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:

Protocol: KWPS8FE9 ( it should be CAN protocol )
ECU Address(es): 1A

CAL ID: 02F300050D 1402

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

Consolidated Readiness: UUCUUUUURUUU
Supported Readiness: UUSUUUUURUUU

OBDII Readiness Monitor Details:
Misfire Monitor Supported: N
Fuel System Monitoring Supported: N
Component Monitor Supported: Y
Catalyst Monitor Supported: N
Heated Catalyst Supported: N
EVAP System Supported: N
Miss Monitor Ready: NS
Fuel System Monitor Ready: NS
Component Monitor Ready: NS
Catalyst Monitor Ready: NS
Heated Catalyst Monitor Ready: NS
EVAP Monitor Ready: NS

If you look at those monitors not supported and Is that why protocol
Id not matching instead CAN bus system ?

Any help would be appreciated.
