Default W177 M260 Installation - 06-18-2022, 09:01 AM

Hi all, new to this forum though not a new JB4 user.

Hope this has not already been covered somewhere else, but I am really not finding much available information online wrt JB4 install for the 2018 A250 (W177/M260) so hoping to get some help here.

1) As per attached images, I have installed the sensor connectors A and B as highlighted; and left the FP connector unattached. The OBDII port has also been successfully connected and Bluetooth handshake working well.
2) However, I am getting several engine fault codes (attached image) that I am unable to erase (it appears immediatel after “Delete Code” has been activated via the app).
3) In addition, whilst I seem able to change the map and see live RPM, IAT, AFR, IGN an MAP data via the app, I am unable to see the Gear data.
4) On my car display, the boost is also showing a constant 1.2kPa instead of the regular variable boost values without the JB4.

I am hoping that this is a simple issue of wrong connections and a straight forward fix. Really looking forward to any help and advice available!

Many Thanks in Advance!!

I suspect you need a SENT model JB4 and have an analog model JB4.... Email us and we can swap it for you.
