THIS MIGHT HOPEFULLY HELP SOMEONE- HERES HOW I CHANGED THE OIL IN MY 2001 2.5TDi 88hp T4. IF I CAN DO IT- ANYONE CAN! SERIOUSLY!!

Tools & things you'll need-
VEHICLE JACK
AXLE STANDS (My van is lowered by 60mm)
REPLACEMENT OIL FILTER (ahem)
5 to 5.5 LITRES OF GOOD QUALITY OIL (Usually i buy best i can afford like Castrol or Mobil etc etc but differentpepople swear by different oils- choose one that is at least what VW spec!)
ENGINE FLUSH TREATMENT (wynns or similar) THIS IS OPTIONAL!
10mm, 13mm, 19mm, 27mm & 30mm SOCKETS (These are what i needed on my van- yours may differ!)
CATCH TRAY FOR USED OIL (i use an old plastic washing up basin bought for ÂŁ1 in Asda/ Poundland- make sure its at least 6 litres to safely catch oil without overflowing- VERY BAD!!!!!)
OLD RAGS TO CLEAN OIL OFF HANDS AND ENGINE
STRONG PLASTIC BAG FOR OLD FILTER & OILY RAGS ETC.


Firstly- give your van a run to get it up to temperature (90deg) and the oil nice & runny, then i always add an engine oil flush treatment - directions on tin- and take another 15 min spin to get it working around the engine.
Park on a FLAT surface and let the engine cool a little bit to stop you getting scalded.

I usually start by opening filler cap in engine bay- gives a good flow when you undo sump plug under van.
Jack up your van both sides and place axle stands underneath at SOLID jacking points- i always use standS- its suicide just working with only the jack supporting your van!!!
If you have a protective tray/ shield under engine/ sump (as i have) undo the two 10mm nuts supporting the back of the tray.
These are REALLY small and INSIGNIFICANT looking, but are vital as they stop the tray from dropping down on their pivots.

Image




Undo the 4 x 13mm Bolts (2 each on either side if van in wheel arch space) These are more easily identified, as you will see from pics.

Image


Image




The tray will now drop down at front of van- i had to pull my bumper out by a few mill to allow it to drop fully.
Wiggle the tray around, pulling down and back until pivot supports drop down, allowing you to remove tray from under van completely. (This is a bit of a pain in the :* a*se if its raining and your lying under the van- i need a bigger garage!:()

Image




Now the SH*TTY messy horrible part (I strongly advise a pair of rubber gloves for this bit!)
Crawl under the front bumper, and ith your feet pointing towards the front of the van you should be able to identify the oil filter at the back of the engine (usually black & shiny), around the area that sits directly under the drivers seat.

Image



Check what size the nut is for your socket. I had a MAHL filter on the van which is 27mm socket size and my VAG replacement is 30mm!! (Cue trip to Halfrauds :bhd)

Image



Before you undo the filter (all you want to do is identify what socket you need!), locate the sump plug (see pics- usually on lowest part of engine case, on rear facing back towards rear of van).

Image


This is 19mm on my van.
Put your catch tray (basin I:) directly under and back of this as oil will SHOOT out at first in direction of back of van. Guranteed you'll get caught out if first time- we ALL were!! (Keep rags handy!)
Undo your sump plug at first with your socket, then by hand, as you NEED to catch it before it falls into the old oil. You REALLY dont wanna go fishing for it!

Drain your oil A: I usually make a brew and take it easy for 30mins while this happens, making sure all my old oil drains out. It makes putting the sump plug back in easier too ;)

If you've been clever you'll have caught the sump plug along with the copper washer- i usually just clean these up and re-use (although many will disagree and say buy a new copper washer- iv did this for YEARS without any leaks! Make sure the washer isnt warped or nicked etc & it'll be fine.)

When all the oil out, put the plug & washer back on to the correct torque (not too tight- you'll strip the threads. I usually do it hand tight then nip up a quarter/ half turn).

Now move your old oil out of the way & undo the old filter. I used a 3" extension piece on my ratchet.
Take the filter out VERY CAREFULLY, holding it as upright as possible- its full of hot oil.
Pour old oil into your basin and put the old filter into your plastic bag to stop any mess.
Clean around your engine and most likely oil will have run onto the axle etc etc- its inevitable!

Now take your NEW filter, HALF fill it with new fresh oil. HALF fill because you have to angle the filter to get it on the thread and when full, oil will tip out (I learned the hard way!)
You dont have to put oil in the filter at this point, it just helps get it round the engine quicker and gets the level sorted quicker too.
It also helps to smear a tiny bit around the rubber seal.

