840Ci Airbag Ecu

[pony tony]

hi there fellow beemers. not been on the site for a while,must say looking good since i last looked. great looking site. i'm hoping someone can help. i've bought a new airbag ecu. problem is i can't find where the ecu is situated. i've got a workshop manual on disk. it says the ecu is under the passenger side dashboard. looked under there and all i can see is the body control modules,no sign of the ecu.if anyone can help it would be very helpful. look forward to any help.thanks.

Should be there behind glovebox... If not then locate the engine ECU (usually under bonnet on near-side behind suspension top), there maybe 3 - 4 modules in there ;)
