Does anyone know what a healthy TD4 turbo boost pressure would be? Ive done the searches but no luck
hmm sounds like mine is under boosting then as I am only getting 15-16psi im using dash command

Might be measuring in psig, if it is add 14.7 psi to convert to psia
cheers .. just now learnt somethin' new
had never heard of 'psia' and 'psig' .. 'till now ..
a quick Google search clarified that one ..
if your reading goes below 14.7 psia its actually pulling a vacuum
or one is situated fairly higher than sea-level .. engine at idle .. ??
saw mine at 13.9 once ( @ idle ) .. was wondering what was going on 'till i realised were i was ..
( hopefully that was the explanation .. 'n not something worse
no alps here .. just some big hills ..Where were you, half way up an Alp
What's confusing is the haynes manual stating the turbo max boost is 1.75 bar which is 25psi give or take
