2013 Jetta didnt want to start this morning..??

About 25 degrees this morning. , tried starting car it would barely turnover? Radio lights everything came on . Let it sit for a minute then turned the key and held it while the engine kept turning over !
After about 20 sec it started and spittered for awhile yhen ran fine ... I added 4 pz pf Pwr Srvice whit bottle last fuel up , makes me nervous as i have a 100 mile commute each way ?!?!

Any idea what gives ?

Intercooler moisture buildup, aka Intercooler Icing. There are a whole slew of these posts in this sub forum. Long story short, if that happens, don't keep aggressively trying to start or you might bend a rod! Some people have it towed to a dealer.

Similar situation here. I started a thread on it so I will continue posting my findings. You may want to follow me there?
