (on the 1200 rpm engine runs very well). Somebody told me that some of the pipe is especially for idling. I dont know but im sure that i didnt mistake........, because dawes has two ends and standard piping has 3 ends (to solenoid etc. My instalation is here. Please need help, my travelling through the city is bloody nightmare.........

Sorry I dont understand properly. Right circle is pipe from solenoid. But second solenoid end is now open/free because dawes has only two ends and is connected direct from turbo hose to actuator.
I cant do piping like standard. I missed one pipe.
Please hand made technical drawing?
Can these piping destroy engine or no? I see black smoke on idle.......

The pipe is FROM the solenoid and will give you a vacuum leak on idle so it will be crap. The one you are capping off is the one with the T-piece that went where the Dawes was.
So reconnect the ones I suggested, then find the other hose that goes to the other side of the solenoid and cap that off.

Thank you very much. I think that problems appeared after exhaust and before dawes instalation. (after dawes it was more bad) Have you any idea? Exhaust is only 3 inch pipe from start to end........ :-)

Take the Dawes off and put back the standard boost control (pipes as they were as standard) and go from there (don't put bleed valve back on, put it back to standard, as the car came from the factory).
If you still have an idle problem then it may be worth checking that the Blow Off Valve/Dump Valve is not leaking, that there are no other pipes leaking and failing that, see if you can get the car on a Select Monitor to check that the Lambda Sensor and the MAF are working ok and that there are no reported fault codes from the ECU.
Hope this helps,
Matt

Lambda works properly (i think). I have lambda link.... From 1500 rpms to end the engine runs very well. Maybe the senzor (luftmesser) after KN filter insertion is dirty. I will try..
Thanks
