Project goal: Drive to the beach without touching the gas or the brake.

Thanks to everyone who voted on my summer project thread. I was going to do the soft close door retrofit but the deal I had lined up for the parts fell through and I found another deal on the parts for this retrofit. It is such a tragedy that my current ACC retrofit only goes down to 20 miles an hour and I have to use actual force to press the brake pedal down. Then, when I am on the motorway even on the shortest following distance setting does not tailgate the person in front of me like a true BMW driver. Hopefully this new system will tailgate like a proper BMW driver.

Current unknowns:

Will E70 ACC parts play nice with the E90?
Where will I mount the new sensor?
Will the sensor like being center mounted instead off to the side like on the E70?

Parts List:

E70 ACC S+G sensor
E70 ACC S+G distance module
E90 ACC stalk
E70 ACC trim
F30 ACC bracket
VW Passat ACC harness
Bolts and screws

Functional Description

Wiring Diagram

Sensor dimensions: 12x8.5x4 CM

Instead of the ACC sensor getting PT can like the E90 ACC the S+G sensor gets special S can from the new LDM. My current plan is to plastic weld the E70 ACC trim to my pre lci E90 lower front grill. I believe the sensor needs a nice thin plastic trim over the sensor to protect it from road damage. For the actual mounting bracket I want to use a F30 ACC bracket and center mount it in between the crash bar and a lower plastic bracket.

I have no idea if this will work but it is worth the try.
