Important Notes on Your New Diverter Valve

• Turbosmart accepts no responsibility whatsoever for incorrect installation of this product which is potentially hazardous and can cause serious engine damage or personal injury
• The EM series diverter valve is designed for use as a factory replacement for a turbocharged vehicle that utilises an electronic diverter valve, this valve can be used on other applications so long as there is a control signal to actuate the diverter valve.
• Ensure the engine is cold prior to installation.
• For Standalone ECU configuration, ensure valve is not energised for indefinite periods of time as this can cause significant life detriment to the actuation solenoid. 
• Recommendations
• Turbosmart recommends that your Diverter valve is fitted by an appropriately qualified technician

About Your EM Series Diverter Valve

Turbosmart has developed a unique “plug and play” diverter valve (or bypass valve) upgrade for your vehicle that is currently equipped with an electronic diverter valve. While we have developed this unit to be as simple as possible for you to install, we have not compromised on performance. This unit will not leak under elevated boost pressures and will still provide you with rapid response ensuring that all the OEM calibration strategies are not interfered with, providing you with maximum boost performance while the advanced strategies of the OEM’s are retained.

As the valve is completely controlled by the factory engine control unit, the factory diverter valve is almost silent, due to our construction, it is possible that your EM series will be much more audible. By being able to hear the unit actuate, occasionally the valve may be opening for a few seconds under the following events such as traction control, cruise control management, rapid gearchanges and varying throttle position changes, these are all coded as part of the torque management software in the OEM engine control unit, there is no adjustment available over these functions via our product. By hearing these events, it is not abnormal, it is completely normal for the EM series diverter valve to be considered “very active” as it is protecting your turbocharger from surge events or bypassing air for torque management purposes.

Fitting your EM Series Diverter Valve

Identify diverter valve location

The factory diverter valve is mounted on the compressor cover of the turbocharger, it is on the passenger side (LHD), removing the engine cover is simply done by pulling up and setting aside.

Note: The pictures are of a USA delivered car. The passenger side is the right hand side as referenced from drivers seat. 

CAUTION! The turbocharger assembly may require the vehicle to be raised on a hoist or jacked up and secured using vehicle jack stands, ensure your safety is not compromised. Identify OEM diverter valve location  

NOTE! Allow for the engine to cool down.

Removing Passenger Side Strut Brace

Once the engine guard is removed, you will be able to remove the passenger side strut brace. E16 and 16mm are used to remove the support.

Removing Mass Air Flow Sensor and Intake Worm Clamp

Sliding grey locking tab and pushing down on tab and pulling back will remove the mass airflow sensor wiring. Worm clamp can be loosened off to allow for air intake to be removed. 

Removing Intake

Remove airbox by carefully pulling up on the outside edges and removing from the inlet tube off the airbox. 

Locating OEM Diverter Valve

Once diverter valve has been located. It is held in by 3 T30 Torx bits. 

As before we need to push grey clip back and then pinch plug together and pull apart. 

Installing Turbosmart Kompact EM

Using the 3 supplied Allen screws to install your new Kompact EM. Please make sure to note the orientation of the flange (opening to passenger frame rail). Making sure to connect the wiring that was previously attached to the OEM diverter Valve. As before, the grey tab should be pulled back until plugs are together and then locked in place. 

Reinstall Air Box

Pushing the airbox back into its locator holes ensuring to feel the feedback of the airbox locating in place. Both the worm clamp and wiring connector should be put back in place as before

Reinstall Passenger Side Strut Brace and Engine Cover

Using E16 and 16mm to fit the strut brace as well as putting on the engine cover making sure to push down a waiting for the feedback of the engine cover to latch in place. 

Congratulations, your EM Series diverter valve is installed dn ready for use, double check all electrical connectors and mounting screws. 

Troubleshooting

Diverter valve not actuating - Confirm electrical signal plug is connected appropriately, as the plugs are new, some force may be required to click the plug into place.

Valve is staying open - Confirm the valve has O-rings as they may have been dropped or lost during installation.

Boost Pressure loss or lower than before - Confirm the valve has O-Rings as they may have been dropped or lost during installation.

Failing the above, submit a technical request to [email protected] with information of your engine configuration and photos of installation.
