Multiple Unrelated OBD Codes
2009 A4 2.0 Quattro
CEL suddenly on and throwing 10 codes that don't seem related. Any idea on what could be a common issue here? I cleared them once and they all came back immediately. I do not notice any drive-ability issues. Here they are:

Thought I'd post an update and experience since.
Turned out to be a blown fuse in the underhood tray by the ECU. I've attached a photo of the offending fuse. I took it in and the tech did a thorough look over. He had some concerns that it may be related to engine mounts but in the end just replaced the fuse. The car drove well for a few months then this past weekend the CEL came back on and the car is gutless.
The fuse was blown again so I replaced it and reset the codes.
The CEL has not come on again, but the car still has no power, like the turbo is not functioning.
Does anyone have a diagram of this fusebox? I can't find one online and would like to know what systems these are for. Any ideas on the problem of no power would be appreciated before I take it back to the dealer for a check.
