Audi a5 3.0l diesel quattro experienced total loss of power. luckily had just come to a halt. engine will not restart. turns out the failure of main the main diesel pump destroyed entire fuel line system! audi quoted 13,000k replacement cost to change all 3 pumps, all 6 injectors and clean fuel tank! i am shocked. audi dealer said quite a few cases have occurred with the exact same problem! very disappointed that nothing has been done about this known issue. *tr
