Turbocharger Boost Pressure Explained

Can someone tell me what boost pressure my T-loader should be producing?

'Recently, I've been experiencing a lot of smoke when accelerating, especially above approximately 2500 RPM.'

That's a really good question, and I'm also noticing that the database of actual values seems to be incomplete.

I would generally say that anything below 0.9 bar is not good.

Otherwise, check the other possible causes of the error as described in the technical article.

Or simply use VAGCOM to log the boost pressure control (including the current target value).

Then, practically, you don't need a table .

But, strong smoke when accelerating usually has different causes than low boost pressure -> check the EGR valve to ensure it's completely closing, and check for "vacuum" leaks in the intake manifold between the turbocharger and the engine.

Sorry, but that's where the wisdom ends.
How can I check that?

Hi,

That would be my first suspicion. A visual inspection might also help in this case.
