    Posted: 11 Mar 2012 at 4:01pm
Hi, I'm a new member Dave Smith I have a 330ci sport 2003 Auto, I would like to know how to change the gear box oil, I have been told by local Dealer that it's sealed for life.
Any help would be much appreciated.
 
Cheers
 
Dave.

Oil is pretty straight forward, drain from the drain plug at the bottom of the box and refill from the refil plug halfway up the side of the box. Refil until the fluid comes out the hole.
 
May be worth changing the filter too.
 
To be honest, i have done this in the past, and for the extra £30 an independent would charge me to do it, i would let them do it on a ramp, as its not that easy on the floor.
 
Sealed for life is a BMW cock up, yes they will run for a longtime, but they do give up the ghost due to lack of servicing. Many 5 series owners will tell you that they have done hundreds of thousands of miles on the original box, because they serviced it!

Yes, in BMWSpeak 'Lifetime' means the three year new car warranty period, and a year cr two for the next owner!  BMW have not found an everlasting oil!  Changes at about 5 years of 50,000 miles are about right.

It's worth remembering to coat the tapered threads of the drain plug with thread sealent (NOT locking fluid) as otherwise you will have an annoying drip onto the garage floor.

I find that the stated capacities in the handbook do not always agree with the amount required to reach the level plug - my leak-free final drive was half a litre short - obvioulsy a bit of cost-cutting by BMW!

If you change the final drive oil buy some new aluminium sealing washers first, and if in doubt check that you have a limited slip diff by looking at the factory options list - a dealer will print it out for you free if you have the VIN code.

Look at the opieoils.com website for a selection of oils, such as:

Gearbox with yellow sticker - BMW Lifetime oil – LL1 or 2
Fuchs Titan Sintofluid SAE 75w-80 (as per original factory fill)
Amsoil MTF SAE 5-30 (SAE 75w-85 on gear oil viscosity)
Capacity 1.3 litres (ZF gearbox) See below for how to fill the gearbox


Final drive with LSD –
Castrol SAF-XJ.
Capacity 1.75 litres for 2.8 with Torsen LSD
(specified as 1.4 litres for M Roadster with clutch pack LSD)

Final Drive without LSD –
Castrol SAF-XO

Power Steering - Automatic transmission fluid
Capacity 600 cc

Many Thanks for all your advice, my local BMW dealer can change the Gear-box oil, filter and refil, and quoted me between £130-£180 dependent on which oil goes in the gear-box.
 
Cheers
