Mercedes C36 AMG - Piston Rings Needed

[Braingears]

I desperately need help find rings for my C36 M104 engine. The VIN is
WDB HM36E4TF386984

The stamp on the Piston is
Mahle 91P16+ (89.90mm)

These are the rings that were in the engine (measured by my mechanic).
1.2 x 3.3
1.5 x 3.7
2.5 x 2.2

The dealer's part number through their chain of replacement numbers came up with
A 003 030 92 24
These rings are way too big for this piston and cannot be used.
1.50
1.75
3.00

Needless to say, I need help tracking down the correct rings for this engine. Please Help!
