E70 3.0sd multipe errors, reduced power

[mxxxs]

Hi,

I need urgent hep if anybody knows, I have a 2008 E70 3.0sd and while traveling, after 500km about, i got an oil sensor error on the board computer.
After a while I also got a increased emissions error. At that time I realized that the engine power was reduced, like not having turbos.
After performing a diag test with ista I got a lot of errors, a friend of mine suggested to look at the fuse box under the filter in the engine bay. A 20A (F2) fuse was burned I exchanged it but as soon as I started the engine the fuse was burned again.
Now the errors I have are:
004206 dde oxygen sensor recirculation controller activation
0046F6 dde wastegate valve, activation
0046D6 dde compressor bypass plate activation,
xx141 dde swirl flap activation,
xxx1D1 dde exhaust gas recirculation
xxx1D1 dde oxygen sensor heater activation


(for the last errors I can't see the error number in the photo).


I would appreciate if anybody could help me with any suggestion, cause I am abroad in a place that is no service shop near by.


Thanks
