FLYOBD SVCI 2020 “Target unit does not respond” Solution

About a year ago I bought a used SVCI 2020, everything worked fine, all functions until one day when you try to connect or use special functions after trying to connect you get the message: target device does not answer. Both CAN and K-Line do not work. While the key fob works perfectly, transponders and so on can be cloned.

Possible reason:

When You connect to the car that has the power supply only on OBD pin 16, than the SVCI will work for long time. But some cars have additional ignition supply, sometimes on pin 8, sometimes on pin 1. In other cars pin 1 or pin 8 is k-line for some modules. And there is no hardware protection that will disconnect signal lines when You connect the OBD to car with additional power supply. It can just fry the CPU inside and then it’s not connecting.

What to do next?

Check and replace 8pin voltage regulator on the backside of the pcb board near fuse. This is common issue with svci device and always no communication via can problem.

You can use mc33063 or mc34063:

Feedback:

Thanks for the info the SVCI 2020 is working again.

How to Solve VW Amarok Caddy 2018+ Remote Not Working After Programming

Here comes the general problem of VW Amarok Caddy etc. 2018+ UDS protocol vehicles: 2019 VW Caddy. I spent a few hours programming the Xhorse key using VVDI2 . Also tried TDB1000. Remote function could not be obtained. Every time the programming failed, the original remote stopped working until I scanned and cleared errors. I expected it to work when the transponder was added (Megamos AES). I can’t access remote learning with any of my tools, nor did vvdi2 let me program the remote. I was wondering if anyone could confirm remote learning with transponders or how to learn it if not. Solution: It is not possible for BH remote controls after 2018 at the latest. You will not get any communication with the central locking remote control customization. You need a dealer key 100% and then learn from ODIS. There is no after-market solution, VAG blocked the remote channel on UDS vehicles 2018+. Had the exact same issues with new caddies. So merchant key and Odis ATM since the c...
