2012 Audi Q5 won't start after sitting in the sun for an hour or more
Our 2012 Audi Q5 2.0 Quatro (114K miles) would not start. I called AAA and
they stated the battery was dead. They replaced the battery. Five days later
it would not start again. I took it to the Audi dealer who ran a diagnostic and
determined the alternator and starter were fine. The spark plugs were
replaced three months ago. They determined that the battery AAA installed
was not the correct one, and was not correctly coded to the car. They
replaced the battery with the correct one and coded it to the car. Two days
later the car would not start again. It starts every time it is in the garage or in
a cool place. It does not start if outside in the sun for any length of time. We
can get it to start by simultaneously stepping on the brake and then giving it
gas. That works, but is not a solution. The Audi dealer is baffled. They can't
find any codes when running the diagnostic. We recently moved to a high
elevation (5,900) and the problem started shortly thereafter. We only use
premium gas and have also tired adding an octane booster and a fuel
cleaner. We need some help figuring this thing out. Thanks!
