Original boost pressure sensor: kPa value.

What is the original boost pressure sensor (intake manifold pressure sensor) pressure in kPa, as measured by the engine control unit (ECU) of a Golf 3 TDI with a 110 hp AFN engine?

"I'm always getting the error codes 'intake manifold pressure control difference' and 'control unit intermittently defective', and I have a sensor installed that reads 250 kPa. However, I've read several times that it should only be 200 kPa."

So, what is correct?

250 kPa
