This plug provides a quick solution to the common 'Swirl valve fault'

that occurs on the OM642 V6 Diesel engines fitted to various Mercedes, Chrysler and JEEP Car Van and 4x4 models.

This plug connects in place of the faulty Pierburg 6421500494 swirl valve actuator motor and fools the car into thinking that the motor is working.

This plug has included the resistor
 

The plug will work with the following Vehicles:

Chrysler

Chrysler 300C (2006-2011) (Europe, Australia and New Zealand only)

JEEP

• Jeep Grand Cherokee WK/WH (2005-2010 (Europe)1, 2007-2008 (North America)2)
• Jeep Commander XK/XH (2006-2010 (Europe))

Mercedes:

• Mercedes-Benz Sprinter 3.0L (2006–)
• Mercedes-Benz Freightliner 3.0L (2006-)
• Mercedes-Benz Vito 120CDI & 204CDI Sports (2006-) Europe & Australia
• Mercedes-Benz C320 CDI (2005–2007)
• Mercedes-Benz E280/E300/E320 CDI/BlueTEC (2007-2009)
• Mercedes-Benz C350/C320 CDI (2009–2014)
• Mercedes-Benz CLK320 CDI (2005-2010)
• Mercedes-Benz E350 CDI/BlueTEC(2010–2016)
• Mercedes-Benz E 350d (2016–2018)
• Mercedes-Benz G320 CDI/G350 CDI/BlueTEC (2007–2018)
• Mercedes-Benz GLK 350 CDI (2013–2015)
• Mercedes-Benz R320/R350 CDI/BlueTEC (2007–2012)
• Mercedes-Benz ML280/ML300/ML320/ML350 CDI/BlueTEC(2007–2011)
• Mercedes-Benz ML350 BlueTEC/GLE350r (2011–2018)
• Mercedes-Benz GL350/320 CDI/BlueTEC (2006–2012)
• Mercedes-Benz GL350 BlueTEC/GLS 350d (2012–2018)
• Mercedes-Benz GLC350d CDI (2016-2019)
• Mercedes-Benz S320/350 CDI/BlueTEC(2005–2013)
• Mercedes-Benz S350 BlueTEC/S 350d (2013–2017)
• Mercedes-Benz CLS 320/350 CDI (2005–2011)
• 2009 and later OM642 Engines - This plug will work BUT the ECM will need tuning because these engines have sensors fitted to verify that the swirl valve is opening and closing.

There is much information relating to this on car forums and on a certain video sharing website


The Swirl valve can be effectively bypassed by fitting a resistor across 2 of the connections on a plug that connects to the Pierburg 6421500494 actuator motor.

All parts and materials used are high quality and are designed to withstand the very high temperatures in the engine compartment.

Once fitted, the engine fault code MAY need to be cleared using a fault code reader - you will need to either buy your own or get someone to do this for you.

You will receive the bypass plug with resistor. I do not offer instructions as the fitting will be specific to your car model, as will be the clearing of the fault code(s)
