A faulty turbo is indicated by pure black smoke when engine revs are above idling revs and it can also be shown by poor machine performance.
not really. You can get blowby in the turbo itself from high crankcase pressure, but a turbo won't cause engine blowby.
The whistling will be from a faulty turbo charger
It can be a few things, turbo seals leaking faulty crankcase valve faulty bell pan.
Faulty waste gate, improperly sized turbine housing.
You measure the wheel size of the turbo. fr example you will get 50mm and this will tell you how big the actual turbo is. you cant really tell by the trim
Make sure the boost air isn't escaping from anywhere; for example the piping which runs from the turbo, to the intercooler, then to the engine. If any of this is split or frayed then your engine will be getting a lot less boost than it is supposed to. As well as this it could indicate a faulty turbo. Or a faulty wastegate, in which case you will need to replace the turbo unless you have an external wastegate, in which case just replace wategate
VG30DETT is Twin Turbo VG30DE Non turbo
Yes it will smoke a little bit from it but if it is smoking a lot then its burning something.
No it dosent but fix it ir replace because the air and fuel ration is the key to cumbustion and a faulty turbo is less air/oxygen to the fuel which means your engine wont properly burn the fuel which means you can mess up your engine bad
tsi is for turbo I belive. Mine is a non turbo esi.
No, only the faulty one, the fault code will tell you which is faulty.
