Sapp, F. Gefangen in Stalingrad (1943 bis 1946). — Steyr: Ennsthaler, 1998. This satisfies your criteria completely, except that the soldier is Austrian.
Fritzsche K. Das Ziel - überleben: Sechs Jahre hinter Stacheldraht. — Zweibrücken VDM Heinz Nickel, 2002. This guy is German who spent 6 years in captivity, not a "simple soldier", but a pilot, leutenant.
Zieser B. The Road то Stalingrad. — New York: Ballantine Books, 1956. German soldier, captured in Stalingrad.

My mother's cousin's husband was one of the 5,000 survivors who were repatriated. While he lived into his 80s, he had emotional/psychological problems for the rest of his life. On the other hand, another cousin was one of the casualties of Stalingrad.

In 2002, I had the occasion to speak with a German Army survivor of Soviet POW captivity (my wife's godmother's husband). His rank was no higher than a non-com but I don't remember exactly what it was and he had served as a Pioneer.
When he learned I was an amateur blacksmith he related to me how he survived captivity by using smithing skills he had learned as an apprentice machinist. He told me the group of smiths he worked with had a quota of four axe heads per day. These were forged out of the cut up barrels of artillery pieces. However, the real quota was five axe heads since the guards took one to barter with the locals for vodka.
