This one is narrow enough at the bottom to fit securely in (and is only a tenner). Different colours available of course. Works well for me - I'd recommend.

They basically just sit on the floor beneath the seat. Wife's out in the car at the moment but can upload a photo tonight

If you want storage under both front seats, and don't want to buy and fit the official add ons, I can recommend simple Ikea Drona boxes which I've been using successfully for around a year. They don't slip, and fully utilise the space under the seats (hold just over 6.5l each). I use them for snacks for the kids, and a box of tissues etc to avoid cluttering the cabin. They fit perfectly. These ones on Amazon if you don't have an Ikea nearby. I should probably point out I don't have electric seat adjustments which means there's room. I'd guess if you do have that, there wouldn't be room for the storage. Hope it helps someone.

I have this exact same issue. After all the usual trouble shooting steps, I have connected the car to the house wifi, where it has strong signal and it still doesn't work. I've tried setting up a variety of different accounts, uninstalling, reinstalling etc but no luck. If a garage tells me it's anything north of £100 I won't bother. I bought the car second hand so wonder if it's some sort of hangover from someone else previously having the primary account?

I know this is a bit of a dormant thread but I recently had the same question and found the answer in the Bru Travel Mug which I saw recommended here. It fits in the cupholder and holds a good amount of liquid. Would recommend and thought it might help others.

A bit on the pricey side but not much more than other travel cups. And personally, I prefer that to an additional lump of plastic needed to accommodate larger bottles/cups.

A bit late but I've only recently encountered the same problem after buying my car, and this might help someone. I bought loads from Amazon (their listings don't always seem to have accurate diameters). I returned most of them but kept this one which fits perfectly. Holds a good amount of liquid and fits in the cup holder snugly.

I bought a 2021 Octavia recently. Love the car, hate the cupholders. I bought about 10 cups/flasks from amazon to find the best. I kept this one and returned the rest. Can recommend. It's a really good travel mug, looks great, and fits perfectly because it's much narrower at the bottom.
