Hey All. I have a no boost issue with my 2010 JCW R56. I have smoke checked the entire system and everything is tight. I have replaced my DV and my Wastegate Boost Solenoid. I still do not have any boost. I am looking for other things I need to check that could be the cause of no boost. My turbo spins freely and does go up to 4psi at WOT. Normal driving the boost sits at -3 to -11PSI. There are no codes and aside from not having any boost, the car drives perfectly. I am at a complete loss, thinking it could be my wastegate?? Any advice is hugely appreciated.

Thanx!!

 

Maybe this will help.

 

I appreciate you posting those, unfortunately I’ve been through all those checks. I even used little zip ties to secure my vacuum lines. I replaced the vacuum solenoid and checked the tank for leaks. The only thing I haven’t replaced is the actual vacuum lines.

I’m worried that it’s the wastegate..

 

Does this help?

 

I suppose if I have the turbo completely off the car these are helpful. I need to figure out how to evaluate the turbo and wastegate with it on the car. I really do not want to tear the entire front off the car just to test my turbo if I can avoid it.
