With no sump plug sucking the engine oil out is the only way on the 3.0l D4 but has anyone done it on the 2.7l D3 via the dipstick hole? The End

So the D4 has no sump plug, that sounds stupid, why is that? Never tried sucking the oil out through the dip stick tube, but it I would imagine you would need to take the oil cap off aswell otherwise you'll might create a vacume. I think the dopstick hole is pretty small to pull the oil up through, sounds like a nightmare. Changed the oil in my D3 today without any hassle. D3 HSE MY05 Auto

I watched TFC use his 'sucking' apparatus to change the oil on my previous D3. Very clean and hassle free.
BUT when I looked over a D4 the other day, the salesman told me that there was no dipstick anymore, the levels are checked electronically and viewed in the message centre.

The 3.0l TDV6 has an oil extraction tube, no problem using commercially available oil vac. pumps on the 2.7l TDV6

Trouble is with oil suction kits is that it doesn't remove any debris that is sitting in the bottom of the sump. Also with draining the sump, you can see if bits are breaking 
We used darlek type oil suction systems at two workshops I worked in and they took too long to remove the oil, so they were left in the oil stores. Suppose they're alright if your not working to book times for servicing

Even just sludge gets to stay on the bottom, as evidenced by the number of Saab engines that have gone bang with insufficient oil being pumped in engines that don't get used much. 5 yrs & 50k kms and watch out! Way out of warranty though.

I still have an oil pump from when i worked on forklifts...Due to ground clearance issue's we always sucked the oil out,much safer than jacking it up and laying underneath
The sludge etc. left in the bottom of the sump should be broken up by the new oil and then the filter should do its job. If you were worried about sludge build up im sure you could run your car with some engine flush prior to sucking it out
Ive never had a problem with good quality oil's sludging up

Has anybody tried the QR oil plugs (as sold by http://www.uniquetruck.com and no doubt others too). I thought long and hard about getting one of these for my Isuzu Trooper because it had a ridiculous oil changing regime - but I decided to trade it for my D3 so 7 litres of synthetic 5-30 every 3000 miles is somebody elses problem.
I tow regularly so oil changes are more frequent than driving solo. Any method of making the oil change mess free has got to be worthy of consideration.

I purchased a boat oil change vacuum sucker and have used it on my D3 and BMW X5 a few times. They were developed for boats as you can't get to the sump plug in most inboard runabout boats and small cruisers as the engine sits in the V of the bilge, it is standard practice to suck it out and has been so for years.
The idea for the D3 is not to have long oil change intervalls so that sludge accumulation is minimised
I had to lengthen the supplied tube as it was not quite long enough to reach the bottom of the D3 sump.
Two diameters of tube are provided and the narrow one allows air back into the sump as you pump out, as it is not a tight fit in the dip stick hole.
If you change the oil frequently and after an engine run, then any sludge should be liquified and sucked out.
Anyway in Australia most boat shops (Whitworths) sell them for about A$100. Mine has 6 litre capacity and is Italian.
On both the D3 and BMW the filters are on the top of the engine so you can do an oil and filter change without getting under the car, very convenient.

I have used one on my TDV6 every time it comes back from service, when they put half a litre too much oil in.
It works a treat. Arctic Frost Discovery 3 TDV6 SE, Active Rear Diff, Adaptive Head Lights, Tow Pack, Ebony Leather, Roof Rails, Mantec Guard. Tasmod Stainless Sill plates. Grabber AT's. Home made mud flaps. Side Steps back on until the next time.

Boat engines run for years without the engine being drained through a sump plug and they spend a lot of time sitting around as well.
I think if you change the oil regulary it is not an issue, plus the engine is always warmed up so the oil is thinner and easier to remove.

Does that tube look like it'll take a D3 style dipstick?  Dr. Ian Malcolm:

I have bought an oil vac. I have found the smaller tube is only a metre long and it is not going deep enough into the sump, on my disco 3 2007 2.7 engine. hence not working
Tried it in old oil in a bucket and worked
Can anyone tell me if the dipstick hole has to be sealed, myself I do not think so
Has anyone else had this problem of extracting oil out of 2.7 engine

No, you can't do that sadly
