Problem: I can’t use VVDI Key Tool Plus to read VW med17.5.25 ecu, I get timeout error message, any ideas what could be wrong?
Look at the images below on the ECU info and error message:
Possible Reason and Solution:
- Probably bad protocol. Send Xhorse dumps from tuning tool and they can get you cs etc.
- Try with Ktag, with ktag you will need to open the ecu.
1) Reworked Ktag test report:
It is working with reworked Ktag, but sometimes you need read ECU like MED17.5.21
2) Clone Ktag report:
It worked for me. One friend use the diagram from MED17.5.25 but the protocol from MED17.5.21, so he reported not working.
- PCMFlash ori + module 71 test report:
PCMFlash ori + module 71 is tested working fine, but cost much more.
Good to know:
Bench Mode maybe Not possible because no tp20
You have to open it, have Same Last time
