2010 audi a4 doesn’t want to turn on
I have a 2010 audi a4 and it doesn’t want to turn
on. It is not the battery because we already
checked it. I don’t know if it could be because the
fuel tank is clogged. It could be because the gas is
the extra gas of 89 and not the premium of 91. Can
someone please explain to me what can i do?
Thank you!
