What are the symptoms of a turbo going bad?

  1. Loss of power or boost.
  2. Slower, louder acceleration.
  3. Difficulty maintaining high speeds.
  4. Blue/grey smoke coming from the exhaust or Irregular excessive exhaust
  5. Engine dashboard light is showing.
  6. Warning signs of turbo failure.
  7. Loud shrieking noise


How do I know if my turbo actuator is bad?

If your turbo has the following symptoms and warnings signs, you need to check whether there is a problem.

  1. Check Engine Light when it is on.
  2. Vehicle’s turbo does not produce boost during acceleration.
  3. Oscillating turbo boost pressure.
  4. Dramatic decrease in fuel economy.

What causes a turbo actuator to fail?

If the variable geometry mechanism is stuck, the turbo actuator will pull a higher current through the motor, especially compared with its designed current to take.

Meanwhile, It will bring about a burn out motor or a broken plastic worm gears. If so, it will reduce the boost pressure and result in home mode.

How do you calibrate a turbo actuator?

Sacer turbo actuator needs Sacer tools to calibrate. If you need to know how to calibrate turbo actuator, please kindly contact us.

How much does it cost to replace a turbo?

Normally, The average cost for a turbocharger assembly replacement is around 5000usd.

Labor costs are estimated from 1300usd to 1500usd, so the parts price is around 3000usd.

  • What is known to us is that a defective turbo actuator brings about more damage to the engine. And it also causes an error codes and less power. Different error codes will show different problems for turbo or a pressure control, the solution is also different. Different brands have their own specific error codes.

The following error codes are just some examples,

  • P0234 – Engine Overboost Condition
  • P0299 – Turbo/Supercharger Underboost
  • P2263 – Turbo/Supercharger Boost System Performance

But, If a turbo is in a good working status, what parts will be broken in the actuator itself? Maybe it is the control unit or the actuator basically consists of an electric motor, a plastic worm gear, a printed circuit board. Sometimes, our turbocharger is just a component broken, but, the car manufactures need our customers to afford a completely new turbo. This is a very expensive for customers. That’s also why the remanufacturing one is the best choice for our customers. Because consumers just need to pay less money to obtain a new turbo for their car. Which part is broken, where we repairing. That’s correct way to help our customers save money and time.

How to check a turbo actuator is in good quality?

Honestly, it is very easy to estimate a turbo charger actuator in good quality or a bad quality,

it is very easy to estimate the quality of a turbo charger actuator.

First of all, you can tell by the qualification and certificates that your supplier already achieved, such as ISO9001 and IATF16949.

Because the manufacturer can’t be approved until they meet the criteria of the certificates.

Secondly, you need to check whether the supplier has its own patents permission, R&D team,

Factory, professional sales team and after customer service, especially whether the company

provide technology supports. Thirdly, you can check the products material and some components,

even the production process and so on.

Regarding the turbocharger actuator, you have to master that whether it is an integrated or pigtail, because which could enables mounting and packing flexibly. Meanwhile, integrated electronics with position sensing provides enhanced accuracy resolution. This is the first thing you have to pay attention to. The second side is that you need to check whether it is brushless motor meatal gears and aluminum body, because it will provide a high torque and extend durability. The third side is that whether it supports a default position and multiple mounting options, which enable various custom mounting options. The fourth thing is that to check whether it belongs an industry standard connector, supporting multiple options from variant cable, making customers easily plug. The fifth thing is to assured that whether the communication is industry standard J1939 CAN Communication. The last thing is to check whether the turbocharger actuator has been strictly and completely tested by manufacture. Such as the HALT testing, vibration testing, corrosion testing, RT durability testing, high and low temperature ageing testing, water proof testing, drop testing, EMC,ROHS&REACH testing, Individual parts DV testing, vehicle durability.


The most important thing is that Garrett doesn’t provide separate parts for VNT turbochargers. So most of the turbocharger related parts are remanufactured. This is why customers have to choose a good supplier.


Sacer has approved the ISO9001 and IATF 16949.

Our products are all designed by European R&D team which can meet the European product quality standards.

What is the function of a turbocharger?

Firstly, A turbocharger, or turbo (colloquialism), from the Greek “τύρβη” (“turbulence”), is a turbine driven forced induction device used to allow more power to be produced by an engine of a given size.Secondly, A turbocharged engine can be more powerful and efficient than a naturally aspirated engine. Because the turbine foreces air and proportionately fuel into the combustion chamber which more than atmospheric pressure alone. If so, we could have a downsize turbocharger on car engine.At the same time, we could satisfy stringent emission regulations.Thirdly, Generally speaking, turbocharger includes a turbine housing/compressor housing and bearing housing. The core assembly is the turbine wheel and compressor wheel. Turbine wheel is used for absorbing exhaust gas energy. Compressor wheel is used for compress flash air into cylinder. After that, The Air booster will provide a power output for the car engine.


What is the function of a turbo actuator?

Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger. As is known to us, a turbocharger also is classified into waste gate turbocharger and Variable Geometry turbocharger, which all needs a control. Normally, Most of cars are used a pneumatic actuator to control pneumatic, but, a pneumatic actuator doesn’t have a good accuracy for control strategy. So, Sacer takes advantage of the electronic actuator to control the turbo. Such as SA1150, SA1140 series


What is the difference between pneumatic actuator and electronic actuator?

The typically distinctive of electronic actuator and pneumatic actuator is the control accuracy. Electronic actuator has a better control accuracy.


Which cars do the electric actuators used? A vehicle installed a Diesel engine? Or a vehicle installed a gasoline vehicle?

Both of them are okay. We have the electronic actuator for diesel and gasoline engine. For example, the product of SA1143 series, which are used for lower than 2.5 liter of diesel engine with a small displacement. Mainly applied on popular diesel passage car(PC) . Such as, BMW, VW, GM, FORD, PEUGEOT. Except for PC of Diesel system, we also have Electronic actuator applied on HDV, the heavy duty car. Such as SA1150 series, which are applied on HDV for Volvo, Daf, Scania. For Gasoline engine, we have T1-T5, which is okay for VW, HONDA, GM, ETC. Widely applied for 1.0 -2.0 liter gasoline engine.
