Locating the oil filter on a 2019 BMW 430i is a fundamental step for any owner performing their own maintenance. While the engine is a marvel of German engineering, accessing the filter requires a specific procedure that differs significantly from older vehicle models. This guide provides a clear, step-by-step walkthrough to help you find the component efficiently and safely.
Understanding the Drain and Filter Process
The 2019 BMW 430i utilizes a unique oil drain plug and filter configuration that prioritizes a controlled and clean oil change. Unlike vehicles with top-mounted filters, the filter element on this model is located near the bottom of the engine block. This design necessitates draining the old oil first before the filter can be safely accessed, ensuring that messy oil does not drip down during the replacement process.
Primary Location: Beneath the Engine
To answer the core question of where the 2019 BMW 430i oil filter location is, you must look downward. The oil filter is situated on the passenger side of the engine, positioned close to the oil pan. It is housed within a small, cylindrical metal casing that is secured by a large rubber gasket. You will need to crawl underneath the vehicle or drive it onto a lift to get a clear view of this assembly.
Identifying the Oil Drain Plug
Before reaching the filter, you must locate the oil drain plug, which is found at the very bottom of the oil pan on the driver’s side. This plug is a large hex bolt that secures the pan. Removing this plug allows the old oil to drain completely into a catch pan, creating a safer workspace for when you remove the filter assembly.
Accessing the Filter Assembly
Once the oil has finished draining, you can turn your attention to the filter. The filter is not directly screwed into the oil pan drain hole; instead, it is part of a larger unit that connects to the engine block via a large, circular rubber gasket. You will need to locate the two 19mm bolts that secure this filter housing to the engine.
Tools Required for the Job
Attempting to remove the filter without the correct tools will result in frustration and potential damage. You will need a 19mm socket and wrench to loosen the two bolts holding the filter housing in place. Additionally, a oil filter wrench is unnecessary for the canister itself, but a drain pan long enough to fit under the housing is essential to catch the residual oil that will spill out when the bolts are removed.
| Specification | Detail |
|---|---|
| Oil Filter Part Number | BMW LL-01 01 FD 71139072794 |
| Oil Filter Housing Bolts | 19mm (Two Bolts) |
| Oil Capacity | Approximately 10.2 quarts (including filter) |
| Recommended Oil Type | 5W-30 or 0W-30 (BMW Long-life Specification) |
Final Steps and Considerations
After removing the two 19mm bolts, the entire filter housing, including the old filter cartridge inside, will drop into the pan. Be prepared for a mess, as this unit contains a significant amount of used oil. Before installing the new filter, ensure the new rubber gasket on the replacement housing is lubricated with fresh oil to guarantee a proper seal. Reinstalling the housing requires tightening the two 19mm bolts to the manufacturer's specifications to avoid stripping the threads.
