When the engine pings, it will sometimes throw a misfire code. My 1.8T does it too.

HAD the same DTC's before. Only once though. It was a month after using 91 octane for me.

I had misfires for quite a while..

They regularly tripped the check engine light, which would then go away a few days later.

One dealer couldn't fix it twice and told me to make sure not to run the car really low on gas. Since I don't think I'm any worse at running low on gas than the next guy, I dismissed that advice.

I took it to another dealer who diagnosed a faulty coolant temperature sensor. Problem hasn't happened since.
