Ride Height Sensor

Post by TrackRat »

I posted the pin out on the FB post, but here is the actual diagram from the book. Looks like only pins 1,4, and 5 are used. Leads on 1 and 5 with the wiper arm on 4. Not sure the values.

Future reference, you can get all the wiring diagrams for BMW's here:

My god. I think I just died and went to motorsports heaven. If that's accurate we have a very compelling suspension datalogging solution.

Any idea on the connector?

Not sure on the connector. Not sure where to get that one.

Just verified a 0.1 to 4.9v voltage swing across 90 degrees of travel, using the diagram above. Looks like we have suspension travel sensor! :D

What was the resistance values and what did you use for the pull down?

No resistance needed. Ignore what's in the ECU box; that's just for your reference. The device produces a variable voltage output.

Whoa nice find! These could be useful for a lot more than suspension travel too!

They're amazing! Our new intern will be installing 4 of them on a race car and documenting the installation. Actually kind of jealous, they're that cool! :)

We're spinning up possbily using these sensors on a sponsored nascar vehicle. Anyone know the connector for this sensor?

Never mind; this looks like the connector housing:

Update. The connector does not come pins and wires. To complete the installation you would need individual wire pigtails.

61130005199 for white wire
61130006665 for red with stripe

I imagine there may be other wire color combinations available.

Evidently you will need 3 wires for GND, 5v and signal.

Hey

Is there an update how good and reliable it works?

While we didn't followup, these type of sensors typically work very well. It is the best, if not cheapest, option for determining ride height.
