E90 M3 questions

[KPAKKIRI]

Hi guys,

I have a few questions:

1. I've done 76k on my car, is it necessary to change brake fluid?
2. The diff is making a noise especially when you start up and drive a few km's. Should I replace with Rear Axle Fluid SAF-XJ +FM Booster (83 22 2 282 583)?
3. What's the best oil for the engine and how much should I buy?

Can all of the above be done by the local techie or who can I use on the East Rand?

1) If you brake fluid is dirty, which it probably will be, brakes must be bled and flushed for the change. Agents generally don't do a flush when you ask for brake fluid change
2) Not sure about diff
3) Liqui Moly 10w60 synthetic. Comes in purple can. Oil change, about 9-10litres
