Reconditioning M70 Throttle Bodies ↗
An owner fixes rough idle and EML limp-home faults on a 750iL by removing, stripping and cleaning the electronic throttle assemblies (two on the M70) instead of paying for new ones. Removal is simple: air box, MAF and hoses off, then four small bolts per throttle.
Tools mentioned: 10 mm wrench, screwdrivers, cleaner
Owner experience on a used and an original unit; not a factory repair.
