v6 power loss

Post by jasonbrooks1575 »

ive got a vw passat 2.5 tdi v6 auto estate it goes ok through 1st & 2nd gear doing 4,000 revs then wont change up to 3,4,5 automatically i can change manually 3,4 goes to 5 but changes back down wont do more than 2200revs.if you manually pump some fuel to filter system it goes back to normal for about 40 secs to a minute going right round with the revs & changing up the gears.
its had a full service problem still there.
ive got a friend to do a diagnostic with his bosses machine(he smuggled out of work)its come up with a 00575 intake manifold pressure(below pressure). where should i look & replace what ( my mates only a valater)
