The only MAN engine I can think of with a power rating of 820hp was the very last mechanical V10. After that, on the V10 block, they built the electronic (non-CR) 1050hp first, and the 1100hp (CR) a couple of years later, before eventually phasing out the V10 altogether. If it's indeed the 820 V10 that you have got, to my knowledge it didn't come with any EGT sensors. Did you possibly retrofit them? If so, I'd be interested to hear any technical details you might have about that job - thanks in advance!
