• Okay so 2011 GTI 30K miles.

    Cant be bother to change my oil at this point in my life so went to a station. You know the kind you wait in the car while they do what they do. Long story short they left the coolant cap loose and two days later while having a spirited drive my car alarms for temperature and fluids simultaneously. I obviously pull over and after a few minutes of genuine confusion I fill it with water. I didn't make a huge litigious issue out of it because I figure good karma, waste of time, full warranty, etc.... They've flushed the coolant system and replaced the oil.

    I suspect it was truly running hot (>300F) for only a few minutes because I only drove 5 miles to work and back, before it alarmed on the faster drive.

    What would you look for and is there anything you absolutely replace? Spark plugs? etc?

  • I'd just monitor the car. See how it behaves over the next few days/weeks. If it's no different to what it was before then you've got away with it & lesson learned. If it starts acting up, not running like it was/should or you're conceded with anything, get it back to the garage and get them to do whats needed to correct.
