BMW N20 2013 Training Manual – Factory Specs for the 2.0L Turbo

BMW N20 2013 Training Manual – that’s what you need if you’re staring at a timing chain mess or a Valvetronic fault on a 2.0L BMW. This isn’t a condensed aftermarket booklet. It’s the original 134-page training document BMW issued to its own technicians. I’ve used these in my shop for years—they skip the marketing slides and give you the engineering data that matters.

Engine Components: From Block to Valvetrain

Opens with a full history of BMW AG and M engines, then drops straight into the N20’s technical data and engine identification (page 7). The manual covers the engine housing, cylinder head gasket, head cover, and oil sump in Section 2. You’ll get the factory procedure for the counterbalance shafts on page 46 and the Valvetronic system starting on page 55. Each component subsection includes design explanations and service notes—exactly the kind of detail you need before pulling that cylinder head.

Does This Manual Include Torque Specifications and Clearances?

It’s not a standalone torque chart, but the assembly sequences and tightening angles are embedded in the component chapters. For instance, the crankshaft drive section (page 27) details bearing caps and connecting rod specs. If you need the hydraulic circuit diagram for oil pressure diagnosis, it’s on page 66. That diagram alone can save you an afternoon of chasing wiring faults. You’ll still want the ISTA system for vehicle-specific torque values, but this training manual gives you the engineering context behind those numbers.

Oil Supply: Pump Control and Cooling Details

Section 3 runs from page 65 through 91. Covers the oil pump, pressure control, pressure-limiting valve, and the oil spray nozzles for piston crown cooling and chain drive. The oil monitoring section (page 86) includes the pressure/temperature sensor and level monitoring. If you’re diagnosing low oil pressure codes on an N20, start with the hydraulic circuit diagram on page 66, then check the oil pump control strategy on page 73. Aftermarket manuals skip this level of system logic—you get the full OEM training material.

7 Major Systems Detailed in the Training Manual

The TOC lists nine chapters, but the core systems break down into seven functional areas: engine components, oil supply, cooling (page 93), air intake/exhaust with TwinScroll turbocharger (page 103), vacuum system, fuel preparation including high-pressure pump and injectors, and the engine electrical system. Each chapter has its own overview diagram and component location information. For example, the intake air system section covers the hot-film air mass meter and intake manifold design. You won’t find this level of explanation in a standard repair manual.

Who Needs This: DIYers and Shop Operators Alike

If you’re a home garage guy trying to rebuild an N20 from a salvage 328i, this manual gives you the OEM assembly steps and system descriptions that aftermarket books water down. For shop owners, it’s the quick reference for training new techs on the Valvetronic adjustment or the map thermostat control. Pair it with the vehicle-specific workshop manual. If you’re working on older BMWs, check out the BMW X5 2002 Training Manual – EHC2 Air Suspension & 4.6is Specs or the BMW S85B50 2004 Training Manual – OEM Specs for the V10. For the twin-turbo six, there’s the BMW N54B3000 2009 Training Manual – Factory OEM Specs for Twin-Turbo. For background on BMW’s engine evolution, see the Automotive Industry Overview. If you need information on Manual Transmission specifics, Wikipedia’s entry is a reliable starting point.

FAQ

Is this manual specifically for the N20 engine?

Yes.

Does it include torque specs for the cylinder head?

The training manual covers disassembly and assembly procedures with tightening sequences and angles, but it’s not a standalone torque chart; you’ll cross-reference with ISTA.

Can I use this for the N20 in a 3 Series or X1?

The N20 was used across several models. The manual covers the engine itself, not vehicle-specific installation details. You’ll need the appropriate vehicle workshop manual for removal and installation.

Why should I choose the OEM training manual over aftermarket?

Aftermarket manuals often omit critical details like Valvetronic adjustment procedures, oil pump pressure control logic, and the exact chain tensioning sequence. This is the original BMW training document used to teach dealership technicians. The hydraulic circuit diagram on page 66 alone is worth the price—you won’t find that in any Chilton or Haynes manual.
