why did my audi a4 just completely die on me while driving?

could be a number of things but my best guess would be the fuel pump has gone out on yea. Turn your key and listen for the pump buzzing noise. if its threre check your fuel filter. if you been not using any type of quality gas it coulda clogged your fuel filter. anything after that would be blamed on either sensors or spark.

What was it? Having that Same issue

I have a 2007 Audi A4 (Quattro) that won’t start anymore, I was driving and it died. The lights work everything works, sometimes it cranks but dies right after. I forgot to change the filter the last 2 times I changed the oil. But after the car dies I hear a lot of fast clicking. I think it’s the battery or alternator (my battery used to dies a lot when I got a aftermarket radio and I’m almost sure there’s a parasitic drain bc I can charge my phone with the keys out and turn lights on play the radio etc) does anyone know if it’s the battery or alternator?
