Audi A4 8E: Engine Speed on Motor Control Unit

Hello.
Does anyone know where to find the engine speed data on the engine control unit (ECU)?
Comfort doesn't interest me.
An ID would be sufficient, although Bytes and conversion would also be great.

I found the following IDs:
00000050
000000C2
000001A0
00000280
00000288
00000320
00000380
0000038A
00000420
00000480
00000488
000004A0
000004A8
00000520
00000580
00000588
000005A0
000005D0
000005D2
000005D8
000005E0

The following data are being sought:
Water temperature: - found.
Oil temperature - found.
Speed - found.
Speed - currently searching.
On-board voltage - to do.
Boost pressure - to do.
Fuel tank level - to do.
Oil pressure - to do.

I would appreciate any information you have regarding IDs and MOTOR-Can.

Thank you.
