but dont be hopeful, those diesels have a turbo heating upto 900-1000 degrees frequently, pressured air lines, intercooler, wastegate, related sensors and controllers.. which is not existent on a na car.. and personally I wouldnt bet when they will fail
Well they don't on a diesel though CEM, the exhaust temperatures are much lower than petrol engines (you have to work hard to get them up to 500-600 degrees to regen DPF's.
Of course no waste gates either and the only other sensor is a manifold pressure sensor which is pretty bomb proof (might want cleaning every 50K miles).
I should add we have an Insignia diesel Auto and a few others including an A4 2.0 diesel auto here at work. I am no fan of the Insignia as it has a few to many fundamental design issues (particularly the hatch back) but the Insignia knocks spots off the A4 and is pretty smooth to drive (but annoying when you use it in semi auto and it comes up with 'shift denied' because the resulting engine revs will be below 1500rpm)
