The complete E46 reference
Generation-wide context, followed by specifications for the selected sedan body.
The E46 is the fourth generation of the BMW 3 Series. It replaced the E36 and was introduced first as a four-door sedan, then expanded into Touring, coupe, cabriolet and Compact body styles. Across the range it combined longitudinal engines, rear-wheel drive and a multi-link rear axle with a broader safety and equipment package than the outgoing generation.
This page treats a body style as a separate catalog record while keeping generation-wide engineering, history and ownership knowledge in one place. Model names, power outputs and standard equipment varied by market and model year, so the tables identify representative European specifications and call out notable regional differences where they matter.
The five bodies followed different production and revision calendars. Sedan and Touring received their principal update before the regular coupe and cabriolet, Compact had its own short lifecycle, and M3 retained a separate shell, S54 powertrain and chassis specification. All-wheel-drive xi and xd derivatives were limited to sedan and Touring, while CSL, CS and North American ZHP cars require their own market and mechanical scope.

Transmissions & driven wheels
The gearbox cannot be identified reliably by “manual” or “automatic” alone; engine, market and production date determine the unit.
6-speed manual
Used by M3 from launch and introduced to selected high-output petrol and diesel models later in production, including 330 and 325ti/320td applications in some markets.
5-speed automatic
Steptronic torque-converter automatics were offered across much of the range. Unit family and calibration differ between engine, production date and market.
SMG / SSG
An automated single-clutch gearbox was offered on selected regular models; M3 used the faster, M-specific six-speed SMG II system as an alternative to the manual.
Rear-wheel drive
The default E46 layout: longitudinal engine, gearbox behind it and a separate rear differential. Final-drive ratios vary substantially by engine and transmission.
xi / xd all-wheel drive
Sedan and Touring could be ordered with a permanent all-wheel-drive system. The front driveline changes suspension, oil-pan and service parts, so it must be treated as its own mechanical branch.
Chassis, brakes & safety
The base architecture is shared, but brake sizes, springs, steering, all-wheel-drive hardware and M components remain model-specific.
Front axle & steering
- MacPherson-strut front suspension
- Aluminium lower control arms on core models
- Hydraulic rack-and-pinion steering
- Model-year and package-specific steering ratios
Rear axle
- Independent multi-link rear suspension
- Rear subframe carried by the floor structure
- Separate springs and dampers on standard bodies
- M3 receives M-specific geometry, track and differential
Brakes & stability
- Four-wheel disc brakes; diameter depends on engine
- ABS with electronic brake-force distribution
- ASC+T on early cars; DSC progressively standardised
- Tyre-pressure monitoring on selected later cars/markets
Body & safety
- Front and side airbags; head-protection coverage depends on body and market
- Belt pretensioners and load limiters
- ISOFIX availability varies by model year
- Cabriolet adds structural reinforcement and rollover protection
Production timeline & facelifts
E46 did not change on one universal facelift date. Sedan/Touring, regular two-doors, Compact and M3 follow different revision paths.
Production begins
Series production of the E46/4 sedan starts late in the year ahead of the 1998 market launch.
Sedan launch
The fourth-generation 3 Series launches with four- and six-cylinder petrol engines and the direct-injection 320d.
The family expands
Coupe and Touring join the range; the six-cylinder 330d introduces common-rail diesel performance to the generation.
Cabriolet, M54 and M3
The open body arrives, 325/330 M54 models replace 323/328 derivatives, and the E46 M3 coupe enters production.
Compact and Valvetronic
The E46/5 Compact completes the five-body family. 316ti debuts production Valvetronic; M3 Cabriolet and SMG II follow. Sedan/Touring receive their main update.
Coupe/Cabriolet facelift
Two-door regular models gain revised lights and body details; updated diesels and wider six-speed-manual availability appear. M3 CSL is produced.
Late-series development
320Cd Cabriolet becomes BMW’s first open-top diesel. Compact receives detail updates; market-specific editions continue.
Successor transition
E90 replaces the sedan first. Touring, Compact, coupe, cabriolet and M3 end on different schedules, with final E46 derivatives continuing into 2006.
M3, CSL and notable derivatives
These variants can look similar to option-package cars but differ materially in engine, chassis, production identity or market specification.
M3 Coupe / Cabriolet
E46 M3S54B32 engine, wider tracks and bodywork, M Variable Differential Lock, M-specific brakes and suspension. Offered with six-speed manual or SMG II.
M3 CSL
Coupe Sport LeichtbauLimited-production coupe with 360 PS, carbon-fibre roof and intake components, reduced mass, revised aerodynamics, suspension and bespoke Michelin tyres.
M3 CS / Competition Package
ZCP / CSLate M3 package combining quicker steering, larger brakes, CSL-style wheels and selected chassis/equipment changes without the CSL’s full weight reduction.
330i ZHP
Performance PackageNorth American performance package for sedan, coupe and cabriolet with revised M54 calibration, shorter final drive, suspension, body and interior changes.
330i Club Sport
Club SportSelected European-market coupe derivative with M Sport body treatment, deleted comfort equipment and minor weight reduction; specification varies by country.
