My volkswagen eos is getting wet on the inside when theweather is damp

Not enough info to properly answer but the battery in the remote might be dying and causing it to malfunction!

You either have water getting inside the car somewhere or more likely, you are keeping something in the car that is wet. As it is a 2017 model water leaking in is unlikely, (but still possible). Go through the car and check for anything damp and remove it. Lift the carpets and mats where you can and check them for dampness. If the dampness continues see if you can get the door rubbers checked under your warranty.

CHECK FOR WATER INSERTING INSID CABIN.IF OK LET ME KNOW

Normal at this time of year. You can buy a moisture kit from an auto parts store, or at a Walmart or similar type store. If you don't want to do that, wait till a sunny day and park the car in the sun with the windows cracked. It will help dry out the inside.

sounds like its time for tune up wires and rotor cap and such..with age they break down and moisture is shorting some of this out..to test this using a spray bottle spray these wire down and listen for a snapping sound from the coil..this is proof of the water getting the old wiers wet..(condensate moisture)

Go to your local parts store, buy a Di-Electric grease. It's not expensive. Pull each plug wire off one at a time. Take a screwdriver or something to stick inside the boot of the wire. Put this grease inside the plug wires on both ends, and also around any other wire you see that have a potential of getting wet. The keeps out moisture and really works. I did a friends VW this way and the VW dealership couldn't figure out what was wrong so this shuld help the problem.

Be sure that the screws that hold the wheel are firmly an uniformly screwed. Check if on the both sides you've got the same problem.

Damp is getting into your electrics. Spray all wires and disributor with WD40 after wet days or nights before trying to start it. That should cure it

I believe the problem is a leak in your heater core. The water would run down the inside of the firewall or near it thus running under the mat.
