E53 4.4 Valvetronic Control Module location?
 

I've been having intermittent problems with a few bad alternators. I got that sorted, but I've had the car stuck in engine fail safe as I'm getting a bad power supply signal to both VVT controllers via diagnostic.

This tells me that either the fuses have shot that are connected through the connector block, or a connection was jostled loose. I've seen where the control module is in the e39, inside the false firewall under the cabin filter, does anyone know the physical location of the VVT control module and power distribution box with fuses is in the e53 4.4?

Thanks in advance.
