Technical Ducato 3.0 2008 fog light relay

[dom1961]

Hi all
I have failed mot ducato 3.0 2008 Motorhome, front fog light's. Could anyone tell me we're the relays are for fog lights and do you think it would be easiest to run new power from bottom of said relay to get them to fire up. The switch on the dashboard light's up but I don't have any front fog lights fitted. Or alternatively should there be a block to connect to near the headlights.
TIA

I, and others on this forum appreciate feedback rather than "TIA", which suggests no intention to report on the usefulness of advice given. My first reaction was just to ignore the OP's request, but it seems that I am not that mean.
The described situation is ananomly, as foglights were probably an option, and if not fitted there should be a blank cap on the switch.
On my 2006 x244 the foglights were not fitted on manufacture, and the connectors were parked on dummy plugs adjacent to the foglight positions.
The foglight relay and fuse are located in the engine bay fusebox. See attached pdf file.

Hi.
Thank you for the quick response and information. Sorry for the TIA I always respond to people. I have my fingers crossed it has the connection near the position. Can I presume that the relay is being energised because the dash switch lights up. Thank you again.

Is it based on a Ducato X250 as 2008? If it is the fog lights are switched by the Body Control Module BCM. Can you post a photo of the dash with the fog light illuminator showing?
Are front fog lights mandatory? Mine are a factory fitted option so I guess not? If they are not fitted and not mandatory why not just disable the switch if this is causing the tester to fail them?

I think that it could just be an indication that the switch has been pressed. If wishing to confirm relay operation, you could either locate a foglight lead and check for 12V when the button is pressed with ignition on, or remove fusebox cover and hold a finger on the relay while an assistant presses the switch with ignition on.

I'm pretty sure that my 2015 A Class Hymer has the switch, which illuminates the dash light, but doesn't have front fogs or the holes for them. Never failed the MOT.

The UK MOT does not require front fog lights for vehicles registered before 2018. Even if fitted they should not be tested.

The only information I have on the Spanish equivalent, the ITV test, is that position, road and fog lights must work correctly. If your vehicle is not and never has been fitted with front fog lights and its registration age does not demand them in Spain, it is quite unreasonable to fail it because there is a redundant switch. I appreciate that "reasonable" and "official test" don't always go hand-in hand !

If it were me I would remove/blank off the switch and its lamp.

Rear fog lights are a different matter.

In Poland (and perhaps other EU countries, too), the law requires any installed lighting to be operationnal.

If this lighting is not mandatory, it can then be removed. But if it is installed, it has to work.

On the 2011 x250 the relay is a small one, looks like that:

And is located in the fuse / relay box under the bonnet. Position T14. The fuse is F30.

The fog light will work only with the side lights on. But the dash light should not illuminate if the side lights are not switched on. Both D050A / D050B and F015 / F016 connectors are hermetic, so there should be no rust inside. Unless someone messed with it. The last piece of the loom (between the mentionned connectors) is quite exposed to mechanical damage unless your van is equipped with the side undertray covers.

Here's the description taken from the eLearn module (an extract, more or less what @Communicator posted above)

The (negative) analogue signal for activating the fog lights reaches pin 35 of connector B of the Body Computer M001 from the control button located in the centre switch panel H090 (pin 9).

The activation signal for the side lights reaches pin 2 of connector B of the Body Computer M001 from the steering column switch unit H005 (pin 7 of connector A).

See E2010 SIDE LIGHTS / NO. PLATE LIGHTS

The Body Computer M001 (pin 11 of connector A) controls the power supply for the fog lights sending an earth signal to the engine compartment junction unit B001 (pin 23 of connector A) which energizes the coil for relay T14 closing the contact and providing a power supply from pins 4 and 5 of the connector B for B001 for the left F015 and right F016 fog lights.

The circuit is protected by fuse F30 of the engine compartment junction unit B001.

Both fog lights are connected, via respective pins 2, to the left front earth C010.

The Body Computer M001 is connected, via the CAN line (pins 5 and 6 of connector B) to the instrument panel E050 (PINS 5 AND 6) to manage the "fog lights on" warning light.

A few more things:

if the fog lights have not been fitted (as in my van), there should be no T14 relay in the fusebox. Can't remember for the fuse, I think it was present.

The last part of the loom I've mentionned earlier was also absent, the factory loom ended with the D050 connectors, attached somewhere to the body.

I had no switch on the dash (there are two possible locations for it: the central panel with the warning lights switch or the driver's outside knee panel with the dashboard menu buttons). Both panels exists like in thousands of versions depending on the equipment installed. The list is too long to even try to list it

So I had no possibility to light up the dashboard light otherwise than from MultiEcuScan.

The question is: were the foglights installed beforehand and taken off the van? For how long have you got it? Perhaps the installation was modified for any extra lighting to be switched on with the fog lights button? Like a lightbar?

There are no plastic covers for the x250 front bumper fog lights. It is basically the same bumper no matter if the van is equipped with fog lights or not, simply some additionnal holes need to be cut when you retrofit the fog lights. Then a mounting bracket is required, which is installed on the back of the bumper.

If you don't own the van from new I suppose that the fog lights (or any other external lights) have been removed. Or the van had an accident and the bumper was replaced, but no one cared about the fog lights.

Can you post a photo of the front of the van, showing also the bottom of the bumper, please?

Hi,

Thank you all for your help, all sorted relay 14 was clicking when switch was pressed and I used it to switch lamps. Perfect solution I just wasn't looking forward to getting a wire through the bulkhead.

Thanks again.
