Audi A4 (B7) Hella Turbo Actuator Repair (Garrett 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 Audi, the electronic turbo actuator is also prone to faults.
At Autotronics we can repair your Audi A4 turbo actuator, with a guaranteed service. Thanks to our advanced testing and repairing equipment, and our vast knowledge of the vehicle electronics business, you can be confident that we are the best alternative for repairing your faulty 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 Audi A4 wastegate actuator, send it to Autotronics. Our highly-skilled engineers will test it, identify the source of the problem, fix it and test it again before sending it back to you.
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.
Apart from a quality and guaranteed service, having your item repaired by us will help you save up to 80% compared to the main dealership’s alternative. Their alternative will 99% of the cases consist in replacing the whole set of turbocharger and turbo actuator, at an exorbitant price.
So, for a quality repair service of your turbo actuator, trust Autotronics.
