Turbo overboost and checking oil level at rear differential

[Rein]

How do I check the oil or replace the oil in the rear differential on my Delta HF Integrale?

I believe I'm having some problems with my turbo; when accelerating fully i.e. 2nd gear, shifting to 3rd using full throttle and full turbo boost, the turbo kind of cuts all the power. I then then have to go off the pedal and start over again...

Could it be the throttle potentiometer of something like that? This only happens when having full turbo boost...
