BMW Fuel Filters
BMW E88 Fuel Filters
The first place to look at for fuel supply and lean condition faults is the fuel filter. It's not hard for contaminants, dirt, and dust to find its way into your fuel system. Even rust can form in the tanks of some cars and that debris gets transferred through the system until eventually reaching the filter. There's nothing wrong with the system - the filter is doing exactly what it's supposed to do! But regular replacement of the fuel filter will ensure plenty of fuel is available for the engine to make power with. Is there a power gain from a fuel filter? No, but there is power restoration. The fuel filter is easily accessible on most cars and replacement is straight forward.

This Genuine BMW fuel filter/fuel pressure regulator is located in the fuel tank on the left hand side. BMW officially claims these are "lifetime"units, but in practice We recommend preventative replacement of the fuel filter at 60-80,000 mile intervals. Often a clogged fuel filter can cause any number of driveability issues including stalling and cold start problems. br>

We recommend preventative replacement of the fuel filter at 80-100,000 mile intervals. BMW called them "lifetime" but there's no question that any filter is going to get saturated with debris and dirt and its performance will suffer. The dirty filter can cause E90/E92 running issues like stalling, poor performance, rough running, chugging. We have replaced these filters in cars with 130,000+ miles and found the original filter was long overdue for replacement. These cars had the above driveability problems but had no fault codes or DTCs (which led to other shops making poor service recommendations). So we recommend having this done at the 80-100,000 mile mark as a scheduled maintenance item. There's no harm or downside to replacing it before it's completely clogged and your engine starts to suffer. The fuel filter is located on the driver's side and includes two new large o-rings for the lock rings. The crossover lines to the fuel pump on the passenger side are included as well. We recommend new steel lock rings for the filter and the pump, especially on cars located in the Rust Belt or in salty climates. On really high mileage cars it would be a good idea to also replace the fuel pump as preventative maintenance since the job is essentially the same. The E9X fuel filter replacement is not complex but access can be difficult and you're dealing with potentially fragile plastic so amateurs may want to leave this to a professional technician.
Not for N51 SULEV engines in 128i/328i/328xi. Check with your BMW dealer on SULEV parts that may be covered under an extended warranty.
