It's been a while since I checked in. I wish I had earlier, since someone mentioned seeking an 06 M45 sensor.
You guys have made quite a lot of progress deciphering the ins and outs of the system. Congrats.
Brickbox, if I understand your situation, you now have a working sensor, it just seems to acknowledge taller profiles on the right lane, correct?
I can't clarify this, but if you felt froggy enough to take this leap, maybe a disassembly to investigate the internals would help? Approximately how high off the ground are the sensors in the SUVs compared to the sedans? How much plastic overhang is there to be cleared?
I ask this after skimming over the
technical bulletin (thanks for the link btw)
I believe that the sensors are at different heights on the vehicles, and according to the bulletin are aligned to different offsets from center (Q45 rightfully so seems to take the centerline point of reference) and also reference to the adjustment tool at different depths (more of a modern/ older model issue it seems)
Is it possible that your sensor & bracket combo is
aiming the beam (whether physically or digitally by default)
way to the right as someone alluded to,
as well as a little too high since the sedans are mounted a little lower and have to beam right+up to see others?
Pardon me if I get the positions wrong, I know I have seen an R50 with the ICC but I am having trouble locating a picture at this moment.
Maybe a frontal picture of your car would help.
I had an issue with the sensor of a newer sedan not picking up non-semis and randomly picking up cracks in the road. It's like it was aimed too high and too low at the same time. I suppose this was after an accident that somehow "scattered its brain".
I also assume most parted out sensors you would buy online would be from cars in some sort of accident - either impact or god forbid, water damage - either way, not ideal for electronics from what I know.
I had a dealer
realign my original sensor and all seemed to work well.
this is the link in which I shared my experience
Also remember that to sense vehicles, the other vehicle has to be in some relative motion as well. A stationary vehicle is unlikely to be acknowledged, if your speed will still allow you to even engage cruise.
On the housekeeping stuff:
1. Would you still like me to label the thread as
SOLVED? Either way, I am considering making it a sticky for the sheer amount of info that people like you and I (who like every feature working in our autos no matter the age) would find invaluable.
2. When posting pictures from IMGUR, to make them display here, I use the BBCode from the list of options. That is the forum-friendly one.
