Hi,

I have just finished installing my JB4 on 2014 320i and got this message on the JB4 mobile APP.

Anybody knows what is this related to ?

Should I be concerned?

error code: 1D2404 Map thermostat, line disconnected

Thanks.

Faulty thermostat, it's a know issue. They replace mine under warranty. If your in Sport+ and temps are not below 210 then it's not responding to the map change/going into efficiency mode of heating to 240 for fuel economy. From my understanding and what happened anyways. Car runs so much cooler after the new ones in.

Google the TSB (technical service bulletin) applicable to your production date and give it to your SA, unless ur SA is cool enough you can show him the code from the jb4
