I have 2009 Volkswagen Jetta TDI diesel, they saying this car require
CAN bus system instead kwp2000 (KWPS8FE9) My car showing on scanner.

My question for you guys;
How does the protocol Id change ?
maybe ECU computer defective? some people told me that OBD2 talking
with different module from ECU ? Because of aftermarket radio changed ?

from the car:

CAL CVN: 21DB

Bus Voltage: 13.50
PID Count(s): 9
DTC Count from Mode $01: 0

Consolidated Readiness: UUCUUUUURUUU
Supported Readiness: UUSUUUUURUUU

OBDII Readiness Monitor Details:

Miss Monitor Ready: NS
Fuel System Monitor Ready: NS

If you look at those monitors not supported and Is that why protocol
