Rear Wheel Carrier and Parking Sensors

Thanks for all those who have offered insight on this. I intend to take it back to supplier when I am in Perth next in December, and he says their R&D is working on the problem, but nil success so far.
Seems part of problem might be that I had a full carrier fitted rather than a bolt through. Sellers thought the problem sending off the sensors was the "latches" for the wheel carriers and reckon they have since modified them, but sensors still go off. Latches do protrude a bit when closed.
Sensors in my carrier are not flush (as in origional bumper), but slightly recessed. Sensors in "Bolt through" carrier have not been moved/reset.
Since some mention a change of tyre tread, problem may be related to how much overhang of wheel from back of vehicle.
Top inside of frame is 145mm from tailgate, top inside of tyre is 200mm from tailgate at closest.
Are the distances on the "bolt through" carriers any closer to the tailgate?
Still peeved that no mention made of this issue when sold item, but was told it was a new model.....so buyer beware I suppose.
Aplogies if pics too small, I reduced them and upload seems to have shrunk them more.

vrab - I just ducked outside and measured mine. Very close to the same measurements that you have shown in your photo.

Tyre to glass at closest point is 210mm, frame to body at top of post is 145mm.

Latch on mine looks very similar to yours, but I have just noticed that they have removed one of the reversing sensors (never noticed that before - system still works exactly the same with only three sensors).

Hard to tell from the photos, and also because we have different bumpers - but it looks to me like the tyre on mine may sit slightly higher than yours do, which would put it slightly further away from the right side sensor.

If you open your latches and swing your tyres out, and then select reverse - does the beeper still go off ?

Looking at the photo of yours, I'd strongly suspect that it is the two latches being in close proximity to the two centre sensors that might be causing the problem, rather than the wheels / tyres. Add to this the fact that mine has the sensor removed where the latch is located and it adds to the suspicion - just a thought.

Hope this helps .......................... BM

Thanks for checking measurements, doesn't seem to be much difference between the set ups from body.
I get the noise for about 5 seconds every time I put the key in, regardless of whether spares open or "closed".
I attach pics of how far recesssed the sensors are, they may be picking up the bumperas they appear to be set back inside it.

@ discojools.

Sorry that I have ben quite tardy in responding. This is a picture of my rear inner right sensor with a furniture protector applied. I know the car is dirty but if you ignore that you can see the shape of the rubber. The sensor still works as normal for the areas not shielded by the wheel on the carrier. The outer sensor covers the rest. This solution seems (to me at least) to be better than totally disabling the sensor.

Thanks Fred, I will try adjusting mine to match yours. At the moment mine is completely blanked.

This suggests a sensor wiring fault to me.

I am new to this forum and in the process of changing from a 200series to possibly a new D4. I plan on adding many accessories listed here and I would like to know if the reverse camera can still be used with a twin rear wheel carrier or does the wheels cover the camera?
Great site BTW

The camera is located in the upper tailgate in the number plate light/handle cluster.

As number plate light etc has to be relocated when fitting twin wheel carriers you would think that the camera could be relocated as well.
