hello everyone,

So I have a bit of a challenge. My parents bought a f21 lci and it has a decent amount of options.

Lane departure warning, lane assist, 360 camera, active cruise control, NBT evo.
since it has the lane assist and departure warning i wanted to put a steerwheel heater button in it and code it.

unfortunatelly some options are retrofitted and I think this is where the problem comes from. 

I added option 248 to the FA and read ecu with esys and pushed "code" on the FEM, NBT and Kombi.

to my surprise the lane departure warning stopped working and the screen of the NBT went dark.

i had code B7F8E5 and fixed that with tool32 (TELNET_ZUGANG_AUS)

now the NBT is green in the module tree but still nothing on screen, audio works.

codes I have now are:

801A50: SINE: fault in speaker circuit detected
This is a faulty alarm speaker i guess.

CAAC0D: CAS/ FEM interface (ZV and lid status, 0x2FC: signal invalid

CB1612: message (radar sensor, rear-wheel drive, 260.1.4) missing

D90D19: assist system operating unit (BEFAS) (LIN): incorrect version installed

anyone got any idea what to do? i`m kinda stressing here..


Kind regards,
Stefan.
