Hi all.
Have this code which is doing my head in.
Car is 2006 E90 320i
No IBS installed on this car so no battery coding required so I'm informed.
No other faults present.
I can read the code on INPA but it won't clear. It just comes straight back.
Have tried 2.2k resistor bypass and still failed.
Have accessed ignition circuits on INPA but only see circuits 1-7.
Can this fault be stored in the MRS ?
Can I probe the BST wires to check the MRS module for continuity.

First, I want you to know that I don't know the fix to your problem.
However, If you have checked the connections to the postiive terminal of the battery. I would check the negative terminal connections and the ground connection from the battery. Connections tend to corrode as a car ages.

Anyone!

Have swapped MRS module - no change
Continuity check = good
Measured resistance = 2.180 ohms
Swapped seats = no change
Checked earths
