What precisely is E46? Understanding of what a E code is going to be the first step in understanding the terminology E46. BMW began marking their versions by using an E
designation in 1968 beginning with the E9 and E3. The sedan was the E3 and the coupe was the E9 E designations are given by the manufacturer for unique body style vehicles. Oftentimes these versions are different years but essentially are the same car.
BMW will design the same model for a number of years with only minor changes. This is especially beneficial since it allows BMW to use similar components for a span of years. Look at the E46 for instance. The E46 started manufacturing in 1998 as a sedan and 1999 as a 2-door. Manufacturing continued for the 4-door till 2005 and 2006 for the coupe and M3. By and large, all of these cars were identical and many parts are shared.
And although most of the components are equivalent, you can also find a few systems that the parts vary like options and engines. Things such as the suspension or dash for instance are the same throughout every model excluding the improved suspension on the Sport package and m3 models. With the exception of the M3 or sport package, 70% of the full 3-series production from 98-05 have totally interchangeable suspension. The same sway bars and links and the same struts and shocks.
Sometimes, options such as seats, door locks and the radio usually are shared amongst the model range. A power steering pump from an 2001 325i will also fit a 2005 330ci. So with the window switches, they will fit every E46. The body components share these traits also. Except for M3 and coupes, all sedans share the same doors, fenders, trunk and hood. Various components fit all E46 but different years like the bumpers. Many may fit coupe and 4-door models although only in certain years.
Computer and safety items stay the same through E46's production. With the exclusion of program updates, many computer units have stayed the same in particular units such as the ABS controller or Airbag computer. It is sometimes vital to update or re-design an item on account of a flaw or design malfunction. This is called superceding.
Superseding components is critical when it's got an excessive malfunction rate. A excellent instance is the steering pressure pumps. They have been modified and improved nearly 10 times simply because there are many issues. The initial types ended up too weak to manage the stresses of the steering system and would overheat on account of insufficient fluid moved through the interior blade. A lot of components, such as the E46 330ci engine parts have never been updated.
The most common components replaced on the E46 are engine cooling parts. Once you obtain an E46, you may well replace a thermostat housing and water pump no less than once. Parts such as the radiator and coolant tank are comprised of an ABS plastic that has a propensity for getting brittle in time. Other than a handful of other parts, the BMW E46 is pretty dependable and possibly one of the finest automobiles BMW has ever crafted. Sales numbers verify the E46 the most winning BMW ever.
