Hi everyone,

I just bought a used 2007 Audi Q7 and a day after buying it we were driving and noticed some water dripping onto the passenger foot well. As soon as I turned the AC off the water stopped dripping.

It hasnt rained in the past week, and no water has gone through the sun roof drains (unless they washed the vehicle before giving this to me).

The next day I notice the check engine light is on and wont go off... anyone know what the problem could be?

We bought this from a Kia dealership that sells used cars, they said to take it in and they will fix the AC problem. Anyone know if I should be doing something else?

Should I be concerned about it being the sun roof?

I know this is a used vehicle, and has about 38k miles in it, but is this a bad sign? Having the water dripping and engine light on after the first day...

Thanks.
