Turbochargers with carbon build-up inside the turbo stick onto the variable vanes which causes the vanes to stick. When using either of these two turbocharger cleaners you DO NOT have to remove or dismantle the turbochargers, as they will clean the VNT turbo vanes whilst the turbo is still on the car, and as an added bonus these turbo cleaners will also clean the EGR valve on the engine.
When your car or van has gone in to limp mode and you have an engine warning light on the dash or an injector warning light to the dash board, you might also have turbo actuator problems. normally a sticking turbocharger actuator causes over boost or under boost problems on your vehicles with VNT turbos, Here at turbovanes, we offer both vacuum turbocharger actuators for a cheap turbo repair as well as electronic turbocharger actuators.
Most commonly sold here are the Ford Mondeo 2.0 tdci electronic turbo actuator, jaguar electronic actuator repair and BMW turbo actuator repair,Mercedes electronic turbo actuator repair,other electric turbocharger actuators are also available.
Electronic turbocharger actuator can be identified as a ‘black box’ which would be mounted onto the aluminium housing of the turbocharger which would be connected by a turbo rod to the VNT outside the turbo.
The new vacuum turbo actuators come with a 12 month guarantee and the reconditioned electronic turbo actuators also come with a 12 months guarantee both with unlimited mileage guarantee.
Why buy a new diesel turbochargers when you can repair your own diesel VNT Turbo for a fraction of the cost by replacing the turbo nozzle ring,turbo vanes or the turbo actuator on your own turbo for a fast and cheap turbo repair.
VNT Turbo Vanes have replaced the original and older type of turbo wastegate actuator system on most diesel turbochargers. The reason being is to improve fuel economy, to reduce emissions and to make the turbos more responsive even at low speeds.
Turbo Vanes are a row of vanes fitted inside the turbo chargers which will match the boost required from the engine through the engine revs. The Turbo Vanes or turbo nozzle ring will close there by giving a rapid boost and response time, and also lower the turbo LAG prone to the wastegate turbo actuator. When the engine is running at higher RPM the VNT turbo vanes close to maximize exhaust flow, and avoid over speeding or over boosting and damaging the turbochargers or even damaging the engine.

We also offer free technical support before and after sales. Just email , phone or text to request a call back to you or your mechanic.
TURBO PROBLEMS WHAT CAUSES A TURBO WHISTLE OR TURBO WHISTLING NOISE ?
Turbo whistle is normally caused by either an air leak on the engine , so check all the air system from air box to turbo, and turbo to intercooler, intercooler to inlet manifold, both inlet and exhaust manifold gaskets and finally turbo to exhaust pipe, this can easily done by using a gas leak or smoke test machine, which most vehicle diagnostic garages can do for you at low cost.
The other thing which can cause a turbo to whistle is the turbo nozzle ring or turbo vanes get stuck with carbon, causing the turbo vanes to be stuck in full boost and overspeed the turbochargers beyond its standard speed/ balancing range causing a turbo whistle. These turbo problems are caused by either injectors not working properly, oil in the intercooler or an engine breather problem.

