Thread: Gen II Calibration

Ah, okay. I think I understand now. You can swap them over on the newer ones, it just won't do as much unless you've also changed your normal height as well.

The reason that the replacement pre-97 sensors have different part numbers is because LR no longer supplies the original pre-97 sensor, which is why originally the Part database had only one part (ANR2494) which has been superseded with the two separate part numbers.

They instead supply the newer style sensor, which can go on either side, however as it mounts slightly differently it comes with an extra mounting bracket to fit the newer style sensor which is handed (the bracket, I mean).

On the newer post-97 sensor, I was wrong; it is not handed. However, swapping side to side on the newer sensor will not help as it does with the old sensor as there are two sets of arms inside the sensor which run on opposite side of tracks in the same offset (see photograph to see what I mean). Hence, the wearing is in the same spots when you twist it around.

On the older pre-97 sensors, they have two separate tracks, with two arms that are positioned on the same side. Hence, when you swap it over you turn the arms to a fresh side of the track.

See these photographs to see what I mean:
This is the pre-97 sensor:


This is the post-97 sensor:


This is the bracket that comes with the replacement for the pre-97 sensor (this is right hand side, the LHS one is slightly different - there are also matching shields):


I spent way too much time on that haha...

EDIT: Here's the kit, by the way:

I can confirm that swapping the later sensors side to side seems to have no affect.

If you're feeling adventurous, you could try cutting it open and gently cleaning the track. I wouldn't hold much hope though.

You *may* be able to slightly bend the wiper arms over half a millimetre or so to a better part of the track but there really is almost no room to do that on the newer sensors.

Sadly, I'd say it's new sensor time if you're sure it's a sensor fault.
