2006 Audi A4 20T Quattro Sedan

2006 Audi A4 Quattro 2.0 L, 4S Car is not able to start currently. Not sure why but when described to mechanics on the phone, they said it could be a starter issue, crankshaft position sensor, alternator or battery issue (battery is dead after checking at Advance (7/7) . One mechanic was very sure it’s a starter issue but don’t know for sure since it’s not turning on. Potential oil leak. Salvage title. Title on hand. Fully tinted. Leather seats. Automatic 180,396 miles Comes with two sets of keys Airbag on driver’s side deployed (shown in picture) Trunk only opens with key (not with button on key). Sometimes when it drives it blows dark/black smoke but rarely. Could be turbo issue but not sure. Glove box is cracked and you need to hold on to it after opening but it does close. All I know about it. Selling as is. Can get it checked and fix the issues or use it for parts. You would have to get it towed because currently not turning on. Willing to negotiate on the price if you’re actually serious.
