Here’s a detailed ''empty engine'' (bare long-block) description for the 1.8 TFSI engine (engine code CJE / variation CJEB) used in the Audi A4 B8.5 (1.8 litre).

You can use this as a checklist or spec sheet when sourcing a unit.

Engine summary & compatibility

• Engine code: CJE (also seen CJEB) — a 1.8 TFSI petrol engine of 1,798 cc (1.8 litre) displacement.  
• Fitment: For Audi A4 (B8/B8.5 series) and also A5 in some markets.  
• Power output: in many applications ~125 kW (≈ 170 hp) and torque ~320 Nm for the later version.  
• Bore × stroke: 82.5 mm × 84.1 mm.  
• Compression ratio: 9.6 : 1.  
• Engine layout: Inline-4 (I4), turbocharged + intercooler, direct injection + manifold injection in some versions.  
• Emission / management: Euro5 in many cases for the later versions.  

What ''empty/bare engine'' means & what to expect

When someone refers to an ''empty'' or ''bare'' engine, typically they mean the long‐block (block + head + crank, pistons & rings, typically without many ancillaries such as turbo, fuel rail, wiring harness, maybe without the intake manifold, etc). So for a CJE/CJEB engine you should check:

What is usually included:

• Engine block (cylinder block)
• Cylinder head(s) (double overhead cam head in this case)
• Crankshaft, pistons, connecting rods (internal components)
• Timing chain set (depending on condition)
• Valvetrain, cams (DOHC)
• Possibly oil pan, front cover, maybe turbo mounting flange, etc (depends seller)

What may not be included (you must check):

• Turbocharger & intercooler plumbing
• Intake manifold
• Exhaust manifold / downpipe
• Fuel injection system (rails, injectors)
• Wiring harness / sensors
• Oil pump or ancillary pumps (sometimes included, sometimes not)
• Accessories (alternator, A/C compressor, power steering pump)
• ECU or engine management module

So when you’re comparing, confirm the ''contents of delivery'' from the seller (some list ''bare engine without ancillaries or turbo'' etc). For example a listing says ''Bare engine (without attached parts) or a complete engine (depending on your choice)''. 

Things to check / compatibility issues

Fitment & code match:

• Make sure the engine code (CJE or CJEB) matches your car’s VIN/engine bay plate. A mismatch can lead to wiring, ECU or mounting problems.
• Confirm your car is the 1.8 TFSI 1798 cc version and not a different engine. For example the B8 series had 1.8, 2.0 TFSI, etc.  
• Check if your vehicle is FWD or Quattro (4WD) – some variants differ in mounting or ancillary parts.

Condition & known issues:

• Some 1.8 TFSI engines (and more so 2.0 TFSI) from this era had excessive oil consumption issues (due to piston rings / design) in certain markets.  
• Timing chain tensioner / chain guide failures can happen – check service history.
• Check for signs of turbo / boost damage especially if the unit is sold ''used''. The long‐block may be fine but ancillary turbo gear may be worn.
• For a ''bare'' long‐block, you will need to ensure you have all correct fittings / sensors / ancillaries from donor car or purchase new.

Supply & shipping considerations:

• If you’re importing or sourcing from abroad, check shipping/clearance/compatibility with Malaysian register (if in KL).
• Ensure the seller lists exactly what ''bare'' includes and what is omitted.
• Warranty – many used engine sellers offer e.g. 12 months or certain km limits. Example: one listing offers 12 months warranty.  

Typical specs summary (for this engine in your car context)

• Compression: 9.6 : 1
• Valvetrain: DOHC, 16 valves
• Turbocharged & intercooled, petrol direct injection + manifold injection
• Engine code: CJE / CJEB (depending on variant)
