bad heater control valve, how to be certain?

[bmwdirtracer]

Charge pressure control, pressure too low

(Sorry, had to use Google translate)

Step 1: Smoke test the intake system
Step 2: CLOSELY inspect all the vacuum lines
Step 3: Use a hand operated vacuum pump to test the wastegates

and, well, lets not talk about how much a new pair of turbos cost, installed.

Hey Chris,

I have the same symptoms as Mry82 mentioned above. I used INPA and got code 25 auxiliary water pump short to ground and tried clearing but it won't go away. Will this cause the same issues thst mry82 had? Thanks in advance.

I´m a little worried about Chris. He has not been online since the 17th. I know him personally and emailed as well, a couple weeks ago, and I have not heard back. I wonder if anyone know if he is okay?
