2.0 TDI PD Injectors: VW Audi Performance

Hello everyone,
I need your help!
Maybe you can help me!!!

What are the differences between the PD elements in the new Audi A3 and the Golf 5 2.0 TDI?
'Is this for a Golf 4 with a 1.9 TDI engine and 150 horsepower? I heard that they use the same parts there.'
will be, and the new 2.0 TDI only operates with slightly less boost pressure!!!

I would really appreciate any information you can provide.
Best regards,
Alexander.

Hi,

"So, does the 4V engine have the same "large" direct-injection (DI) elements as the 2V engine? I find that hard to believe."
As far as I know, the PD injectors for the 2.0 16V engine are significantly smaller. At this point, I'm not surprised by anything Volkswagen does anymore.

no, they are NOT the same.

The 2V models have UI-1.
The 4V models have UI-2.

reason: centrally located injector, which means it has to be designed to be significantly thinner.

"Yes, exactly. What about the turbo boost pressure of the 2.0-liter engine? Logically, it should be lower than the ARL, and possibly even lower than the ASZ and other models? Or am I mistaken?"

However, the pressure of the individual PD elements is still the same, or has VW implemented a slimmer design with higher pressure?

Thank you for your quick response!

This forum is simply amazing!

The turbocharger pressure will be lower due to the four valves, but this results in >> better cylinder filling!

@matthias: The pressure should be almost the same from the PD elements.
But they plan to increase the pressure to a staggering 2700 in the near future.
