Hey all, new here. Figured it was time to come on here and ask a couple ?’s.

So I’ve had my TT for almost 15 years now and it’s been a great car to us, just over 150K on it. I’ve had the cluster fixed but still getting some problems.

Ok, so anytime I turn on the headlights my oil light will come on and beep at me, I can turn the lights off and it goes away after 30 seconds or so. Also, I get random buzzer sounds like I’ve left the lights on or key in ignition while driving, a bit annoying. I’ve also recently started getting the temp gauge out of nowhere shooting way up and the water temp light coming on even though my temps are just fine (have an UltraGauge installed) Battery was replaced recently, Alt done a couple years back and charging numbers are good. Is this just a case of bad connections throughout? I know VW/Audi kinda chince out on soldering and such.

Any ideas on possible fixes?

Thanks for any advice!!
