BMW 7 Series owners manuals
- Owners have reported problems with the engine misfiring causing it to idle badly, with the rev gauge jumping up and down instead of remaining at a constant rate leading in some cases to engine cutting out.
- Issues related to electric windows making a squealing sound whenever the windows are open/close. This means that the window regulator is breaking.
- Air conditioning not blowing out ice-cold air in the coldest settings caused by a flaw with the condenser.
- Door lock failure caused by door lock motors or a flat battery in the key fob.
The BMW 7 Series is a full-size luxury vehicle manufactured by the German maker BMW since 1977 and it is the replacement to the BMW E3 "New Six". Currently, sixth generations are available.
The 7 Series is BMW's flagship vehicle and is solely available in a sedan variant. It includes technologies and exterior design ideas before they trickle down to other BMW models.
The initial generation of the 7 Series was equipped by straight-6 petrol engines, the following generations have been equipped by inline-4, straight-6, V8 and V12 engines with natural aspiration and turbocharging. As 1995, diesel engines remained optional in the 7 Series.
BMW has not built an M model for the 7 Series, unlike the 3 Series and 5 Series sedans. Nevertheless, in 2014 an "M Performance" package became available for the 7 Series.
The new 7 Series engines range, from the 740i's 320-hp turbocharged inline-six to the M760i's 601-hp twin-turbo V-12 paired with a slick-shifting eight-speed automatic transmission. The xDrive with for all-wheel drive is optional on the 740i but standard on the rest of the series.
