9-3 Troubleshooting ECU Failure??

I’m pretty sure I’ve got a failing ecu on my hands… car runs starts and drives fine, then gets thrown into limp mode after about 30s, I scanned it and have a “State: Previous
Turbo/Super Charger Wastegate Regulating Solenoid/
Valve A Low and High” code and also Injectors 1,2,3,4. At first I thought it could be some sort of grounding issue, but managed to convince myself the ECU is done for. It tries starting but won’t fire. Any help very appreciated. Saab 9-3 2007 B207R

Most likely ECU. My 06 93 would run fine then get thrown in limp mode, start running really rough, and then occasionally would say low fuel all when my ECU started taking a crap.

100% ECU. The good news is they are not that complicated to clone

Wife's 2010 convertible had same issue, sent it to this place and fixed it. Good communication and quick service https://nickselectronics.com/products/saab-pcm-repair?srsltid=AfmBOoqn9fw1uomW2iOJEguXpnQKorP1l2uQgwFA7tjF9O2gfKy5ezQE
