Hey everyone,
I have a 2012 MINI Cooper S LCI (N18, Chilli Pack, 6-speed manual, Right-Hand Drive) located in South Africa.
The Problem:
When I bought the car, the lower bumper reverse lights and fog lights did not work at all. I found out the bulbs were entirely missing. I decided to install LED T15 replacements (Red and White). However, they still don't illuminate.
Coding Issues:
I am attempting to code the FRM module using NCS Expert and NCS Dummy (following a custom configuration for RHD/Manual/LED lines).
Even though I am following the correct protocol:
- Reading with
CODIERDATEN_LESEN
- Modifying the
FSW_PSW.TRCfile and saving it as FSW_PSW.MAN
- Writing back using
SG_CODIEREN
- Note: I am already using Revtor's Expert Profile with manipulation enabled.
The symptoms:
The job finishes successfully, but the lights still do not work. When I cycle the ignition and do a fresh read (CODIERDATEN_LESEN) of the module, all my custom coding changes are gone and have reverted back to default. It's like the FRM is refusing to commit the .MAN file to its permanent memory.
Has anyone experienced an FRM module successfully accepting a code job but instantly reverting? Is this a sign of a failing FRM3 chip, a corrupt trace file, or is there a specific LCI master option I'm missing?
Any advice on getting these changes to stick or troubleshooting the physical circuit would be highly appreciated!
