Title: Turbo underboost Wastgate and P2263
Post by: Markus667 on January 01, 2023, 12:44:37 pm

Hi Guys,
 Happy New Year everyone.
 I have a problem with my torbo.  I have the CX5 KE 2014 150 hp with the Garret two stage turbo.
First stage doesn’t work.
 According to the live data stream, the wastegate a is about 50% open from idle to 2500rpm.  From 2500 then the turbo boost starts again.
 And the wastgate supplies variable values up to 90 %
 I'm now wondering if the small turbo doesn't get boost pressure due to the open wastegate A.  Or is it controlled differently?
 If not, I'd like to review the Wastgate Actuator.  I noticed that the rod is loose.  But I don't know if it should be rigid when the engine is off.  Does anyone know if the wastgate is preloaded or how the correct pressure setting is?  Unfortunately I didn't find anything on Garret's website or on the internet.

 Regards

Markus

Solved the Problem. The Wastegate-Solanoid was damaged . Replaced it . Now turbo is running again.
