Hey guys, new here.

Have a 335i 2007 E92 and there's no boost at all. Vacuum lines are already checked, selenoids are working, diverter valves are working as well, we've changed wastegate actuators and flaps, but there's still no boost.

What else can we look into?

Best regards

Any codes present? Tuning devices? Checked all the intercooler, hot and cold side charge pipes connections?

You said you replaced wastegate parts, did you inspect the turbos to ensure they are ok? Can we see a log?
