Vauxhall Vivaro losing power

I am having some problems with my 2005 Vauxhall Vivaro van. The engine has virtually no power until it reaches 25000rpm. I’ve changed the air filter, mass air flow meter/sensor boost pressure sensor, and turbo sensor, but still no joy. Any ideas?

This fault could be a number of things. It may be best to have a diagnostic check carried out ,which should then show up a fault code (ie P ---- 4 numbers).
This code can then be related to the problem - may well be one of the many sensors fitted. Doing a diagnostic could well save both time and money in the long run.
