What is your question?
2008 audi q7 wouldn't start. Showed codes including cylinder 1 & 3 misfire. Replaced all spark plugs and cylinder 1 coil (could only find one new coil) and car started up prfectly. Twice. Put tools away, close up home and went to leave; it won't start again. Now shows all cylinders misfiring.
How long has your 2008 Audi Q7 had this problem?
A few days

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. With respect, much more testing is needed to find out why your vehicle will not start. Ignition, fuel and air must be checked for proper operation. Keep in mind that misfires may not be caused by one ignition components like a spark plug or coil. Those codes may also have nothing to do with what's wrong with starting. Seek guidance at a shop near you -- https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
