man, I guess the 04 4.8is had a lot of air ride issues. Not uncommon as that was the first year for the new suspension on the 4.8is. Seems like this is normal for all BMWs in the first year or two of production. Everything seems to get sorted out by the 3rd or 4th year.

Good luck with your repairs. The air ride can be very expensive to fix once it goes haywire. I was lucky most of my issues were replaced before I took ownership but when I viewed the service history, it could have been a nightmare to pay out of pocket.

Just a few months ago I replaced the front drivers strut and that ran about $750 (parts discount from friend at the dealer). Thankfully that is just a plug and play fix. The module will take time to code as others have pointed out.

:confused::confused::confused::confused:

here you go . this should help .
buy the service manual from Bentley Publishers Home *-* Bentley Publishers - Repair Manuals and Automotive Books and save yourself a lot of hassle . :wow: EDIT - move on a few posts to find the EHC2 module for cars with front and rear air . it`s behind the glove box , photos in post 32 .:thumbup: OK I just added photos for EHC2 here .

So , do I receive a thank you or what :thumbup:

;)

:beerchug::hug::yourock::high5::thanks::kiss3:

How's this :) I need to get my hands on one of those manuals...dragging the laptop around the engine bay scares me sometimes!

yeah but if things get serious between you I recommend placing a plank across your buttocks to prevent you falling in and dog tags around your feet for identification if the plank fails .:thumbup:

NOW THAT IS THE BEST HELP I GOT EVER THANK YOU SO MUCH FOR TAKING THE TIME DUDE NOW I KNOW EXACTLY WHERE IT IS NOW! SWEEEEEEEEEEET! YOURE AWESOME :)

Well guess what guys, i opened that compartment up, and its i don't see it in there, there is a parking module there and a small relay and there is also one emply plug with part number 1382566 but the EHC module is NOT there :( i am so sad about it, i was so excited to find it....

Are those instructions above for a 4.6 by any chance? Or is it possible that that module is somewhere by the pressure accumulator in my car?

I had to study the manual a bit more , just a wee bit mind , it says 2002 onward EHC2 module is behind glove box . that is EHC2 for cars with front and rear air .
