On older BMW models car speed was determined based on exactly rear right wheel speed sensor.

As I know it was based on rear left sensor not right.

As you said water on the front passenger floor. You should check the BDC pin/contact for corrosion.
Corrosion = High resistance, shorted and intermittent faults.

New bdc installed there and coded. Beside this there was not any corrosion.

Lets talk about active errors.

48239c and d01b2a
Why it writes eps torque sensor index faulty when sensor warks, eps makes adaptation, it sees angles?
And what does it mean second error- signal invalid, tramsmotter eps.

Why we see these?

Definitely some modules are wet or wires are wet. Need to determine which modules can cause these errors.

I removed carpet from car. I have access to all connectors. Do not think that modules are wet. Contacs are cleaned but same errors there..

I replaced horns and now horn works but every other errors are left.

Noone knows ?

Update
Found water in only tailgate control module connectors. I replaced module and cleaned wires. I think it could mess up something but replacing it did not help my errors at all.

Rse, icm, bdc all were clean and no water in them or connectors.


I think now I have ethernet connection because added error: ethernet connection from head unit to RSE high. Existent no.

And also during test plan of eps errors, it mentions ethernet connrction too.

P.s.
Checked eps wires, abs wires, rse wires, all good.

All errors are solved buy updating software in trunk module. Strange but worked.
