Leaking Turbocharger Wastegate

The wastegate is a valve on the turbocharger that allows excess exhaust gas to bypass the turbine impeller at high engine speeds. This prevents boost pressures from becoming too high. If cracks develop around the wastegate valve, the exhaust pressure is able to escape through the wastegate even when it is closed. This reduces the amount of exhaust gas available to spin the turbine, and thus lowers the potential boost that the turbocharger can deliver.

What about the oem turbo ones?

[@dylandesmond]

Sometimes 😂.
Thats why you don't buy cheap Chinese knock-offs.

[@nuclearimbecile7674]

Communist knockoffs😂

and if uwant to be more 90s cool get turbo timer on :P

What would cause a once working wastegate to stop opening all of a sudden after induction/boost?

[@foompa]

The actuator loosened from the temperatures expanding the hole for it. It works as a door. Once that hole opens up more then what it is , there’s no resistance. Allowing the waste gate to stay open just the slightest. Causing a major boost leak

@@foompa Would a boost leak throw a DTS?

[@foompa]

@@DavidTMSN I’m sorry dts ? U have me stumped lmao. If ur asking if it throws a code , my gti threw a underboost code

1 Mechanical failure:
The wastegate actuator or linkage could be stuck seized,
wastegate flap/valve itself could be stuck or jammed, not allowing it to move freely.
2 Electrical/control system issue:
A problem with the wastegate control solenoid, wiring, or ECU programming could prevent the wastegate from receiving the proper signal to open.
A boost pressure sensor or other related sensor failure could cause the ECU to not command the wastegate to open correctly.
3 Boost system leaks:
A boost system leak, such as a cracked intercooler or hose, could reduce the boost pressure and the need for the wastegate to open.
This could trick the ECU into thinking the wastegate doesn't need to open.
4 Clogged/restricted exhaust:
If the exhaust system becomes clogged or restricted, it can increase the backpressure and prevent the wastegate from opening properly.
5Wastegate spring failure:
The wastegate spring that helps pull the flap open could be broken or weakened, not providing enough force to open the wastegate.

Same time work and sam time not working.wat problem...

I gave my car to the mechanic. Vw passat b7 2012 to change turbocharger, but after changing the turbo, my car misfires and won't move, and when acceleration, then noise.
Mechanic tries to find a problem, but he can't find he told me he checks everything like leakage sparkplugs, all things that need to be checked for misfire, but he can't find anything. He does diagnostic, and there also shows no problem, but the car won't move, and noise when acceleration

[@Jushwa]

sounds like you need a new mechanic
