You are using detect protocol? It will report BUS INIT error on every protocol that is not supported by your vehicle. With VW and OBDLink adapter, I would recommend that leave the protocol to auto-detect. It should work very well in this pair of tech. ---

Use the ‘share’ button on OBD2 monitor to get the full text listing on what happens during the protocol detection and paste that here so I can take a closer look. ---

That’s odd. I have never heard before problems with VW cars of that era. Can you read data with other apps than RealDash? ---

Yes with other apps I can read many data but I just love the realdash and I hope we find a solution ---

Obdlink with respective app works fine but looses connection with realdash and I tried all sort of settings and results are the same. I borrowed a android phone to test it on android too but the same results. I have obdeleven too and I tried that too but obdeleven is working only with its own app Thanks ---

Only thing I can think of is that your vehicle needs a special initialization command which we are not aware of. If you find the command sequence needed for your vehicle to respond to the ‘0100’, we can then easily add that configuration to RealDash. ---

That would be great if we give it a go. Thanks a lot ---

Here is my car gateway information if it helps in any way Gatbwa^^ System description J533\_Gateway H04 Protocol TP2.0: KWP2000 Software number 1K0907530K Software version 0021 Hardware number 1K0907951 Hardware version Thank you very much ---

Protocol KWP2000 should be ISO 14230-4, which is protocol 4 on OBD2 adapter. Go to the OBD2 Monitor and try to give following commands: ```plaintext atd atz atsp4 atdpn 0100 ``` ---

Hi I tried the commands and here is the screenshot. Still intermittent connection and beside the RPM which keeps loosing data due to the fact the realdash is working intermittently. I hope one day realdash supports obdeleven. Thanks for the help ![4AC3700A-196E-4ED8-B0D4-31F62B911C79.png](https://forum.realdash.net/uploads/default/original/1X/b6ee5f56249ed178adc2c64be93efe95d97e4580.png) ---

So RealDash now connects to your vehicle and you can see the data on the dashboard? Could you explain in more detail what you mean by the ‘intermittent connection and beside the RPM which keeps loosing data’? ---

While I use realdash it’s disconnecting and reconnecting all the time. No turn signals No fuel level and so on ---

Send debug log and I will take a look why its disconnecting.
