MOT failure: broken self adjusters but NO Xenons

[MissMoppet]

Just had an MOT failure due to a broken self adjusting arm or bracket BUT I have swapped the Xenons from this 04 motor to my "new" 02 Tourer. Am I right in thinking that these self adjusters are ONLY needed or fitted to cars with Xenons?

You must have left the sensor and arm in place, and the tester having seen it, would have failed it, if it wasn't there how would the tester have known from the information the system has?

If no xenon light you need an internal level switch on the lsm

Hi Dave.
So D3ave lincs, is correctly stated you need an LSM which matches the now non xenons on the 04 for it to pass, you could get another one, or use the one off the 02 to get it passed, then reinstate back to your 02 after.

You only need the front if i am right in my thinking no T4 involved, i could be wrong.

Unplug the ribbon and swap the fronts over.

Which type is in the 02.

Do not swap complete LSM as the mileage is stored in there for the IPK and you will have issues like err displayed on trip mileage

Hi Dave.
Just the fronts then correct

All these are/were virginised by (MB) way back

Thanks Steve for your photos, they're very helpful. When I retrofitted some front fog lights to a car, swapping the front of the LSM over (as shown in the photos) is exactly what I did. No T4 involved and is working perfectly. I assume the same would apply in this situation too.

Sorry Dave, this thread has got a bit confusing. Here's what I think you need to do.

Confirm what type of light switches each car has. If the 04 car has no level switch (thumb wheel), you'll need to swap the LSM fronts over. If both cars have a level switch (thumb wheel), that's fine, no work required there.

Remove the self-levelling sensors and brackets from the 04 car.

Don't worry about retrofitting the self-levelling sensors and brackets to the 02 car, it isn't an MoT requirement for them to be fitted, it's only requirement that they work IF they are fitted.

The MoT manual says that if a self-levelling system is fitted, it must work. However, your situation is a little unusual as, if I've understood it correctly, the 04 car has halogen headlights retrofitted but the self levelling equipment still attached. If you remove the self levelling stuff completely, I think you should get a pass.

Have you switched the light switches over? I might be wrong (someone please correct me if I am) but I believe the Xenon light switch module doesn't have the little wheel to adjust the beam height, whereas the Halogen version does.

You can't simply swap the modules over however as they're coded to the car. I think you have to separate the face plate and switches from the rest of the module, which is connected with a ribbon cable and some clips, and swap just that piece over. This might not be necessary, especially if the 04 car is already fitted with a light switch module that has the beam height adjustment wheel.

Yes the 02 Tourer has the thumb wheel - that now has the Xenons - but the 04 that has the non-working self levellers now has the transferred Halogens, so this gizmo is pointless and useless.

Does the 04 car also have an internal level switch (thumb wheel)? To Dave Lincs' point, the 04 car will need that thumb wheel now that it has halogens fitted.
