Hello. I recently bought a X1 20D auto, 2012 with 8k miles on it. I'm thinking I have to change the gearbox and transfer box oil/fluid purely because of the age of the car. BMW dealer stands by "seal for life" crap but I'm not sure what to think. It's basically 12-13 years old fluid in there. I've read previous posts about ZF recommending at 60k miles for gearbox oil and 30-60k for transfer boxes fluids. In my case, at 8k miles do I need to change it? Thanks 👍

Welcome to the Forum

Your Gearbox is ZF GA8HP45Z which I believe ZF advise should be serviced every 60 to 100000 km dependent on environment and use (Climate Towing etc) If you feel like teasing your local BMW Dealer service manager ask him if it's sealed for life why do BMW have a gearbox service kit on their parts list 😅 Transfer case is ATC 35L

Personally if it is running well and at the low miles you have it isn't an urgent priority. 12 years is a stretch I would look for a good Independent or better a ZF Transmission Specialist if you can't DIY

Hi Dave, thanks for the reply. I've only had the car for 2 weeks and so far it's running good, i could probably diy-it but I've not done it before so the missus won't let me🤣( it's her car) . Local BMW dealer quote me 830£ for gearbox service and 550£ for transfer box/boxes service. Safe to say I told them I'll sleep on it for a bit😁

      I’m guessing this one hasn’t been serviced since it was born! … I took the filter box apart and it needs replacing. Someone has tried to fix it before, but it’s beyond alive now! Haha. the bootlid needs either pushing out or replacing, as does the rear bumper after it got into a fight with a bus… and a rear light… apart from that, it seems well. 😂

      Inherited an R56? 2009 ONE

      Great little cars Stu A neighbour has one and she loves it they do need a good annual service though, seen several that were unreliable due to not being used much and waiting for the service indicator to tell them it needed service? One was 5 years between services? You will also need a good code reader Dave

      Inherited an R56? 2009 ONE

      Well… we have a freind at church who has been struggling with the car and I haven’t ever had time to look at it. So, we upgraded the Peugeot to a Porsche and felt it right to gift her the Peugeot. in return, I have taken the mini and intend to spend some time on it before gifting it to someone else who needs a car. drove it home and it had more lights than Blackpool.! spent an hour or so tinkering and I have got it down to two issues. The air filter needs replacing and it is showing a code of 2983 inlet cam sensor. im going to order me a Bosch one and hopefully the engine will run a lot better… after its had a tank of redex! any other suggestions or things I should look for?
