as above ive got a 3.0tdi thats missing over 1400 revs till about 3000 then it continues to rev fine, ticks over spot on?

If you rev it right up from still it appears to rev up the range completely fine?

if you drive it its awful as you accelerate is misses like mad,

its had a new turbo which is working ok and the day after i was out driving when i heard a wierd crackly sound then it stalled completely, i coasted it into a layby checked some stuff (thought turbo may have eaten its self) but all looked fine and it restarted drove it home but just wont rev properly.

had code for crank sensor so ive replaced this to no avail, no other codes at all????

if you keep messing about reving it you eventually get the code again for crank sensor signal implausible

swapped fuel filter for good measure still same driving me mad.
