Hi, sorry to everyone that I have not replied but my Laptop went up in smoke, everything breaks at once!!!! I got my landy back and took it to another garage who passed the MOT and no mention of a 'knackered turbo'. Car is driving exactly the same as it always has been and I will keep an eye on it though. Thanks to all for your advice it has saved me £££s.
bad turbo yes 20000rpm and lack of oil or not letting it idel before shot down causes this for lack of oil pressure not pretty when they blow john w usa
