f25 n52 msv90 burning fuse f02
hello, have a car with the very strange issue, keeps blowing F02 fuse in DME in the integrated supply module which causes no start engine.
According to newtis f02 responsible for 15n2 terminal.
we have no faults at all, we have exchanged engine ecu, not helped.
replaced both disa actuators in intake, this helped for 2 weeks, now again keep blowing the fuse.
With blown fuse engine work, it's causing only no crank, any hints?

This is common issue on these msv90. I have repaired many. The capacitors leak fluid and damage the pcb traces. If you open the ecu you will see. But be very careful when separating the board from the bottom half. I tends to flex and cause whole lot of other issues later.. good luck..
