2012 335xi coupe catless DP and JB4

PghBMW · 02-14-2018, 12:31 PM

Just wanted to survey the group. The CPO warranty on my 335 expires here soon and I wanted to make some changes to the DP and possibly add a JB4 unit to the car.

The main question I wanted to ask, has anyone had any issues with the electrical components to their car after wiring in the JB4 unit to the OEM fuse box?

You should have no issues wiring the JB4. It doesn't wire into the fuse box at all. Plugs into the sensors and the CAN wires, and into the main fuse in the ECU box.the wire is just pushed into the fuse so it doesn't alter its function, etc..

Have never seen anyone with an issue.

As Mike said, you will have no issues as it does not wire to the fuse box.
Good luck and let us know how you like it