Variable Vane Turbo Problems – common Turbo faults Find us on Google+ Turbocharger Diagnosis and Repair What does it mean when your car goes into Limp Mode?In this day in age, most systems in your vehicle are electronically controlled by computers. Limp Mode or sometimes called Fail Conditions comes into play when the vehicle computer has detected a problem with one of the major systems within its logic computer.A reading from any sensor, and the ECU computer knows that the readings are outside of the correct ranges. The module can’t process the correct outputs based on the data it has. When this happens the vehicle’s ECU computer will create a trouble code and turn on a check engine or other malfunction indicator light.
SYMPTOMS OF LIMP MODE
- None or slow acceleration
- The intake could be blocked with carbon
- Speed is restricted
- Sticking turbo vanes or actuator
- Exhaust leak could cause the car to enter Limp Mode
MOVING THE CAR TO A SAFE PLACE
The whole idea of Limp Mode was designed to allow the driver of the vehicle to move the car to a safe place, off a busy road or onto the hard shoulder on a motorway. In some cases the car is still available to drive, although maybe not to the full potential. Allowing you to drive the vehicle home or back to a local garage for a diagnosis.
NEXT STEP
If your car has entered Limp Mode, when you have arrived at a safe place you may be able to shut down the vehicle, waiting a few minutes before starting the vehicle up again. In some cases, this resets the electronic controls, restoring the data. Although the car may run like normal it is still advised to get your vehicle checked out by a local mechanic for a check as the original fault may not of disappeared. If the vehicle does not reset, you will need to take the vehicle to a local mechanic for a complete test and diagnosis.
OVERBOOST
Over Boost can be caused for many reasons, the most common ones are listed (below)
| Possible Cause(s) | Solution |
|---|---|
| Air Leak | Fine the leak, and replace/repair pipe/gaskets |
| Turbo internals may be damaged | Diagnose and Repair / Replace Turbo |
| Foreign Matter (Impact) may of entered the inlet pipe | Replace the Turbocharger |
| VNT Blocked | Replace and Repair Turbo |
| Actuator settings may be wrong | Replace Actuator |
| Possible Cause(s) | Solution |
|---|---|
| Internal Engine Components Worn | Repair the Engine / Replace worn parts |
| Air Filter Blocked | Replace the Air Filter |
| Turbo internals may be damaged | Diagnose and Repair / Replace Turbocharger |
| Air pipe (to the turbo) is restricted | Replace the Air Pipe |
| VNT Blocked | Replace / Repair Turbo |
| Airleak | Find the leak and replace/ repair pipe/gaskets |
| Actuator Arm is Stuck Open | Replace Actuator |
LOW BOOST
When the engine lacks power or has low boost there can be a variety of possible causes for this. Check the possible causes (below) and then match it to the solution.
STICKING VANES
VNT Turbo Vanes have replaced the original and older type of wastegate system on most diesel turbochargers. The reason being to improve fuel economy, to reduce emissions and to make the turbocharger more responsive even at low speeds.
Turbo Vanes are a row of vanes fitted inside the the turbocharger which will match the boost required from the engine at low engine RPM. The VNT Turbo Vanes will close thereby giving a rapid boost and response time.
They also lower the LAG prone to the wastegate type turbochargers. When the engine is running at higher revs the VNT turbo vanes open to maximize exhaust flow, to avoid over-speeding or over-boosting and damaging the turbochargers or even the engine.

TURBO PROBLEMS AND FAQS
TURBO PROBLEMS AND FAQS What does it mean when your car goes into Limp Mode? You can think of “Limp Mode” as an “emergency mode” used by your vehicle Electronic Control Unit (ECU) to protect the engine and transmission from serious damage. The “Limp Mode” feature programmed in the ECU can reduce engine power, turn off A/C, and sometimes manipulates the automatic transmission to allow you to drive the car safely. If the Check Engine Light is lit or the information center is showing up a warning message, then we strongly suggest to pull over or drive to the closest repair shop. Driving for prolonged periods of time in Limp mode may cause major mechanical breakdowns to the engine and/or transmission. It’s safe to drive my car in Limp mode? Absolutely. The Limp mode allows you to drive your vehicle (with reduced power) so you can reach your destination. Once you get home or any other safe place, it’s strongly suggested to book a visit with a local repair shop to diagnose the root of the problem.

(Common Causes and Solutions) Turbo overboost most common causes are air leaks, damage on turbo internal parts, debris impacting the turbo, a blocked VNT mechanism, or wrong turbo actuator settings. With the exception of air leaks that can be easily fixed changing the appropriate gaskets, most of these issues will require repairing and/or replacing your turbocharger or turbocharger internal parts. What causes a turbo low boost? (Common Causes and Solutions) An underperforming turbo boost is commonly caused by air leaks, a clogged air filter, damage on turbo internal parts, worn engine components, a blocked VNT mechanism, or a restricted turbo air pipe connection. Air leaks, air filter, and air pipe issues can be easily fixed by a competent mechanic, however, the rest of these issues will require repairing and/or replacing your turbocharger or turbocharger internal parts. What are the VNT turbo vanes? VNT turbo vanes consist of a mechanism inside the turbocharger that helps to decrease engine lag at low RPM as well as preventing turbo overboost at high RPM. To achieve this goal, turbo vanes are operated by a turbo actuator (either vacuum-operated or electronically controlled by the ECU) to increase or reduce exhaust flow. facebook google twitter contact faqs news
