Suspension Control Unit (EHC) is bad

[gelafont]

The dealer concluded, all the suspension system and components check okay, but the control module (EHC) is unresponsive and therefore needs to be replaced. Could this module is so sensitive to just go bad because it was driven on lift and spit out Inactive Suspension error? All this happened after a fully functional Active Suspension (with no prior suspension error) was brought to a local friend shop for front brake replacement, while on the lift, test drove the car to replicate a weird sound coming from rear tire. Upon putting back the X5 on the ground, it did not go back to its normal height. I tried resetting it by unpluggling the battery and leave it over 15+mins and drove it for a while. it was all to no help. I ended up taking it to the dealer. And now the dealer wants to charge me $1400 to change the suspension control module. if this is really the case--the EHC is no good, is there any where i can find that module cheaper, even a used one. Any suggestions would be greatly appreciated

2-axle EHC or EHC-II is not cheap and can only be purchased through BMW.

My warranty replaced mine since it was throwing errors when it shouldn't have.

1-axle EHC or EHC-I is much cheaper, at around $150-$200, I believe.

thanks for the replied!
I guess mine is the EHC-II since it's an all 4 wheels Active Suspension. What I'd like to know, can this module really go bad because I had it on a lift and drove it. I feel the dealer is trying to rip me off by not wanting to reset and reprogrammed the module. I already told them i'm not fixing it. Is there any test, or anything else i can do verify if infact module is bad....

Only the dealer, for what I've seen so far, can test the module and the other components around it (pressure accumulator tank, compressor, valve block, sensors)

I was told there's some place in CA that repair them. does anyone know of this place or else where i can get the EHC module repaired or bought use or refurbished?
