Hey guys,
 
I have a 2003 t4 2.5tdi, it runs fine no smoke on start up etc, only done 99k but the turbo doesn't kick in until you hit about 3000 revs.
I didn't really notice until taking it on the motorway and it was gutless, until I wound it up to 3000 and the turbo kicked in and we took off!
any ideas if this could be the infamous N75 valve I keep reading about, or possibly the fuel pump timing? any help much appreciated.

Have you thought about your MAP? It's part of the comparative process to guide the operation of the turbo??

No I haven't to be honest, what is the best way to test it?
