My 1.9tdi seems to have lost boost. The change over solenoid came of its bracket and has melted to the EGR inlet. I’ve removed the change over solenoid and plugged the vac lines but still got no boost and struggles to start. Hasn’t thrown a EML? Any thoughts why it’s still not boosting? I don’t have a code reader so any help would be appreciated

check if you've done the new vacuum pipes the right way around... if you haven't than that'll be your problem, that is if the replacement valve works... there is a vacuum simplification topic in the how2's that'll show you how it should be connected ( the vacuum pipes)
