E90 BMW 3 Series Sedan (2005-2012) Buyer’s Guide
Thinking of buying a used E90-generation BMW 3 Series sedan? Here’s everything you need to know, including the derivatives available in South Africa, what to look out for and what you can expect to pay…
Succeeding the acclaimed E46, BMW’s E90-generation 3 Series sedan was a model of numerous firsts and a few lasts. For instance, the range included the first turbocharged petrol 3 Series variant (in the form of the 335i), while this generation also saw the introduction of the iDrive operating system and the somewhat controversial – thanks to their comfort-robbing properties – runflat tyres.
Meanwhile, the M3 of this era was the first and only iteration to employ a V8 engine. Of course, the broader E9X family was also the last 3 Series range to include the coupé and convertible body styles (which subsequently split to become the F32 and F33, respectively, in the first-generation 4 Series line-up), as well as the last to boast a high-revving, naturally aspirated straight-6 petrol engine.
The E90 was the only M3 to boast a V8 engine.
Though it was a little larger than its predecessor, the conservatively styled fifth-generation 3 Series sedan – which was no longer the entry point to the BMW range considering the original 1 Series launched in 2004 (hence the lack of a 316i or 318i in this series in SA) – was again an out-and-out driver’s car, boasting rear-wheel drive, near-perfect axle load distribution, a sophisticated suspension set-up and a range of characterful 4- and 6-cylinder powerplants (plus that V8) in petrol and diesel flavours.
While the E9X line-up also included the E91 Touring (estate), E92 Coupé and E93 Convertible (the latter featuring a retractable hardtop), here we’re going to focus on the saloon – which was, of course, produced at Plant Rosslyn in South Africa for both the local and export markets. Still, much of this discussion will apply to the other body styles as well owing to the wide sharing of powertrains and other components.
When all was said and done, BMW had built around 350 000 units of the E90-generation 3 Series sedan at Plant Rosslyn, with production running from 2005 to 2012 (around the same time the company stopped building the E91 Touring). Interestingly, the Munich-based firm continued manufacturing the E92 Coupé and E93 Convertible at other sites into 2013.
BMW 3 Series Sedan (E90) model line-up
The first official photographs of the E90 went public late in 2004.
Though the first official images were released in November 2004, the full unveiling of the E90-generation 3 Series took place only in March 2005 at the Geneva International Motor Show. A little over a year later, the German firm’s compact executive saloon was named the World Car of the Year for 2006.
The fifth-generation 3 Series hit the market in South Africa in May 2005, with the initial local line-up featuring four engine options and the choice between a 6-speed manual gearbox and a ZF-sourced automatic transmission with the same number of cogs. The following powertrain variants were offered at launch, each available with either of the gearboxes options:
- 320i: 2.0-litre, 4-cylinder petrol (110 kW/200 Nm)
- 320d: 2.0-litre, 4-cylinder turbodiesel (115 kW/330 Nm)
- 325i: 2.5-litre, straight-6 petrol (160 kW/250 Nm)
- 330i: 3.0-litre, straight-6 petrol (190 kW/300 Nm)
In November 2005, the local sedan line-up expanded with the arrival of the 330d, which BMW at the time described as the “flag bearer for diesel in the 3 Series range”. Indeed, it was the most powerful oil-burner yet for a 3 Series model, offering 160 kW and 480 Nm from its 3.0-litre straight-6 engine.
At the same time, the Bavarian company added the 323i and 320i Start to the local range. The 323i slotted in below the 325i, employing a 2.5-litre 6-cylinder petrol unit generating 130 kW and 230 Nm, while the 320i Start was introduced as a fresh entry-level model (but was mechanically identical to the slightly higher-specced 320i). BMW also used this opportunity to roll out a new Sport specification, which was available in conjunction with any engine derivative and added features such as sports suspension, an aerodynamics package, exclusive light-alloy wheels, sports seats and an M leather steering wheel.
The 335i briefly played the role of flagship, before the M3 touched down.
