Qashqai Fog Sensor Fault

That sounds incredibly frustrating! I have a Qashqai too, although I don't know if the newer models are very different. I had some weird electrical gremlins a while back, and it manifested in some bizarre ways. Have you noticed any other electrical oddities? Like, any flickering lights or the infotainment system acting up? It could still be the sensor, but sometimes these things have knock-on effects. Did you try clearing the error memory to see if it comes back?

That's interesting! No flickering lights or infotainment glitches that I've noticed, thankfully. Just this collection of fog-related malfunctions! I did try clearing the error memory, but the fault reappears almost immediately after starting the engine. You mentioned electrical gremlins - did yours involve anything similar, and how did you end up fixing it? Maybe there's a common connection?

Okay, the rapid reappearance of the error code points towards a more persistent issue. My electrical problem was different – my driver assistance system was going haywire, constantly beeping and flashing warnings for no reason. It turned out to be a corroded connector in the bumper. Given all the symptoms you're describing, especially with the air conditioning and mirror heating being affected, I'd say you're right about a cable or connection issue being the likely culprit. To be honest, with that many problems, it might be worth taking it to a workshop. It's hard to diagnose electrical issues without proper tools.

Thanks a bunch for sharing your experience! It's good to know I'm not alone in this Nissan electrical madness. You're right, probably best to get a professional to look at it before I make things worse. Dropped it off at the workshop, they confirmed it was a faulty connector to the fog sensor, just like we suspected! Total cost was 95€ including labour. Appreciate the advice!
