I can't see that it is anything else.

Ok, thanks I will call them again and see what happens this time.
I really can't understand why it is such a big deal, they must have had to enable tow electrics before.
Thanks for your help.

Can you not try some one local with an iid tool to see what is configured for you. they wouldn't be able to set it for you unless it was the iid pro.L633 Defender

Is this something as simple as 13 pin electrics enabled when you clearly have 7 pin?

Don't think so.

Thanks for all your replies
I will call the garage in the morning to try again, but I hold little faith as they already had the car for a day and apparently checked all the settings. The trip mileage and clock had been reset when I collected the car from them, so I assume they did some kind of testing or fiddling around.
I don't know anyone locally in North London with a iid tool but I have been to another garage who I like called Brownchurch, so will go to them if North One still can't find the fault.

Hello All
So I have just received this back from the garage:
"We’ve been through the main vehicle loom wiring diagrams confirming that while the bulk of the wiring In question runs through connector blocks etc. that usually could be considered a potential cause, the yellow and green indicator wires run directly from the CJB (central junction box) meaning there is either damage to the CJB-rear connector wiring that we would be able to overlay, or an internal failure of the CJB itself. Again unfortunately, programming/regional settings etc. are confirmed not to be the cause of the issue."
I am not sure what my next course of action should be. Really I would like to have the tow electrics working correctly, but with my experience so far, I assume that the overlaying cables will not work and the garage will end up suggesting a new CJB, then when that doesn't work there will be another hugely expensive item I need.
Do any of you have an idea of what I should do, are there more tests I could carry out myself?
Thanks for your help.

I guess there is a vague possibility it could be the CJB.
It would be very expensive to replace the CJB and for it to not fix it.
I think I would buy an IID for £425 (still cheaper than a CJB replacement!) and does loads of amazing things and check the settings yourself. These hold there value, so you could sell it on here if you wish.
or find someone local to you and pay them £65 for a licencee for your car
Nothing more you can do.
Well, apart from, turn the ignition on, then connect up a 21W bulb to ONE indicator. Then press the brake and see if it lights.
But its just playing really.
If it didn't light on brakes then it points more to a programming issue.
If it lights, no further forward

It is surprising what can be done with an unlicensed Iid tool, it is possible one would read the ccf but not change it.It can when others can't,
It will when others won't,
It goes where others don't.

I did wonder.
I suspect lots of different settings may need to be tried ?
Battery charger needs connecting while this is done.

Any unusual faults with brake lights or indicators and I think brake light bulbs and switch start with the cheapest option is my moto, not the most expensive CJB as LR do It can when others can't,
It will when others won't,
It goes where others don't.

Thanks for your replies.

The way I carried out the tests on the wiring was by using a 21w bulb with the ground on the chassis. I then placed the positive in to each of the terminal outputs, so I have already tried one bulb on one indicator output. The indicator is fine, but when the brake is pressed the indicator output is live regardless of the the indicator being on or off.

When you mention brake light bulbs and switch, do you have any recommendations of what I should look for?
I don't think I will buy an IID myself but if I can't get any further then I will go to someone who has one.
I am still sure it is a programming issue and I pushed the dealer on this but they are adamant that all that has been checked so it is another fault. I also asked why the reversing sensors and ride height operate while the tow board is connected, but apparently this is a mystery as well.
I just can't see why they would have the car three times, read my instructions and not ensure the programming is correct.
Any other thoughts or checks I can do would be good. but failing that I will go to another garage with an IID tool.
Thanks
