https://www.aliexpress.com/item/4001100606264.html?spm=a2g0o.order_list.order_list_main.166.70b41802tnE6Oh I had this one in my Q5 for about 7 months and it worked brilliantly for Android Auto. I was even able to add a front and rear camera to it.

That kit only includes 7 litres, ZF say the box needs 8 litres

Interestingly, I can't see anywhere that ZF give any mileage recommendations. All they say is that - ZF automatic transmissions are filled with specially developed semi-synthetic oils. At very high operating temperatures, the oil ages faster than under normal conditions. Examples:  Many trips at high speeds  Many trips while towing a trailer  Sporty driving https://aftermarket.zf.com/en/aftermarket-portal/our-catalog/search-by-vehicle/#/ https://aftermarket.zf.com/app/controller/ti/download/Binary/22f16dae-c571-11ec-a2e7-00505690da53.pdf

https://www.thecarexpert.co.uk/rejecting-a-car/#1-can-you-reject-your-car-for-any-fault-you-find That link gives a really good breakdown of it. But basically no, you don't have to let them attempt a repair in the first 30 days but your PX'd car almost certainly won't be available to you, instead you'd be eligible for the invoice price of the car including TAX etc.

Oil is going to be leaking out of the engine somewhere, or being burnt inside of it, they're the only ways the oil level is going to drop. I'd go back to the seller (I'm assuming it was trade) and tell them your concerns, depending on how long you've had it will dictate what you can do with it. If it's within 30 days then you have a right to reject the car if it's faulty, not as described or not fit for purpose. 30 days to six months the seller has to attempt a repair or replacement but if that's not satisfactory you can still pursue a refund. Over six months it's all on you to prove it was faulty since purchase.

If you can't see an obvious dipstick then it's almost certain that you have a really helpful bung instead of one. I got an adjustable dipstick for my Q5 as it didn't come with one and I prefer it to trusting an electronic sensor.

I know I would.

Had Nextbase cameras like the guys above, the 422 and 512, they were OK but the batteries were done in less than 2 years. Decided to try something new when I got the Q5 - https://www.amazon.co.uk/dp/B0CVXDGNWP?ref=ppx_yo2ov_dt_b_fed_asin_title 4K front and 1080p rear, no batteries to ware out, can be hardwired or not, and (so far) has worked flawlessly. Even the software updates are nice and easy, plus the footage compared to my older Nextbase cams is a lot better.

^^^^^ agreed.

Was the engine at normal operating temperature when you did this?

I've been using the Noco Genius10UK for about 2.5years now and it's been fine with regular flooded cell batteries and the AGM on the Q5.

Faulty sensor would stop the gauge from working, but wouldn't stop hot air coming through the vents.

I think James means he's going abroad and leaving the car at home unused for 2 months. But you're right about AGM batteries, you treat them like any other car battery. https://www.yuasabatteries.com/resources/guides/agm-battery/

So, oil temperature is 73C but your water/coolant temperature gauge is sitting at just under 50C Possibly thermostat failed/stuck in the open position 🤷‍♂️
