Bosch 074 906 021 L 0 281 001 immo off

Hi all can someone help I have a Vw caravelle Tdi here year 1998 I would like to immo off this ecu ? I have opened the ecu and found some EPROMs which one contains the immo data? I think it should be 24c02 Can it be read in circuit or not?


I have tryed reading with Kess(unknown ecu) , mpps 13 (get I'd but won't read)and mpps 18 (get I'd but won't read) Also have tryed VVDI 2 and AVDI orig all no go!
