Diesel Fuel Filter & Heater Assembly, BMW - E90 335d

This is the fuel filter and heater assembly for the E90 335d. The filter should be replaced as part of a regular maintenance program. A clogged fuel filter will usually cause hard starting, drivability issues, and even lean condition fault codes. It could also cause more severe damage to fuel injectors, fuel pump, or even internal engine damage if fuel shortage issues are not solved quickly. A fuel filter is cheap insurance and not to be overlooked!

The heater thins Diesel fuel in colder temps where it can become too thick to flow through the system. Replacing the filter can be done independently from the heater but if you suspect your heater is not functioning this is a ready-to-install assembly.

This is a Genuine BMW Diesel filter and heater with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
