Your 'Fella' knows little about such things - an exerpt:

Exterior lights and exterior light functions are controlled by the Light Module in the dashboard. Some of the exterior light functions include:
• Exterior bulb monitoring
• Bi-Xenon headlight operation

In addition, the LM keeps a redundant copy of vehicle data. This includes make and model of the vehicle plus current odometer and maintenance / service information. The same data is stored in the instrument cluster.

The headlight switch is located on the dashboard. Trim pieces are made of hard plastic. Plastic clips or metal screws may be used to hold them in place. To avoid marring the trim, work with a plastic prying tool or wrap a screwdriver tip with masking tape before prying out trim panels, switches or electrical accessories.

The headlight switch is located on the right side of the steering wheel. An indicator of a problem with the headlight switch would be non-functioning headlights with an illuminated instrument panel. You may also have a chime warning sound. The sound is similar to when you leave your headlights on when exiting the vehicle. The headlight switch is replaced as one unit. Once replaced, the switch requires programming using a scan tool.

If your headlights do not work but the warning chime is not on, you may have a faulty Light Module (LM). Use this article to see how to replace and test the input power and ground as well as outputs to the headlights.

When replacing your LM, a used replacement is not an option. In the past, we use to be able to grab a LM from a donor vehicle with a matching part number. That however is no longer the case. Late model BMW's and the early Range Rovers utilise an anti-theft system preventing swapping from vehicle to vehicle. This is due to the VIN being programmed in the LM. At the minimum, if you buy a unit, you will have to code, and program the LM. This has to be done using an advanced scan tool, such as an Autologic.

As we said before, as long as you are happy your fault is 'fixed' than happy days, but you can't hide from the fact the LCM stores vehicle specific information.

@Saint.V8 Any idea how having false data would fare, should there be an accident and for some reason it emerges? I know it's not your field but no harm in asking

The lack of vehicle information in the LCM will be of little interest to insurers UNLESS the accident *may* involve lack of lighting, incorrect lighting or similar, which is when they will look into the vehicle lighting system and deduce that the LCM is not 'correct' for the car and as such could use that to refuse any claim or the third party insurer to put the blame onto the vehicle with the 'incorrect' LCM - who's to say the vehicle exterior lighting was working correctly, they could argue that it wasn't the right one for the vehicle and as such some of the exterior lighting was not working correctly to warn others of the hazard or driver intention.

If the replacement LCM had a higher mileage stored, they could also use this higher mileage as a basis for correct market value calculations when deciding on payout.....who is to say the BCU and the Instrument Pack are showing an 'incorrect' lower mileage and the vehicle is indeed higher mileage as per the LCM - they could use that as a loophole too.

But that is purely speculation......but if the accident were to do with a situation involving lighting, be it lack of signalling at a junction, or lack of tail lights, brakes lights etc...they *may* just use the fact the LCM is 'incorrect' for the vehicle as a get out clause.

Remember, regardless of if it has an MOT (which checks the function of the lights) and it passed the tests, that just means that the lights worked on the day of the test and would have no bearing on a claim that would be subsequent to that MOT test, they would still be checking that the lighting system of the car was correct at the time of the accident, not at the time of the MOT!

You are right SV8, but words fail me.
