BMW M3 Forum (E90 E92) - View Single Post - DIY: Replace Fuel Tank Breather Valve (Fix for bouncing idle at fuel station)

Does anyone know if there are any negative side effects to the car if you have this problem and don't replace the valve? As far as I know, it's only the bouncing RPMs for a minute or so after you fill up gas. Can it do some potential damage?
