Hi guys I have a F20 pre LCI 116D, I have recently face lifted the rear end. I've visited an "BMW specialist auto electrician" Which has over charged me and not completed the job. All the lights are working apart from the left indicator. He say's it is to do with the module maybe having a fault. I think he just wants more work though as he quoted 90£ at the start and jumped up to 150 after having to add a couple of wires, wouldn't be so cheesed off if the job was completed and he didn't scratch my front bumper. He didn't mention anything of it but once I took it out saw it and was screwing... Any help would be appreciated. I was hoping it would be a simple job of tapping into the indicator in the front and running the wire through the car as I have to finish his job??

Why not set that side indication on and follow the wiring back and see where it's not working - or rather find out where it IS working then head to the indicator direction, see where you lose the signal, simple multimeter or one of those light up continuity testers may give results, realoem.com and your VIN might give an idea of location of things and how it's put together.
"BMW specialist auto electrician" - wouldn't allow him to make toast :)
Not THAT special then...
Old days before cars got so clever you'd probably get away with running from front to rear, but yours might notice that the front indicator was suddenly drawing double and complain, any other circuit you could probably add a relay except that wouldn't work on an indicator circuit.
If it IS a faulty module, see if you can track one down from a breakers, but you need more information, and the specialist you've had doesn't seem to know zip.

As thanatoid says, I can't imagine that the LKM would be amused at having two indicators run off the front - it would presumably play merry hell with the continuity test and throw a bulb out warning. Or just fall over and stop playing (as seen when trying to put over powered angel eye bulbs in)!

Thanks for the advice guys, so I’ve ended up getting a new moduel, good news the indicator is working again on both sides, but since changing the moduel the fog light triggers the reverse lights and the reverse gear triggers the fog lights, I plugged in the old module to check it wasn’t like that before and it wasn’t, the fog light worked normally and the reverse did too super weird, think it’s just a case of swapping the wires over??

also In the new module, the LED lights are on as DLR’s which I actually prefer and with the old module they would only come on with all the lights 🤷‍♂️

andd the new module doesn’t have PDC which I hope is just a case of having it coded in, I don’t really want to go back to that same “bmw specialist” but feel now he’s done the wiring it’s the only option?

The new module has to be coded anyways so it works correctly on your vehicle.

And on the old module that short circuit block for indicator could have been coded out too with for example Tool32.

Damn, do you think it’s just a case of having the module coded correctly to switch the fog and reverse lights over then?

I do have a coder local I could use but not sure if it’ll be a big job or quite straightforward, I don’t have much experience myself
