Fan, code 2EFE. Suspect fan is goosed

[ph001]

This should never have been difficult to diagnose. Check electrical continuity of green wire with needle test probes. Check 12V present on power connectors. Test fan with INPA.

I'm never convinced with diagnostics at garages.
There is 12v present (even on the fan when unplugged, so must be a capacitor there).

From experience here, the fault is more than likely with the wire. I shall try and do an end to end continuity check.
Does it plug into the DME? Whereabouts is that?

Also, what coolant sensor do I disconnect to force the fan on?

You need INPA, I'm with ph001, everything else is half hearted if you cannot fire the signal to test it and diag from there ....

Update.
I got another contact pin from BMW (part number 12 52 1 427 612 - about 70p), spent a hot afternoon digging the old pin out and crimping a new length of wire, and hey presto, fan works.

Before you all say "we told you so", I've had two renowned BMW independent garages fail to sort this, at my expense. I'm going to go back to Walkers and argue their incorrect diagnosis and see what they say.

Fixing this was one challenge, getting anything out of a garage will be another.

I now have a spare fan (along with radiator and condenser) if anyone is interested. Oh, that fan definitely works too!

Glad you got it sorted, not the weather to sit in jams not knowing if the fan works

The knowledge base on this forum trumps any garage trying to make a buck. Although a independent should know better ...

Nice one, glad you got it sorted in the end.