Alpina B3 / D3
E46-basedAlpina’s petrol and diesel interpretations used their own engines, chassis tuning, wheels, trim and production identity and should be catalogued separately from factory BMW trims.
Interior, technology & option structure
Standard equipment changed by country and year. A VIN/build-sheet lookup is the reliable way to describe a specific car.
Cabin & comfort
- Manual or electric seats; heating and memory by market
- Automatic climate control
- Rain sensor and automatic headlamps on later/equipped cars
- Cruise control and multifunction steering wheel
- Power glass sunroof; panoramic-style roof on Touring was not offered
Audio & navigation
- Business and Professional radio variants
- Cassette or single-CD head units depending year
- Harman Kardon sound system
- 4:3 or later 16:9 navigation display
- CD changer, telephone preparation and BMW Assist by market
Exterior & chassis packages
- Sport suspension and wheel packages
- M Sport / M Aerodynamic body equipment
- Xenon then bi-xenon headlamps on later applications
- Roof rails and load systems for Touring
- Factory hardtop option for Cabriolet
Trim identification
- Equipment is encoded by option numbers, not reliably inferred from exterior appearance
- Seats, steering wheels and bumpers are commonly retrofitted
- Build sheet and VIN-specific parts catalogue should confirm original specification
- US, EU, UK, Japan and other markets use different standard-equipment bundles
Inspection, known weak points & service planning
A release-quality catalog should help identify risk without presenting forum anecdotes as universal defects. Use this as a structured inspection list.
Priority inspection
- Confirm open safety recalls and airbag campaigns by VIN with BMW or the national authority.
- Inspect the rear-axle carrier mounting area and surrounding floor for cracks, previous reinforcement or repair.
- Pressure-test the cooling system and inspect expansion tank, radiator necks, thermostat housing, water pump and hoses.
- Check corrosion at jacking points, rear arches, sill ends, boot-lid edges, fuel-filler area and Touring tailgate seams.
Engine & driveline
- Check cold-start behaviour, crankcase ventilation, oil-filter-housing and valve-cover leaks on petrol engines.
- On M54, inspect DISA operation and intake boots; on M52TU/M54 assess VANOS seals and vacuum leaks.
- On diesels, verify turbo control, injector correction, crankcase breather service and swirl-flap strategy where fitted.
- Check clutch, dual-mass flywheel, gearbox shifts, differential noise, propshaft coupling and centre support bearing.
Chassis, body & electronics
- Inspect front control-arm ball joints/bushes, rear trailing-arm bushes, dampers, springs and top mounts.
- Test every window regulator, central lock, mirror, climate-control function, instrument display and audio/navigation unit.
- Check Cabriolet roof operation and drains; check Touring tailgate wiring, rear wiper and glass release.
- Confirm ABS/DSC warning lamps complete their self-test and scan all modules, not only the engine ECU.
| Item | Interval / trigger | Catalog note |
|---|---|---|
| Engine oil & filter | Condition-based; many owners shorten to 10,000–15,000 km / annual | Use the oil approval and viscosity specified for the engine and climate. |
| Brake fluid | Every 2 years | BMW’s time-based service indicator includes brake fluid. |
| Coolant | Age/condition based; inspect annually | Cooling-system plastic condition matters more than coolant colour alone. |
| Manual gearbox & differential | No universal factory service interval | For preservation, document fluid specification and service history rather than relying on ‘lifetime’ wording. |
| Automatic transmission | Unit-specific | Identify the exact ZF/GM transmission before selecting fluid, filter and procedure. |
| Air, cabin and fuel filters | Inspection/service dependent | Fuel-filter configuration differs between petrol, diesel and market. |
| Spark plugs / glow system | Engine-specific | Use engine code and production date; intervals and plug types differ. |
| Valve clearance | M3 S54 only | S54 uses mechanical valve adjustment; regular E46 petrol engines use hydraulic compensation. |
How to identify the exact car
The badge, body shape and registration year are not enough for accurate parts, equipment or technical data.
- VIN
- The 17-character VIN identifies manufacturer, model/engine family, restraint system, market and serial number. Decode it, then confirm against the physical build plate and stamped identifiers.
- Build date
- Model year is not enough for parts. E46 revisions often split by month, especially lights, control modules, suspension, airbags, navigation and engine-management components.
- Body code
- E46/4 sedan, E46/3 Touring, E46/2 coupe, E46/2C cabriolet and E46/5 Compact. M3 uses the coupe/cabriolet body family but has its own parts and chassis branches.
- Engine code
- Badge alone cannot determine the engine: 316, 318, 320, 325 and 330 names span multiple engines. Confirm the engine designation, emissions version and production date.
- Option codes
- Factory equipment is recorded as SA option codes. Use a build sheet before describing a car as Sport, M Sport, Individual, Harman Kardon, xenon or navigation equipped.
- Parts compatibility
- Separate left/right-hand drive, petrol/diesel, RWD/AWD, pre/post-facelift and M/non-M. Visual similarity is not proof that a part interchanges.
