Vacuum Solenoid
I am getting a 30FF on acceleration on my 2010 535i N54. Doing a vacuum test on the solenoids this is what I am getting:
- Right solenoid: 9 Hg steady
- Left solenoid: instantly raises to 15 Hg makes a pop sound (I believe it is the wastegate) and then drops to 7 Hg
Can someone give me advice as to what is going on. I am getting 15 Hg out of the manifold and 22 Hg from the vacuum canisters.

This is with new solenoids and a newly installed ER chargepipe with Forge DV.
