Will try! Well, my fans don't spin even with ac on, but it's probably normal since ac doesn't cool and I have compressor and refrigerant fault in vcds. Need to have that checked too. Thing is, I couldn't find g83 reading anywhere in vcds, atleast in engine section, every coolant reading was g62 sensor, so that actually confused me.

So do you think I should stop being scared and all is well? Because my fear is that if the sensor is faulty it might read normal temperature on vcds and gauge, but in reality engine is hotter and fans should turn on at some point.. But even if that sensor is broken it shouldn't affect vcds readings probably?

Hi! I bought my 2007 Octavia mk2 2TDI PD a few months ago, and to my disappointment, it had blown head gasket. Week ago, I had my head gasket job done by local garage, changed thermostat, injector seals, gasket, bolts, head resurfaced. Heaters blow heat now and all looks well. But I just remembered that before I got my head gasket fixed, I've never really seen my radiator fans spin at 90c on gauge. Now I checked it multiple times, i still couldn't ever see them spin. As I was worried yesterday I picked up vcds to make a scan to be sure. It threw g83 sensor fault, signal too high. As I've read, it actually controls when fans turn on. I thought I've found the culprit, but decided to clear codes and drive a bit and look at coolant temp in vcds. On idle it didn't exceed 86 ever, when I drove max I've seen it reach is 89 and g83 fault code hasn't appeared yet. When operating fan test with vcds they both spin, so they are good. So my questions are: 1. Could that g83 fault been thrown only maybe because of all that head gasket fixing and all is well with the sensor since after clearing fault and some driving fault didn't come back? Drove like 30 mins tho. 2. Is my coolant temp on 5-7c ambient temp normal on idle, some town driving and fans aren't really supposed to run on this weather? Can't test on normal roads, because of covid we can't leave our city..:') I'm really being paranoid right now, because I soon will have about 700km driving to do and I don't really want to blow new gasket again if it's reading incorrect temperature and because of that fans don't come on when they are supposed to. Sorry for bad sentence formatting, my thoughts are all over the place right now..
