Volkswagen Passat BorgWarner New Turbo Actuator 1.4 & 1.9 Tdi (KKK Turbo)
It’s well known that electronic turbo actuators help to hugely improve the efficiency of the turbocharger. Compared to their pneumatic counterparts, the actuation time is reduced by up to 30%, and that’s one of their main advantages. But, as any electronic component in your Volkswagen, the electronic turbo actuator is also prone to faults.
At Autotronics we can offer a replacement for your Volkswagen Passat turbo actuator
The most common symptom that could point to a turbo actuator failure is the loss of power, either permanent or intermittent. If you are experiencing a permanent loss of power, the most probable cause would be a fault in any of the actuator’s internal components. By contrast, if the fault is intermittent the most plausible cause for that would be turbocharger issue, which would make the vehicle to be put into limp mode to avoid any further damage to the engine, although this would have to be confirmed.
If you are having problems with your Volkswagen Passat wastegate actuator and the part numbers and/or vehicle model match the ones on this listing, order a new one from Autotronics.
The quickest way to check if the issue you are having is related to a faulty turbo actuator is by plugging a diagnostics machine into the vehicle to get the actual fault codes. If the fault codes point to a turbo actuator failure, contact Autotronics for help.
Another simple test you can do to check if the turbo actuator is working fine is to verify that the actuator’s arm is moving fine to close the VNT (variable-geometry turbocharger) while revving up the engine. If the arm is not moving, then there is a problem either in the VNT mechanism or in the electronic turbo actuator. You can rule out a VNT or nozzle ring failure if you can easily move the actuator’s arm over the whole operating range by hand, without sticking.
So, for a quality replacement service of your turbo actuator, trust Autotronics.
