Oil change do i need to remove the large plastic tray to get to the sump to change oil and oil level sensor on bmws

Pull oil dipstick. Remove the drain plug from the oil pan. Once that is empty replace plug. Then remove oil filter. Replace filter by filling new one half full with oil and smearing clean oil around the rubber seal on the filter. Reinstall and fill with engine with appropriate amount of oil. Confirm oil level on dipstick. Start engine and monitor oil pre and check for leaks. Recycle used oil and dispose of filter properly.

You need to remove the sump pan off the gearbox but what looks like a drain plug on the sump is actually a gearbox filler level tube. You may also find a drain plug on the torque converter. Remove the sump pan and you will find the filter screwed to the bottom of the valve body The problem you will face is filling the gearbox oil to achieve the correct level a computer is needed to measure gearbox oil temperature. With the gearbox oil at 30 centigrade you need one drip out of the filler level every 10 seconds.

You will need a sump plug removal tool.
On older vehicles, this was just with a wrench.
But it could be a special key, check the plug on the base of the sump.
Take keys from ignition (as you do not want to accidentally start an engine with no oil.
Open the oil filler cap, place a container under the vehicle (could be quite a few litres of oil to come out) and remove the sump plug.
Leave the vehicle to do this for a short while, until it all stops dripping out.
Now you would want to change the oil filter.
These are in different location, but you can get a filter wrench to wrap around to remove.
PRE FILL the new oil filter with clean oil before installing (This stops any air locks when you start the engine after the change)
Hand tighten the new oil filter, they do not need a great deal of torque to screw in place. so generally a good hand tighten is enough.
You may need a new washer for the sump plug (some oil filter kits come with this in the box)
Now that the new filter is on, and the sump plug is back on. Fill the engine with the correct amount and type of oil.
I do not know the exact amount you will need.
But it is better to fill a little at a time, check the dip stick for the correct level.
When you are at the correct level.
Run the engine for a few minutes at IDLE.
Stop the engine and check the oil level again.

You should be all good after this.

Also check again after a few miles, that the sump is not leaking, and that the oil filter is also not leaking.

Or take it to a dealer....

the long answer is...put engine flush in oil, run for about 1 hour,switch off/remove key,then remove splash guard from under the engine (best done when car on ramps)then remove oil filler cap and drain plug on sump(oil pan).whilst draining into an empty can with the side cut out(drip tray) locate oil filter and punch a hole in the side of it with a screwdriver,and unscrew it.
Wipe oil onto the rubber seal of the new filter and screw onto carrier.hand tight only.
then replace sump plug washer(copper/fibre)and replace using a 6"long ring spanner and do up tight.
(max pressure of palm of hand)
put in about the same amount of oil that came out,replace oil filler cap and start engine.
check for any leaks,replace splash guard and lower car to level surface,turn off engine,leave for 60 secs,then dip for oil level and top up to midway on dipstick,
job done....
use 10/40 semi synthetic oil.

if you put a large dent in the sump you have increased the oil level hight inside the sump above the dipstick mark,replace asap...

allen key sump plug in middle of flat sump pan to drain the oil, and a filter removal tool to remove the plastic oil filter housing positioned just forward of the sump. Refill with 8 litres of oil via the filler tube, run till hot then leave for 2 mins before checking level via the instrument cluster

Remove allen key drain bung in centre of flat sump pan to drain oil, then using oil filter removal tool unscrew plastic oil filter housing situated just forward of sump, replace filter and sealing ring/washer. Refill via filler tube 8 litres and run engine till hot. leave for approx 2 mins and check level via instrument cluster (job done and saved £200)

Remove the large plastic body panel under the engine, if it is still there. The oil pan is about 14in x 12in square with a round sensor in the middle. Drain the oil, disconnect wires, remove all 20 or so bolts. Clean gaskek surface and silicon new gasket in place. replace the bolts, but only hand tight. Let the silicone set for 2 hours, and then tichten to factory spec, about 15in/lbs
