E61 Air suspension / EHS Module / flood
 

Hey everyone,
Just wanted to tell small story and give heads up for those who seek solution on this topic.

I got the car with flooded trunk, EHC module were dead, if you're in the same situation, don't be too much upset.
According to realOEM my EHC module part number is 37146784314, which was impossible to find cheap.
BUT, you can get the 3714669834 and it will work.(I got the part for $240 from ebay in Europe) it's PnP (no coding needed)
Then you check your fuses (2 of them) and relay (the green one)
While you're waiting for the part you can pump airbags manually, you just need to remover plastic cover underneath the back of your car on the passenger side.
There will be a pump. You need to disconnect air supply hose and connect it to air compressor,
then you need to find plug with 2 blue wires and one red wire in the back of the air pump. Put 12V there to open the valve and pump it.
That's not really hard.

I hope it will help someone.
Cheers
