Hi, dads turbo went on his TDI 170 Audi A3 which had a fault that was under boost now the turbo has been replaced he's now getting over boost? Can put your foot down and it won't even get to 2k rpm sometimes it will, Isn't drivable as hasn't got any power whatsoever and when you do rev it, it chucks out lots of black smoke
any ideas guys?
