tdi 110 turbo cut out

[a.barnard]

Hi new to this so hopefully someone can help, my tdi 110 has covered 150000 miles with few problems but now on acceleration the turbo cuts out, can only get it going again by turning off the engine and starting again then its ok, took it to vw who replaced the boost switch ? it was ok for 6 mths then started playing up again, any ideas?

Get a fault code read.
It sounds like overboosting which can be caused by a number of things.
The code read will help with diagnosis.
