Your bearings are dieing, the turbo is done and you should replace it because a smoking turbo can ruin your engine because some parts of the turbo can be blow'd into the cylinders and your engine is toasted.
How do you blow a engine turbo.
Electronic engines do not have exhaust gasses. Therefore a turbo has no way to operate because a turbo functions off the exhaust gasses of a engine.
It does not because the body is light so the engine does not support a turbo system
A twin turbo engine is an engine wielding two turbochargers.
No, the turbo is powered by the exhaust and uses no engine power.
not because its a turbo but a diesel will at very very cold temps. for an extended time
=because there are cool=
Turbo position is on the right front next to the p/steering pump if your A4 is a turbo unit if not it mite be a A4 L only no turbo specification. You can not install turbo because the piston are different from the turbo engine.
a non-turbo engine will not hold up to the turbos you will have to put in hardened internals
The 1.8 turbo is more powerfull. The turbo charger pushes more air and fuel into the engine.
