My bad, sorry is 13Ah 200A discharge. The resistance of mine says it will discharge 220A when tested so its in good condition is what I meant.😂
Talking of the pollen filter, tight wallets at Nissan did not change mine in the two year service for £450. I bought my own genuine Bosch for £20 posted. I normally change my filters every year as they are not expensive imho.🤐👍
I think I will pull the bumper off next year like you did and RTV around the headlight heatsinks after a clean to stop the moisture getting in. Glad you sorted yours out. I do like this car but its not without its faults. 😕

Any updates on adaptive headlight inoperative error? Did battery replacement fix it?

Hi , I recently bought a 2018 Q30 and it has the same issue (Adaptive front lighting system Inoperative, and High beam assist Inoperative). I took the car to the dealer and their first feedback was that the windscreen had been replaced with a non genuine one. They are yet to confirm this.

Resolved! My windshield has been replaced and headlight had a crack. Water came inside the headlight and damage the modules and some fuses. We replaced all bad fuses and installed headlight with the same part number. Error still exists. So I got a professional electric, he checked all wires and found that after replacing a windshield, someone mixed up 2 wires ( they looks the same but go to different modules ), he put everything where it suppose to go and it worked. Also problem sometimes appear after car sitting for a while, we checked a main battery and it looks like it's just old and doesn't provide enought power. Once you drive for 30 mins error go away.

Great to know that. would it be possible by any chance to know what are the 2 wires or how do they look like ?

My mechanic was working on it, so I'm not sure. But you can disconnect all wires in the rear view mirror area and see which 2 of them looks the same. But this resolution will apply if you mess with this wires before.
