EGR 'quality enhancement'
Had BMW perform an interim oil change on my 320D this morning & was advised that my car was due an EGR 'quality enhancement' whatever that is....
Apparently they run a software check to ensure its operating within certain parameters & if not, they'll replace the EGR.
To be honest, I don't trust a word they say & I refused the work. Got visions of them screwing my car up trying to rectify their dishonesty with emissions a la Volkswagen.
Anyone had this done & noticed anything different??
