Does the smoke smell like burnt antifreeze or motor oil?

Yes installing a new turbo is a difficult task. This will include pulling the turbo and piping, disconnection of the oil lines and air lines. And then installing a new one.

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.

tHIS WILL TURN ON AND KEEP THE CHECK ENGINE LIGHT ON, MOST OF THE ENGINE BLOCKS ARE THE SAME BUT ARE BUILT A LITTLE STRONGER TO WITHSTAND THE TURBO, IF HE CONNECTS THE TURBO AND YOU DONT BEAT ON THE MOTOR I THINH YOU WILL BE OKAY, HAVE HIM USE ALL THE OLD PARTS LIKE INTAKE INJECTORS OIL PAN EXHAUST MANIFOLD AND I THINK IT WILL BE FINE, HOPE THIS IS HELPFUL,

Very common problem on Volvo , ABS module is bad.
This is not effecting the brake system , meaning you'll still have normal brake operation , but on slippery road Anti Lock System won't work.
That system prevent wheels to be locked up by driver and prevent car going into spin.

EGR may be sticking open causing lean fuel issue .

Castrol GTX 10w-30 or 5w-30 should work fine. Use 10w-30 if your in a state that gets temperatures below 35 in the winter.

check to make sure the turbo oil return pipe is not clogged. if it is pressure will build up causing oil leak through seal causing it to smoke.
