As the BMW E46 ages, owners often look for parts for cooling, oil, steering, suspension and transmission maintenance. We offer popular E46 parts such as engine oil filler caps, VANOS oil lines, power steering reservoirs and suspension bushings.

E46 covers 3 Series 1999-2006 (sedan, coupe, touring, convertible, M3) with several engine codes (M52TU, M54, S54). Each page lists OE part numbers, a fitment table and photos. Unsure which fits your car? Contact Us via Inbox.

A common cause: worn rear trailing arm bushings (RTAB), a known E46 weak point that lets rear toe shift under load, causing clunks and uneven tire wear. An adjustable bracket kit locks it in place. You're welcome to browse our Suspension & Shock Absorbers collection for options.

This could be related to the VANOS system — on E46 6-cylinder engines, the factory oil supply line can age over time and lose pressure, which sometimes causes a rattle on cold start. Fitting an upgraded line may help restore proper oil flow. You might find it helpful to take a look at our Vanos Oil Supply Line Hose

This could be related to the power steering reservoir — on the E46, the plastic tank is known to become brittle and crack with age, which can lead to fluid seeping out. Fitting an upgraded reservoir may help resolve this. Feel free to take a look at our Power Steering Reservoir Upgrade Kit.
