okay vortex im gonna put this out there and see if i can get any insight to what might be wrong with my car.
Car: 03 VW GTI 1.8t
alright so here it goes... my car runs and drives fine during the daytime, i have little to no problems during light hours, but once it turns into night and i have to turn the dash lights on it seems everything goes to hell! there is a list of problems that happen once i turn the dash lights on(im gonna list them).
-sometimes when driving the headlights seems to dim and flicker every once and a while,
-when i flash my high beams the dash lights flicker,
-sometimes when driving the dash lights will turn off and come right back on,
-when driving sometimes the car will shut off for a quick second and then turn right back on(like if you would turn the key to the off position and then quickly put it back to start position),
-if i have the radio running it will cut off for a quick second then come right back on,
-also say that my windows are all the way rolled up and i lift the button to roll them up even though they already are the car seems to stutter and the dash and headlights seem to flicker,
-i have seen the EPC and traction control lights come on for a quick second before for no reason,

right now thats all that i can think of that happens, idk what it could be. i know the previous owner had the coilpacks changed because of the recall by the dealership, i took it to advanced auto parts and had them check the battery and alternator and they said everything was working fine. this problem is really pissing me off. i have no CEL or any other lights come on. for the most part the car drives well i just need to figure out what is causing these electrical hiccups. i need help and any would be greatly appreciated.

also ask any questions you might have... thanks
