Standard Ignition Engine Oil Pressure Switch P/N:PS649
Keep an accurate eye on engine oil pressure with the Standard Ignition Engine Oil Pressure Switch PS654. It installs as a direct-fit replacement across a wide range of BMW models, including the 2017-2020 230i, 2016-2018 330i, 2016-2018 340i, 2017-2018 430i, 2017-2020 440i, 2015-2020 740i, 2015-2019 750i, 2014-2017 i8 and 2015-2017 X1 — see the Buyer's Guide tab for the full application and engine list. This switch reads engine oil pressure and reports it to the vehicle's data monitoring system; if a failed original pressure switch is the cause of an erratic oil-pressure gauge or a false low-oil-pressure warning, this replaces it.