In April 2006, the base Start specification was (seemingly briefly) extended to the 320d, before the 335i slotted in at the summit of the 3 Series portfolio in June 2007. Introducing forced induction to the range, the 335i employed a twin-turbo 3.0-litre straight-6 petrol unit churning out 225 kW and 400 Nm, offered in conjunction with a new, faster-shifting version of the 6-speed automatic transmission (or, indeed, the manual cog-swapper). BMW claimed the 335i could complete the 0-100 kph sprint in 5.5 seconds.
Around the same time, two other 6-cylinder saloon models gained an increase in power and torque thanks to “a series of engine management and component changes”. The 330i’s peak outputs improved to 200 kW and 315 Nm, while the 323i’s figures grew to 140 kW and 235 Nm (both engines thus gaining 10 kW and 15 Nm). A few months later, the 320d also quietly scored some extra oomph for new maximum figures of 125 kW and 340 Nm, while the 320i moved to 115 kW.
The V8-powered M3 saloon arrived in SA at the end of the first quarter of 2008.
In March 2008, the M3 sedan (with a front-end design matching that of the coupé) finally touched down, ditching the 6-cylinder layout used by the preceding model generations. Yes, the E90-generation M3 featured a 4.0-litre V8 engine developing 309 kW and 400 Nm – fed to the rear axle via a 6-speed manual gearbox – and revving to 8 400 rpm. The obligatory sprint to three figures took a claimed 4.9 seconds, while top speed was electronically limited to 250 kph. A 7-speed double-clutch transmission (M-DCT) arrived towards the middle of 2008, cutting the 0-100 kph sprint time to a claimed 4.6 seconds.
BMW also rolled out a limited 3 Series Sport Edition, with only 300 units (produced between June and September 2008) set aside for the South African market. The Sport Edition was set apart by items such as the full M Sports Package, 18-inch WTCC-inspired wheels, “Sport Edition” embossing on the leather sport seats, branded aluminium door sills and a handful of extra options. At the same time, BMW took a decision to no longer restrict power and torque on diesel models sold locally. The 330d thus enjoyed new outputs of 170 kW and 500 Nm, with the 320d’s maximum figures improving to 130 kW and 350 Nm.
The BMW 3 Series (E90) receives a facelift
In the final quarter of 2008, the refreshed 3 Series sedan launched in SA.
Around October 2008, the facelifted or LCI (Life Cycle Impulse) version of the E90-generation 3 Series hit the local market. Featuring fresh exterior styling and an updated interior (including a new generation of iDrive), the upgraded sedan’s powertrain line-up remained largely in place and didn’t benefit from the raft of engine updates offered in Europe. However, a fresh version of the 330d’s 3.0-litre straight-6 turbodiesel mill debuted, conjuring up 180 kW and 520 Nm, while also boasting improved efficiency.
Towards the middle of 2010, the 320d was subjected to another engine adjustment, with its outputs growing to 135 kW and 380 Nm, while 300 units of the Dynamic Edition – available only on the 320i, 320d and 335i – were confirmed for South Africa. At the same time, the 335i switched from the twin-turbo N54 straight-6 to the twin-scroll single-turbo N55 unit (but interestingly didn’t get the option of a 7-speed DCT that became available in the likewise N55-powered 335i Coupé and 335i Convertible). Peak power and torque were unchanged, though the N55 ostensibly brought a modicum of fuel savings.
By November, the 320d, 323i, 325i and 330i (the 320i joined the party in January 2011) had gained fresh efficiency tech such as brake energy regeneration, improving fuel consumption and cutting emissions. Production of the E90 at Plant Rosslyn ended in February 2012, with the F30-generation 3 Series sedan hitting the local market the following month.
Product strengths
The E90 delivered class-leading dynamics. Pictured here is a 325i.
The driving experience: True to the 3 Series sedan models that came before it, the E90 was easily the segment’s best car for keen drivers. Facilitated by the classic front-engine, rear-wheel-drive layout, Munich’s compact saloon was a wonderfully balanced machine, offering communicative steering and excellent mid-corner poise. Though the serious grunt offered by BMW’s 6-cylinder engines – not to mention the naturally aspirated V8 of the M3 – were best for exploiting the well-sorted E90 chassis, even the 4-pot models were hardly a bore to pilot.
