After some reading on the forum I discovered a few members have installed E70 EHC modules and have them successfully working with auto height regulation like a factory EHC module. I got one off ebay part number 6778966 because it says e6x/e7x which made me assume this is the module others have installed. Unfortunately this module seems to read the ride height sensors on both sides of the car in reverse, meaning as the car raises the height values shown in INPA decreases instead of increasing. I was wondering if anyone could care to chime in on the part number they successfully used or what programming, if any, there is to correct this behavior.

 

You just installed it and expected it to work or did you program and calibrate it first?

 

I did do a calibration successfully but it doesn't matter because the EHC has the height sensors flipped so it either fully deflates the airbags because it wants to lower the car but thinks the car is increasing in ride height or it continously runs the compressor trying to raise the height but thinks the car is lowering instead.
