NHTSA complaint #10748220, filed 2015-08, 60,000 miles“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.
