I've got my new turbo booked for next week. Gone genuine.
Had a real problem with the 3420 handler last month and I think if it wasn't standard the dealer might have just walked and left me on my own with it !!!
We don't have much luck with local dealer there not very helpful so we try are best not to use them, even the parts are dearer than the next dealer
But I've found the same turbo unit for £400 cheaper so far and there new with no exchange
