Automotive calculate the CRC8

[electronic_lab]

Hello, I have been analyzing some CAN ID, and I found one that has a CRC8 acording to my dbc. The last byte is the CRC8, but I don't know how is calculated. The first byte (byte 0) is a CHK which is The XOR of the rest of bytes + 134. 134 is the ID. I would like to find out what is the formula for the CRC.

The message of the dbc is: 

F r MLB:
'Berechnung siehe Lastenheft 'Kommunikationsabsicherung f r FlexRay und CAN''

Ab MQB und MLBevo:
'Berechnung siehe Lastenheft 'End-to-End Kommunikationsabsicherung'

Endwerte siehe Begleitdokument 'S-PDU Kennungsfolgen

which means:

For MLB:
'Calculation see specification 'Communication security for FlexRay and CAN''

From MQB and MLBevo:
'Calculation see specification 'End-to-End communication security'

End values ​​see accompanying document 'S-PDU identification sequences

You write down the formula (XOR all bytes except first one and add 134) and then you ask for the formula in the next sentence???
