BMW E53 (X5) 2003 Battery Safety Terminal bypass

**pepi** · 29th April, 2015, 05:31 PM

I am trying to bypass resistance of BTS on E53 without success with resistance 2.2 ohm .
There is still error
MRS : Battery ,positive terminal isolation 1
Does any of you did it and what resistace value did you use for it .
Thanks in advance.

2.2 ohms ressitance

Cool read in a dirty magazine something daft like a 2 amp glass fuse is perfect

I already try with 2.2 ohm it didnt worked , I will try tomorrow with 3.3 ohm or even with 2A glass fuse.

Not worked again

Try 1 ohm..you know, if u have a good scanner you can just read the value the car is detecting. if 1 ohm dont work then use 2.2 and cut the freaking plug right off..and if that don't work then light car on fire and push it off a bridge..problem solve!

Tomorrow I will get same E53 and measure exact value .

I usually use 2.7 ohm and it always works. However the fault that you pick up sounds like what i had with an old bmw.
It kept giving me the same fault as you getting no matter what i did. I even tried to trace the wires up to module's plug and tried to put resistor there.
It did not work either. So i believe with a slight chance there might be something wrong with the module itself. Maybe that fault is recorded on it somehow.

Use 2.2 but cut the wires.
