04 TD5. Hi all looking for some advice, this is only on start up but my turbo seems to be seized, crawl 10 yard get into 2nd and it kicks in job done happy days no problems. Once it’s going there’s no issues no lack of power no smoke no symptoms of anything else. Any idea what I can do? Worth taking it off and giving it a good clean and look over?

lt's very unlikely the turbo has siezed and is then freeing off.

Check the MAF unit.

lf the MAF has failed you'll get exactly these symptoms.
Also the wastegate could be seized, so check that as well. That can also give the symptoms you are getting.
