SEAT Common Car Fault - Advice Needed

I don't think these two engine are modular Adrian.
The 1.0 and 1.2 are both 3 pots. I'm not sure how much they share but I seem to think the 1.0 replaced the 1.2.

But I'll bet it's the same issue. The three-pot 1.0TSi is the same basic engine as the three-pot 1.2TSi, and it's going to be very closely related to three-quarters of the four-pot 1.2TSi.

Very small engines in reasonably heavy vehicles are great for paper emissions and economy, but they have to be very complex to produce the kind of power required. 115bhp per litre is the kind of figure that used to be reserved for performance cars like BMW Ms and Ferraris only a couple of decades ago.

Thanks Adrian, that's really useful to know.

I doubt the actuator is seized, I believe these have a motor driven actuator rather than a vacuum diaphragm actuator and if arm/pivot that operates the wastegate/vanes within the turbo has seized, it's probably ruined the motor in the actuator as it can't work against so much resistance of the seized arm, but then again it might not.

Thanks for this. That sounds like a plan and much more affordable. I'll call a local specialist tomorrow.
Many thanks for your advice
