Hej !

P1549, Charge Air, Malfunction

Here is a quick guide, that may help.

a) Check the hoses to the charge air control valve.
If OK, go to "b"
b) Connect W and C, boost should never go above 0.50 bar.
If OK replace the control valve.
If not OK, check turbocharger

Default More error codes

Hey guys, I found this post and was hoping for some help.

I am working on my uncle's 2000 Saab 9-3 SE convertible and it comes up with the P1549 code as well as a P0106 and a P1300. The 1300 code came up initially when he brought it to me with running issues, but the turbo hoses had blown off/loose at some point as well. Ideas? thanks.
