you can use diesel to flush the engine, ive done it myself and Siena has done it too...
My method was to drain the engine oil out, refill to the max line with derv and start the engine, (i then ran the engine at 2krpm for 10minutes, Siena's method seems to be to let it idle for most of the 10 minutes with short bursts up to 2k) do not load the engine up or attempt to drive the car in any way, just run it for the 10mins then shut it off and drain the derv out.
Refill with fresh oil and a new filter and run it for about 500miles, before changing it again. I would suggest cheaper oil for the 500miles after the flush.
Wether i'd do a flush like that on an S4 motor however is another story. Its quite aggressive, so you'd have to be pretty sure it needed it before doing it tbh! and i doubt magnatec in the engine for a short time would really cause any issues tbh, magnatec left in there for thousands of miles with neglected oil changes perhaps, but not just a top up for a few months imo.
I still think you should try to get a secondary guage on the engine, either instead of, or alongside the original guage and see what numbers you get from that
