Hi guys,

I have my N52 F10 stalled on highway and cannot start again few days ago.
No error messages dispalyed on iDrive.
The car cranks but it just wont start.

Checked with ISTA+ and the only fault code found is 1B5102 Terminal 15N_3: line from CAS, electric: short circuit to earth.

Does anyone have any idea?

I have tried to replace these items but no luck. Same code is still existed.
- new starter
- new fuel pump
- new integrated supply module

Cheers
