Hi everyone. I'm a newb. I bought this 2003 LX470 earlier this year. The AHC system indicator sometimes shows middle and high, but the car never moves up or down and drives great. The person I bought it from sold it for his older dad. He didn't know much. I assume the Bilstein setup replaces the AHC, though the equipment is still there and I don't see any cut lines etc. Can someone tell me what they notice from the pictures? Thanks for any help
