hello all im new here and would appreciate any help you can offer me.i have fault code p0 23d-22, manifold absolute pressure turbochare boost sensor a correlation.an engine system fault notice also appears.my mechanics computer is not telling him any more so was wondering what the most likely causes are.its an 08 tdv6 71000miles,egr valves done recently.many thanks

More than likely a split hose at the front of the engine, between the engine and intercooler. Failing that, a seized actuator rod

Thanks il get that checked sounds relatively painless for once!cheers

It was actually one of the pipes or hoses not sure that went it to the new erg valve,it had come loose.all fixed now.hope this helps someone else.
