There are two numbers that will normally identify a turbocharger. The OEM Part Number (Original Equipment Manufacturer Number) or the Turbo Manufacturer Part Number. To clarify O.E.M. is the Vehicle Manufacturer such as Audi, BMW, Ford etc.
If the turbocharger is still fitted to the vehicle then the best approach is to obtain the OEM number from the local main dealer parts department by asking for their price to supply. You will need to give them either your Vehicle Registration Number or Vehicle chassis number. However you may find that the main dealers will give you a price but maybe reluctant to give you the OEM number for use elsewhere and only offer their internal part number. This may still be OK to cross reference.
The alternative to this is to try to retrieve the numbers from the actual turbocharger identification plate. This may mean trying to read them while the turbocharger is still fitted to the vehicle which is not ideal, so you may have to wait until the turbocharger has been removed from the vehicle.
1 O.E.M. Part Number (Vehicle Manufacturer = O.E.M)
The OEM Number is normally issued by the vehicle manufacturers such as: Audi, BMW, Ford, Mercedes, Toyota, VW etc and can also be found actually etched on the identification plate on the turbocharger.
Below are just a few examples of what vehicle manufacturer’s OEM part numbers look like, however bear in mind that vehicle manufacturer’s are not typically exclusive to one turbocharger manufacturer for their range of vehicles. For instance Audi fit both Garrett and BorgWarner KKK turbochargers to their engines while BMW use both Garrett and Mitsubishi turbochargers across their range of vehicles:
|Vehicle Type||OEM Part Number||Turbo Manufacturer|
|Range Rover Sport 2.7L D||4H2Q 6K682 CK||BorgWarner KKK|
|BMW 320d 2.0L D||11657795499 or 7795499||Mitsubishi Turbo|
|Ford Mondeo 1.8 TDCi||7G9Q-6K682-BD||Garrett Turbo|
|Mercedes Vito 2.2L D||A6460960199||IHI Turbo|
|VW Golf 2.0 TDi||03L 253 010C||BorgWarner KKK|
|Toyota Previa 2.0 D4-D||17201-27030||Garrett Turbo|
2 Turbo Manufacturer Part Number
The other part number used to identify your turbocharger is issued by the actual turbo manufacturer. This can be found actually etched on the same identification plate as the OEM number on the turbocharger. The most common turbo manufacturers for passenger vehicles include: Garrett, BorgWarner KKK, Mitsubishi, IHI and Toyota.
Examples of how the part number would look for the turbo manufacturers are as follows:
|Vehicle Type||Turbo Manufacturer Part Number||Turbo Manufacturer|
|Range Rover Sport 2.7L D||53049700069 or K04-69||BorgWarner KKK Turbo|
|BMW 320d 2.0L D||49135-05671||Mitsubishi Turbo|
|Ford Mondeo 1.8 TDCi||763647-21||Garrett Turbo|
|Mercedes Vito 2.2L D||VV14 or VF40A132||IHI Turbo|
|VW Golf 2.0 TDi||BV43B-0139 or 5303-970-0139||BorgWarner KKK Turbo|
|Toyota Previa 2.0 D4-D||721164-9||Garrett Turbo|
Here are some examples of where the part numbers can be found physically on the turbocharger. The numbers are frequently hard to distinguish so may need the area cleaning. It is very important not to use a heavy abrasive as this may result in the number becoming illegible or worst remove the numbers completely. It’s better to use something like brake cleaner and scotch bright.
