Yes and kinda. The engine powers the turbo as it runs. So when you drive the car, it powers the turbo. If the turbo isn't working properly, you'll possibly damagethe car even more. They aren't terribly difficult to change but are a bit expensive. See if you can find a used parts locator service online and just go with a guaranteed used replacement.

Yes, replacement can be pricey. The engine is de tuned to allow for the pressure of the turbo, so without one you will not have much performance.

I need belt diagram for a Mazda Millinea s 2.3 with turbo. I need the belt that works the turbo


There is no belt that runs the Turbocharger. A Turbocharger uses the engines exhaust to spin a wheel that is attached to a compressor wheel.

Elantra 2004(Diesel, done 136,000km) Leak in Turbo Charger


A turbocharger can leak. Some of the gaskets might be shot and need to be replaced or a hose might need to be replaced. If the turbocharger itself is leaking and not a gasket then the turbo housing is probably cracked. If you get the turbocharger replaced it should last a good 20 years or so. The only thing that usually wears out on turbochargers are gaskets and thrust bearings.

How to recognize if my turbo is causing blue smoke from the exhaust vs a blown head gasket. I don't have anti freeze mixed with my oil but it smoke coming out the exhaust when the car is running. ...


It's very simply to find out if the turbocharger is causing blue smoke from the exhaust vs a blown head gasket. So, remove the turbocharger's compressor inlet centre hose (from the aluminium side of the turbo). Then see if there's in plenty of oil coming out from the hose and from the turbo. I'm 100% convinced that the turbocharger is damaged in your case. You can remove also the exhaust pipe out from the turbocharger, and see if there's a lot of oil coming out.
Repair or replace bad turbocharger with a new one (or with a second hand in good condition one). Good Luck!

In your case the turbocharger is responsible for engine losing power.
The car goes in "limp home" mode!!!
After scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this: Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increases too much and ECU (engine control unit) goes in "limp mode" = engine protection software. As a result the "limp home" mode engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECU memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.

Hello.I got my Volvo s40 2002.Its suppost to have a turbo build-in.But I cannot feel the difference,basically when is turbo starts working?Thanks!


The S 40 came with different size and spec engines and they were not all Turbo charged versions. The choice of engines available depends on which country you are in.

The turbocharger is driven by the engine's exhaust system and runs continuously but has minimal affect at low engine RPM. Unless the turbo has failed, you should feel the turbo effect kick in when you accelerate hard but there will be a brief lag .

If you have the turbo engine fitted to your 2002 model S40 you will have a " 1.9T " badge on the rear of your car under the S40 badge. The "T" designates Turbo. An engine designator badge without a "T" indicates it is not turbocharged.

The turbochargers on these S40 models will fail (especially if the car has done a lot of miles) so you should have your car examined if you feel the turbo is not functioning.

Turbo/supercharger under boost


Turbocharger under boost problem:
The car goes in "limp mode"!!!
After scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this DTC - Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.

Nissan Navara STR 2006 d22 3lt turbo. Turbo is whistling very


Remember, what is heard as turbocharger noise may not be caused by a noisy turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration and increases or decreases with rpm and load. This condition is most often the result of a loose clamp/hose at the turbocharger compressor outlet, charge air cooler inlet, outlet or at the intake manifold.

1. With the engine running at idle and the transmission in Park or Neutral with the parking brake set, feel for boost air escaping at each connection between the turbocharger compressor outlet and intake manifold. For limited access areas, spray soapy water on those connectors and look for bubbles.

2. Check the exhaust manifold and exhaust system for leaks.

I hope this helped.

Thank you,
Norse

Turbo does'nt work


How do you know the turbocharger doesn't work? Just because the boost gage doesn't show boost PSI doesn't mean the turbo isn't working. Junkyard or rebuilt turbos aren't cheap but they're less expensive than a new one from a dealer. Don't buy a old turbocharged Volvo they're money pits. They always break down and parts are really expensive (and hard to find on older models) and you have to find a mechanic that specializes in fixing Volvo's.