Broad engine range: With no fewer than eight distinct engine options – and the choice of either manual or automatic transmissions right across the range – the E90 line-up really offered something for everyone. Entry-level 4-cylinder models majoring in efficiency? Yes, in both petrol and diesel forms. Silky smooth straight-6 units, offered in increasing degrees of potency? Check (including three atmospheric petrol units, a turbodiesel mill and the turbocharged 335i). Big-hitting V8? Yip, the mighty M3 has you covered.
Improved practicality: Since the E90 sedan was larger inside and out compared with the E46, it was also considerably more practical. The fifth-generation saloon measured 4 520 mm long (an increase of 49 mm) and 1 817 millimetres wide (78 mm up), while its wheelbase grew 35 mm to 2 760 mm. Luggage capacity, meanwhile, came in at a decent 460 litres, though the original buyer had to pay extra (R3 000 in November 2008) to specify folding rear seats.
Product weaknesses
Plastics in the E90’s cabin can be prone to peeling.
Is the E90 saloon a reliable vehicle? That’s not a straightforward question to answer, largely thanks to the wide range of powerplants used in this generation. Some owners report years of trouble-free service, while others have nightmare tales (trawl the forums and you’ll find examples of such for virtually every engine). Thus, it’s wise to be as meticulous with maintenance as possible, whether you’re dealing with an atmospheric or turbocharged example. Let’s take a closer look at some of the major common issues below.
Oil-filter housing leaks: The N series of engines used in the E90 – so, all units bar the S65 mill employed by the M3 – are known to have issues with leaking oil-filter housings. While such a leak may seem little more than a driveway-staining nuisance at first, it can actually lead to complete engine failure. How? Well, oil dripping from the failing gasket can land up on the serpentine belt, quickly leading to degradation of the latter. Once the belt slips off the tensioner pulley, fragments can be sucked into the engine, quickly resulting in major damage.
Various issues with the N54: We’ve dug up various potential issues with the twin-turbocharged 3.0-litre straight-6 engine (N54) used in the pre-facelift 335i, though we suspect many would be mitigated or avoided completely with fastidious maintenance. Still, it’s worth noting reports of failures of components such as the high-pressure fuel pump, piezo-electric fuel injectors and turbocharger wastegates, as well as valve-cover oil leaks. Interestingly, the twin-scroll single-turbo N55 that was introduced with the facelift didn’t seem to suffer quite as badly.
The N54 engine used in the pre-facelift 335i has a number of potential weaknesses.
Clogged Vanos solenoids: The solenoids employed by the Vanos variable camshaft timing system (specific to petrol models) can be prone to clogging, particularly if regular oil changes have not been carried out. Once this happens, the instrument cluster may show a “check engine” light, while acceleration will be sluggish – the engine will hesitate at low revs – and fuel economy will be poor. As an aside, some SA-spec 6-cylinder models were included in a 2014 global recall that involved the checking of bolts on the Vanos unit itself.
Miscellaneous potential problems: Other fairly common potential issues include premature peeling of cabin plastics and rubber, along with electrical problems (in 2013, as many as 50 000 BMW models were recalled in South Africa after the German firm discovered a battery cable connection to a fuse box could degrade over time). While we’ve also heard of timing-chain failures on pre-facelift 320d models (using the N47 engine), these interestingly don’t appear nearly as common in South Africa as in some overseas markets.
Finally, it’s worth noting the E90 shipped standard on runflat tyres, which not only detracted from the ride quality (particularly on models with large alloys and sports suspension) but also resulted in plenty of road noise. While some owners may have switched to conventional tyres, be aware there’s no room for a spare in the luggage compartment.
What to pay?
As you might expect, the manual gearbox was not as popular as the auto in the E90.
All E9X models came with a 5-year/100 000 km maintenance plan. When scrutinising a potential purchase’s service history, pay close attention to the frequency of scheduled maintenance after that cover had elapsed. While a verifiable full service history is always a strong selling point, it’s especially important with the E9X. Buying from a particularly fastidious owner – who would have had oil changes performed more frequently than technically necessary, according to BMW’s recommendations, anyway – is a solid plan.
