Warnings

ADVICE AND WARNINGS TO FOLLOW BEFORE REPLACING THE TURBO

Before changing the turbocharger, it is essential to fully understand the causes that led to its failure.

The operations described below, are fundamental to avoid a second failure and consequently a warranty claim.

In case of a warranty claim, the execution of these essential replacement/cleaning operations must be demonstrable through an invoice. If they do not appear, the warranty claim will NOT be considered.

 

DEPENDING ON THE IDENTIFIED ISSUE, PERFORM THE FOLLOWING OPERATIONS FOR A CORRECT REPLACEMENT OF THE TURBO.

 

LUBRICATION

- Thorough cleaning and/or replacement of the oil inlet and outlet pipes.

- The turbo failure may have generated metal shavings circulating freely in the lubrication system. Before performing the intervention, replace the lubricating oil along with the respective filter. After the intervention is completed, briefly run the engine to facilitate the removal of impurities and change the oil and filter again.

- Check that the oil pump pickup inside the sump is not clogged. If so, clean thoroughly and/or replace the oil pump.

- Check the efficiency and perform a thorough cleaning of the oil vapor recovery valve.

ASPIRATION ( The turbo whistles during acceleration )

- Check that the air intake hoses of the turbine do not have cracks; if they do, replace them. A small piece of rubber sucked in by the turbo that impacts against the impeller at a speed of 100.000 rpm has devastating effects.

- Change the air filter.

- Clean and/or replace the intercooler and the related hoses.

EXHAUST ( The turbo whistles on release)

- Check the integrity of the internal module of the FAP/DPF/CAT and replace it if necessary. If it is intact perform an internal regeneration/washing.

- Check the efficiency of the EGR valve. Carry out a thorough cleaning of it and the exhaust gas recirculation system ducts.

Techinical Info

The BMW OE turbocharger 11659895980 is a component manufactured by Continental and is specifically designed for B38 1.5-liter three-cylinder gasoline engines, in production since 2015.

 

Vehicle applications

BMW

  • Series 1
  • Series 2
  • Series 3
  • Series 4

DIPA can intervene to overhaul this important component for the proper functioning of the engine as well.

 

Typical faults

Coolant leaks

The turbocharger cooling system is sealed with a rubber O-ring. With aging or exposure to repeated thermal cycles:

  • Coolant leaks can occur
  • Overheating can damage the turbo or the engine
  • In many cases, the leak is visible as a whitish residue near the fittings

Wastegate and actuator failures

The wastegate is responsible for regulating boost pressure:

  • Mechanical failures (wear of moving parts) can occur
  • Electronic failures (actuator malfunction) can occur
  • Symptoms include metallic noises during acceleration, power loss, or dashboard error messages
  • In some cases, replacing the actuator or the entire wastegate assembly is necessary

Power loss and abnormal oil consumption

These two symptoms can indicate internal wear of the turbocharger:

  • Often observed between 60,000 and 100,000 km
  • Oil consumption may be caused by leaks through the turbine
  • Power loss is due to reduced compression efficiency

Prevention and proper maintenance

The lifespan of the OE 11659895980 turbocharger largely depends on how the vehicle is maintained. By following some good practices, it is possible to significantly reduce the risk of premature failures.

 

DIPA recommends:

  • Regular oil changes with high-quality lubricants
  • Strict adherence to BMW-recommended specifications
  • Use of efficient oil filters to prevent circuit contamination

Periodic checks

  • Verify the integrity of the cooling lines

Considerations for replacement

When replacing the OE 11659895980 turbocharger, it is essential to follow a correct procedure both before and after installation. Some recommendations:

  • Thorough cleaning of oil and air pipes
  • Replacing any gaskets and O-rings
  • Priming the oil before startup
  • Checking and, if necessary, resetting parameters in the control unit

Neglecting even a single step can compromise the effectiveness and lifespan of the new turbocharger.

 

Conclusion

The BMW OE 11659895980 turbocharger is a high-performance component, essential for the efficiency of B38 engines. However, like any part subjected to intense thermal and mechanical loads, it requires careful maintenance, regular diagnostic checks, and attention to early signs of malfunction.

DIPA offers a wide range of spare parts: from original to aftermarket components selected among the best manufacturers on the market. Not only that: it offers overhauled components with performance equal to new ones, providing savings on replacements and contributing to environmental protection through circular economy. If the spare part you need is not available, don’t worry: DIPA can overhaul your part “on demand,” restoring full functionality and safety in a short time.
