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)



  • Displacement: 1,798 cc (1.8 litre)
  • Power: ~125 kW (≈ 170 hp)
  • Torque: ~320 Nm
  • Bore: 82.5 mm
  • Stroke: 84.1 mm
  • Compression: 9.6 : 1
  • Valvetrain: DOHC, 16 valves
  • Turbocharged & intercooled, petrol direct injection + manifold injection
  • Engine code: CJE / CJEB (depending on variant)
