Leon st 1.2 bad turbo acuator?

[David_Sgv]

Hi everyone
Im driving Leon st mk3 1.2 2016.
Epc+check engine light turned on yesterday and the car got in limp mode and accelerate baddly

I have scanned the fault code and got this codes:
P00AF
P003a
16434

I suspect its the turbo actuator seized or not moving freely as it should.

someone familiar with those codes and help out?

16434 is a lambda fault for an implausible or intermittent signal. Check the wiring of the sensor on the catalytic converter behind the turbo. Also, check any vacuum lines for leaks.

Under the 16434 is the the p334p that indicates something is faulty in the turbo accuator

The turbo actuator is worth greasing anyway. My son's stuck and I greased it up. Been fine for two years now.

Do you mean to grease the actuator rode?

Do you mean to grease the actuator rode?

Yes. There is a linkage at the solenoid end that can stick.
