2009 Volkswagen Jetta TDi 2.0L Diesel

Post by Alex48 »

I have 2009 Volkswagen Jetta TDI diesel 2.0L, they saying this car required CAN bus system instead kwp2000.

How does the protocol Id change? Maybe ECU is defective? Some people told me that OBD2 talking with different module from ECU.

from the car:

Protocol: KWPS8FE9 ( should be CAN )
ECU Address(es): 1A
CAL ID(Calibration ID): 02F300050D 1402 ( they say wrong CAL ID )
CAL CVN(Calibration Verification Number): 21DB ( they say wrong CAL CVN )

How is it possible ECU unit created not belong to this vehicle CAL ID (Calibration ID): 02F300050D 1402 and CAL CVN (Calibration Verification Number): 21DB ?

Could it miscommunicate protocol KWP instead of CAN protocol ?

If you look at those monitors not supported.

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

why is that obd test showing all monitors None or None Support ?

How is it possible ECU unit created not belong to this vehicle CAL ID (Calibration ID): 02F300050D 1402 and CAL CVN (Calibration Verification Number): 21DB ?

Could it miscommunicate protocol KWP instead of CAN protocol ?

any help would be appreciated.

Not sure if you're talking about direct CAN broadcast, or OBDII. We have a couple of guide here:

Hope this helps!
