Actually I am looking into the retrofit. I have already chased down two versions of the ABS control module that are NOT natural upgrades but different parts altogether, based on 2 separate VIN numbers. They are actually priced $110 apart, with the newer more expensive unit for the later models that have the ACC W/ STOP capability. There's also a 100 dollar price difference between the Adv. Tech Group packages for these 2 VINs. I also contacted Bosch Germany and I established that the LRR3 unit must be the same (the radar eye at the front) because the LRR4 has not made it into production yet. I was then referred to Bosch USA and now I am working that angle.
I believe retrofit is possible, but at what price and how involved. ABS control unit? Not so much. Additional sensors...well that gets complicated.
I could use some help. Who's interested?
My Jeep, built in April, has this ABS Module:
68199249AC, currently replaced by 68199249AH
And then there is the ABS Control Unit, on the newer Jeep
This is the sensor
Distance 0.5…250 m
Accuracy ±0.1 m
Relative speed -75 …+60 m/s
Accuracy ±0.12 m/s
Which is the same between both cars.
Still working on it. I would love it it it boiled down to a few hundred dollars and one - two modules. I don't know yet.