We should also point out the fifth-generation 3 Series was – in true German form – available with a multitude of individual extras, in conjunction with various model lines and likewise optional packages. Thus, make sure you’re comparing apples with apples when trying to decide between two or more candidates.
At the time of writing, around 79% of all E9X-generation 3 Series models listed on Cars.co.za were of the sedan variety, followed by the coupé (14%), convertible (6%) and wagon (1%). More than two-thirds featured an automatic rather than manual transmission, while petrol (77%) was the dominant fuel type and the 320i (42%) the most common powertrain. Mileage varied from 21 000 km through to 330 000 km. White (35%) was the most popular exterior paint colour, with silver (18%) and grey (14%) next.
- Below R100 000: There were a surprisingly large number of listings sporting 5-figure price tags, though most were early model-year examples with high mileage. As you might expect, the base 320i was the overwhelmingly dominant powerplant in this space.
- From R100 000 to R150 000: This is where we found the bulk of E9X stock, including plenty of facelifted (sub-100 000 km) 4-cylinder models and a small handful of 6-cylinder vehicles. It’s here that most buyers in the market for a fuel-frugal 320d saloon would likely find themselves shopping.
- From R150 000 to R200 000: While the 4-pots still dominate here, we started to see more examples of the straight-6 petrol-powered 323i, 325i and 330i, as well as the turbocharged 335i. We even found a pair of 330d sedans, each with well over 200 000 km on the clock.
- Above R200 000: Above this mark, we discovered yet more 6-cylinder models, extending all the way up to R300 000. North of that, we found only V8-powered M3 listings, though the coupé and convertible body styles were both far more prevalent than the sedan. The priciest of all was a manual-equipped 2008 M3 Coupé with 52 000 km showing on the odometer and a full service history (listed at lofty R749 000, more than the 2008 base price of R703 500).
Pick of the range?
The N52 powerplant (seen here in 325i guise) offers 6-cylinder thrills.
Considering the focus of this guide and the three-box body style’s popularity in this generation, we’re going to again concentrate on the sedan here. Though the 320i is easily the most abundant derivative on the used market and the flagship M3 the most broadly desirable, we’d argue a naturally aspirated 6-cylinder represents the sweet spot of E90 ownership, particularly for keen drivers.
The N52 engine – versions of which powered the 323i, 325i and 330i – is a less complicated and thus potentially more reliable motor than the pre-facelift 335i’s twin-turbo N54, yet is still capable of delivering genuine driver thrills. A facelifted version is best, considering the mid-cycle update included various upgrades, such as the cabin gaining an improved version of the iDrive system (where optionally specified, of course). Find a late model-year example and you’ll also benefit from ostensibly better fuel economy.
If you’re unable to resist a 335i, we’d again recommend narrowing your search to a post-facelift version since it benefits from the somewhat more trusty N55 motor. Lovers of diesel will likely struggle to find many examples of the 330d on the used market, leaving them to consider the ubiquitous 320d. Still, the latter offers a strong mix of low-down grunt and economy, though be aware the N47 engine will eventually require a vibration damper change (it’s worth checking the history to see whether this has already been done).
Verdict
We’d advise opting for a facelifted E90 if your budget permits.
Obvious and similarly mainstream alternatives to the E90 3 Series come in the form of the Mercedes-Benz C-Class saloon (W204) and the Audi A4 sedan (B8). If you’re prepared to head a little left field – and out of Germany – you’ll also have the option of the XE20-generation Lexus IS and the second-generation Volvo S60, and perhaps even late model-year versions of the admittedly underwhelming Jaguar X-Type, if you’re so inclined.
Of course, there’s little doubt the 3 Series is the best to drive of the aforementioned compact executive sedans. That fact – along with the appeal of the roundel badge – helped make the E90 one of the most popular of the seven 3 Series generations currently in existence. Interestingly, the E90 may just offer better value on the used market than its arguably more sought-after predecessor, the E46.
Shop wisely and budget for meticulous maintenance, and you’ll be rewarded with a wonderful driving experience from a model that both waved goodbye to until-then signature 3 Series ingredients and ushered in features that endure to this day.
