It's real easy, Jack the car up, Axel stands under the LWB's.
Remove plastic under engine tray, stick you head under you'll see the turbo, follow the pipe you'll have a nick / hole right where the engine earth bolt it, no doubt.
Two clips the pipe will come off, easy peasy, pop a new one on, new jubily clips or similar, just rotate the pipe slightly to stand it off the bolt.
If you real keen, you can take a grinder the end of the stud for the earth bold, or cap it to stop it happening again.
AR redesigned the Turbo to intercooler pipe, because... you guessed it, it rubbed against the pipe. So all new pipes (like 3 years ago) are slightly different shape.
Can anyone give me any pointers on this particular pipe? Mines a bit smokey too under acceleration.
