Hey, only 2 turns from my driveway today my car popped a half check engine light. I restarted the car and it went away. I ran a scan tool and these are the codes that I was given can anyone give some insight as to what could be wrong :/. thanks in advance! https://imgur.com/a/Ob0ks

Try googling the codes and seeing what comes up.

On restart, the computer allows the engine to 'run' again, until the engine, for example, misfires enough to set misfire codes, which can shut down the cylinder. If you are stuck away from home, you can do this as many times as you want, but drive with care.

Most of the things that come up have to do with the vanos system. Being that there is no definitive answer I might just have to take it to the mechanic for a proper diagnostic.

So you would advise me to lay off driving the car until the issue is fixed to prevent further damage?

Had a mechanic look at the codes he thinks it could just be the crankshaft sensor having a bad connection to the computer. I've driven the car several times and it hasn't gone back into limp mode and seems to be running fine
