BMW F32 Axle Seals

Hello,
I own a 2015 428i coupe. I recently took the car to the dealership to perform a diagnosis on time chain, since they have an extended warranty for 7 years.

Couple hours later, of course I get bunch of recommendations from BMW lol:
- Replace Rear brake pads, rotors and sensor @ $830
- Replace both rear axle seals @ $1360
- Replace battery @ $476
- Perform coolant fluid exchange service @ $282

I will be replacing myself the brakes, rotors, wear sensor & install new battery (with registration of battery).
My question is what's up with the rear axle seals?? So expensive. Can someone give some insight on how crucial is that to be fixed? I have not received any warning on my dashboard. But the technician did share a video showing some leak around the differential. It seems too complicated to be a DIY project but i could be wrong.

Thanks

Seems a little high but not too far off IMO. I had one replaced under warranty and it took them about 4 hours. So let's call it 8 for two? but Where they get you is that the tools required to complete the job are pretty expensive and will negate any savings by DIYing it if you don't already have them.
I'd say if you don't have any noise from the diff and aren't seeing any puddles of fluid I would clean the area, top of the fluid and keep an eye on it for the next few months to find out if was indeed leaking or just lightly weeping. Good luck!

The seal is above the level of the fluid, so the most you'd have is a slight seeping. I lived with the same for many years in my e46...would just periodically (every year or two) check the level. Very slight loss; I wouldn't worry about it, but I would monitor it.

I had that issue on my 328d, took it to a BMW specialist Indy, cost $600 using BMW parts.
