BMW 320d, 330d 2002 Workshop Manual

If you are tearing into an E46 320d or 330d, you have two options: chase aftermarket wiring diagrams that show the wrong pinouts, or use the actual factory documentation. This manual is the latter. It covers the M47 four-cylinder and M57 six-cylinder diesel engines from April 1998 through October 2001, published in 2002 by E.T.A.I. and ANETO-ETAI. BMW 320d, 330d 2002 Workshop Manual means you get the same procedures a dealer tech would follow — in 160 pages of direct, step-by-step instructions. No guessing, no generic illustrations. You get the exact torque specs, the exact clearance limits, and the exact diagnostic flowcharts.

I have seen more than one shop waste an afternoon because some online PDF told them the intake camshaft torque was 10 Nm low. That is a head gasket leak waiting to happen. This manual gives you the real numbers — and it does not leave out the steps that most aftermarket books skip, like the specific order for loosening the cylinder head bolts on the M47. Page 1 carries a warning that this is meant for professionals, which means it assumes you know how to use a torque wrench. If you don’t, buy one before you open the hood.

M47 4-Cylinder Engine – Timing Chain and Cylinder Head

The first chapter covers the M47 motor. It starts with torque values for every fastener on the injection pump, clutch, oil pump, and cylinder head. Then it walks through removal and installation of the timing chain, including the calibration (caliado) procedure that sets the cam and crank timing. If you skip the marking step, you will bend valves. The manual also includes the autodiagnóstico (self-diagnosis) for the engine management system, a fault code list, and wiring diagrams. You need the wiring diagrams to trace the common injector driver faults on these cars.

M57 6-Cylinder Engine – High-Pressure Injection System

The six-cylinder M57 gets its own chapter with its own set of torque values and technical data. This engine uses a high-pressure common-rail injection pump. The manual dedicates a full section to precautions for the fuel circuit — diesel will ruin your skin and your fire insurance. It then shows you how to remove and install that high-pressure pump without trashing the seals. There is also a control check for the cylinder heads, because these engines are known for cracking between valves if overheated.

Does This Manual Cover the Fuel System?

Yes, exactly. The M47 chapter includes removal and installation of the injection pump plus a check for fuel supply pressure. The M57 chapter covers the high-pressure pump and the entire common-rail system. Both have wiring diagrams and fault code lists for the engine management diagnostics. No aftermarket manual will give you the correct peak-pressure specs for the M57 — this one does, but you will have to find them on the pages yourself; I am not your pocket-protector reference.

Clutch and Transmission – Torque Values You Cannot Fake

Chapter three covers the clutch: replacement of the mechanism, release cylinder, bearing, and dual-mass flywheel. Page numbers? You don’t need them if you read the chapter. What you need is the flywheel bolt torque pattern — cross-tighten in stages or the flywheel warps. The manual gives that. Chapters four and five cover the manual and automatic transmissions. Same deal: removal, installation, and the correct fluid fill procedure for the automatic. Again, torque values for every bell housing bolt.

Why Factory Specs Beat Aftermarket Documents

Aftermarket manuals are written by people who read the factory manual and then summarized it — with errors. I have seen an aftermarket wiring diagram swap the ground and power for the DSC accelerometer. That will cost you a control module. This manual comes from the original French publisher E.T.A.I., authorized by BMW for the Spanish edition in 2002. It is a direct reproduction of the factory data, including the illustration style and the exact note about injection pump timing. You can trust it because it is not a reprint of a copy of a scan. It is the document you need to keep your 320d or 330d on the road without chasing ghosts.

7 Systems Covered – From Steering to ABS

The manual covers eleven chapters total. After the engines and transmissions, you get the final drive (chapter six), steering (chapter seven), front suspension (chapter eight), rear suspension (chapter nine), brakes including ABS (chapter ten), and electrical equipment (chapter eleven). The brake chapter includes the procedure to unlock the brake booster pump, replace rear pads, bleed the system, and replace wheel speed sensors and the DSC accelerometer. Electrical chapter covers alternator, starter, instrument cluster, airbag module.

One quick note: the manual is written in Spanish. If you cannot read technical Spanish, you will struggle. The drawings are clear, but the instructions are all in Spanish. That is the only language we have for this edition. Consider that before you buy.

Does this manual cover the automatic transmission fluid change procedure?

Yes. Chapter five includes the fill and purge (Llenado y purgado del circuito) steps for the automatic transmission. It also covers replacing the suction filter.

What year and models are covered?

BMW 320d and 330d with E46 body, built from April 1998 to October 2001.

Are wiring diagrams included?

Yes, both the M47 and M57 chapters have wiring diagrams (Esquemas eléctricos). The brake chapter also includes a legend for the electrical diagrams. This is crucial for diagnosing ABS and DSC faults, especially after replacing a wheel speed sensor or the DSC hydraulic unit. Without the correct diagram, you risk shorting the control module. The manual shows pin colors and connector locations.

Is this manual in English?

No. The Spanish edition from 2002 is the only version we offer. All text is in Spanish.

If you are working on a 320d or 330d with the M47 or M57 engine, and you need the actual factory procedure for timing the camshaft, torquing the cylinder head, or bleeding the brakes, this is the document to have.
