I just picked up the OEM Mini 2nd Gen LED DRL that have the Halo light for DRLs. I finished installing them and I have a question I hope someone who has installed them could answer. Right now when I turn the car on they are the half crescent. When I put the parking lights on they are the Halo, and when the lights are on they are the half crescent. When I turn on the fog lights nothing happens. I'm thinking I somehow messed up on the installation of the wire tap at Pin 12 (gray wire) in the footwell module. Could anyone confirm that's what I would be seeing if I in fact messed up the wire tap?

Thanks!

 

A quick check would be to disconnect the wire at the footwell module. That effectively cancels out the halo ring DRL. With that wire disconnected, you should have zero illumination with the lights off, the upper half-halo with parking lights, and full center illumination with fog lights.

After that test, double check the connections at the fog lights. I am pretty sure the harness plugs will only connect one way, but it might be possible that you plugged the parking light socket into the fog on the DRL harness, and the fog socket into the parking on the DRL harness.

 

Thanks for the quick reply! I'll be pulling out the footwell module today to check my connection. I agree about the fog light connection...it's almost impossible to mess it up due to one set of pins being horizontal and the other vertical so I don't think that is an issue, but the car is still on jacks and half torn apart for a bunch of other work I did so I'm going to check.

 

So this is what I have so far:

When the Pin 12(Gray Cable) was disconnected I show the following indications:
-Lights On: Crescent
-Parking Lights: Crescent
-Off: Nothing
-Fogs: Crescent

When the Pin 12(Gray Cable) is connected I have the following indications:
-Lights On: Crescent
-Parking Lights: Crescent
-Off: Halo
-Fogs: Crescent

I have the DRLs turned off in the menu as the instructions indicate. What am I missing? I've enclosed a picture of one of the wire connections for the fogs.

 

Are you missing a ground wire somewhere?

Everything else sounds correct, except when the fogs are switched on...

 

The only ground wire I can think of is the one that is installed underneath the fuse/relay box and I checked that. I'll check it again. This is frustrating. Thanks!

 

Is the operation the same on both sides? All I can think is the fog circuit is grounding through the parking light, or something like that....

 

Yes, both sides are the same. I thought of that as well just not sure where the ground would be.

 

I just plugged in the old fog light on the driver side and when I turned the fog light switch on it came right on. The upper bulb isn’t coming on but that’s tied to the DRL in the menu correct?

 

You can't turn them fog lights on without turning on the running lights, correct? The OEM function with DRLs off should be all off with switches off, upper light with running lights, upper and fog light with fogs on. Is the function of the running lights correct on the OEM housing?

 

Also just undid the ground wire they have you do as part of the install to verify what I should get. New fog lights would do nothing at all and I even got a “fog lights not working light” so that proves the ground there is good.

 

Going to verify your last thread here in a second. Thanks for all your help!

 

Ok just reconnected ground and hooked the OEM back up. With the DRL on the upper bulb is on with it off it is off. With fogs on the whole housing is lit with DRLs on and only the fog is on with DRL off.

 

Yeah, I'm at a loss with what's going on with your car...

What is the operation with DRL off in the menu, and OEM fog housings installed?
-Off: ???
-Parking Lights: ???
-Fogs: ???
-Lights On: ???

 

DRL. Off on menu and original fogs installed

off-nothing
parking-nothing
headlights-nothing
fogs-fog bulb on upper bulb off

 

Does one fuse control the entire housing? Just thinking....

 

I know I'm talking to myself at this point hahaha, but I'm keeping notes here in case anyone else runs into a similar issue. I'm the third owner of this car and it is modified a bit. I have Carly to code the car so I'm now wondering how exactly the MINI LED DRLs work as in how the signal tells the fogs to come on. The reason I ask is maybe something was coded out that would make the old OEM fogs work fine but not the LEDS. Not sure if anyone know exactly how the control box sends its signals.

Also, because I've completely forgotten at this point, but the bulbs in the top of the OEM fogs housing....what is the proper term for those and under what cases do they come on(for troubleshooting purposes.)

 

The Mini OEM LED fog module gets the DRL signal from the connection inside at the FRM - the trigger wire you snake into the cabin for the installation. The module also gets the parking light trigger signal from the parking light socket, and the fog light trigger from the fog light socket, both of which are the connections made down at the housing.

The upper bulb in the OEM housing is the parking light. The parking light should be on whenever the light switch is turned on.

This is why I asked about the function when the OEM housings were installed. If something doesn't work right with the original housing configuration, trying to troubleshoot with the LED set-up will be more difficult.

I also have Carly, and I can't think of any coding configuration that would cause the fogs not to work correctly.

 

Thanks...going to triple check everything now

 

Ok, so the plot thickens. I checked the fog light wiring per the 'updated' wiring diagrams from the instructions and the left side (driver) looks correct. I then checked the right (passenger) side and this is what I found. The enclosed screenshot is from the updated wiring diagram:


We are looking at modules X769 (side marker-upper bulb connection) and X136 (fog light bulb connection). The color of the wires that are supposed to go to them are Yellow and Green respectively.


This is the yellow wire obviously. Notice how the pins are vertical

This is the green wire obviously. Notice how the pins are horizontal

This is unit X136 to the fog light bulb. Notice how the pin receiver is vertical

This is unit X769 to the side marker/upper bulb. Notice how the pin receiver is horizontal


So according to the "updated" wiring diagram I need to shove the round peg into the square hole and the square peg into the round hole? Any ideas?

 

The plot thickens more...

 

Might be a stupid question, but do you have that fog housing plugged in?

I said this before, might be worth the effort to go completely back to stock configuration and verify operation prior to going forward.

 

When you say the "stock housing plugged in" are you referring to at the bulb of at the other end of the cable? I would guess that would be in the footwell module? I have gone back to stock and everything worked then as I have described in the above posts.

What are your thoughts on the wiring diagram indicating that the cabling is backwards?

 

Yes, bulbs plugged into the factory harness, nothing plugged into the LED harness, as if the car were stock.

I'll be swapping my wheels over to snows either this afternoon or tomorrow. I'll try to get some pictures of my LED fog installation....

 

Thanks again for the help! I’m very interested to see what color wire goes to what in your install on the left side. I’ll probably do the stock hookup again later. I’m just having fun driving around after not being in the car for a couple months now. Haha
