Yet another problem with my 318i.
The electric cooling fan system has an intermitent fault causing the fan not to cut-in when required. Diagnostic code from Autodiagnos scanner states "108 - Activation, electric fan short circuit to B- /electric fan malfunction
Any one know how to test the electric cooling fan? Fan has a permanent 12V supply and is controlled from ECU with variable pulse width signal via another electronic module attached to the fan mounting frame.