Now tighten the new filter on the thread till hand tight then put your socket on and nip up about a quarter/ half turn- dont tighten too much- it does more harm than good!!!!

A:A:A: HARD BIT OVER A:A:A:A:

Pour in 5 litres of your oil (or whatever your engine takes- REMEMBER this is based on MY van not yoursI:)
Check where oil level is on dipstick & top up as necessary so it sits just below the top/max notch.
Run engine for a few mins to let filter fill up properly, and allow oild to flow around engine then turn off & leave oil to settle back into sump for 10mins.
Then re-check oil level at dipstick & top up as necessary.

DO NOT FILL ABOVE "MAX" LEVEL ON DIPSTICK- YOU'LL INCREASE OIL PRESSURE & BLOW SEALS

Run the engine again until it reaches working temperature, turn off, crawl under van and make sure no leaks from sump plug or filter (tighten to suit).
Re Fit the engine/ sump guard and Jobs a goodun A:A:A: (Just keep an eye on leaks & levels after next few journeys)
ÂŁÂŁÂŁ's saved


PLEASE POUR YOUR OLD OIL INTO YOUR EMPTY CONTAINER AND TAKE TO LOCAL RECYCLING POINT- ITS SO EASY TO DO.
DRAINS ARENT FOR OIL- IT F*CKS UP THE ALREADY SH*TTY SEWER TREATMENT SYSTEM & POLLUTES WATER SYSTEMS.
I GOTTA SURF IN THAT SH*T!!!! :eek:

Hope this helps.

Very interestingA:

Liking the pictures.

Well done.

Cheers Rob
Comments appreciated, Thanks!
I know its pretty simple stuff compared to a lot of the Tech issues on here but its good to give something back to the forum rather than just taking, seeing as im a newbie!:D

Re: Change your engine oil & filter (pics)

Great guide.
I followed it but got stuck when it came to taking the sump drain plug out. Mine is stuck fast! Has anyone got any tips for freeing it? Does the engine temperature make a difference?
Cheers,
Will
Use a breaker bar on a socket! The longer the bar the more "purchase" you'll have for breaking the seal (I STRONGLY recommend buying a new replacement copper washer as it sound like your nut has been overtightened). Brute force is probably best approach here!
You should be changing the oil after your engine has been up to temp so your oil is hot/ warm anyway, as it thins and drains easier from all the nooks and crannies.
Hope this helps?T:

Re: Change your engine oil & filter (pics)

I followed this guide and changed my oil and filter this morning - found it a great help - Thanks

Only difference on mine (a 2002 2.5tdi AJT) was the sump plug was 17mm

I found you definately have to use a socket to get the filter on and off - I tried using a 27mm spanner at first but there's no room in there to move such a big spanner - I had to rush out and buy a socket - good job we've got another car !

Couple of tips...

DON'T undo the filler at first...remove the sump plug 1st, the oil will not "gush" out as fast, so you get a better idea where the washing up bowl wants to be....THEN slowly remove the filler cap (always worked for me....just means an extra trip up and down again).

Also...the filter...twice now I've had leaks from it after a garage changed it. (Warrenty jobs from where I bought it).

When I came to do it myself, I found it was almost LESS than hand tight...no tools needed to remove it at all!...no wonder I had oil drips all over my drive.

A certain Mr. Baxter told me it's very common...
Tighten it up as tight as you can...MORE than the "hand tight and an extra half turn"

When I bought my van & did the first oil change the filter was so tight the hex. part sheared off at the spot welds. As mine is a syncro it's very tight in there & I was lucky to eventually unscrew it. I have never had this problem when I have installed them but I have had problems with leaks particularly if you have oily hands. I now use a torque wrench set at 20Nm or whatever is written in the filter. No more problems.

Hallo Ty
just wanted to say a huge thanks for taking the time to post this guide and the fuel filter one. they have been excellant, and after 30 years of going to mechanics this afternoon I successfully serviced my new VW 2.5 T4 ex AA. I feel very proud. And thanks to your helpful warnings I am not covered in oil!!!!
Only comment is that my old oil filter had no nut on the bottom so I had to borrow a gizmo from a neighbour. the worst part of the operation was changing the air filter!

Many thanks Twoz!

I was feeling an utter idiot when I couldn't find the oil filter on my ´98 2.5 TDI. It is extremely well hidden away. Fortunately I have access to a grease pit which helps, but its still a beast to find if you don't know were to look! The previous owner/VW garage (who have done all the servicing previously) have conveniently left the sump guard off. Good for access, but maybe no so good for the vunerable looking electrics hanging down low and possibly the engine noise level? Maybe I should scout the local breakers for one?

Very Useful guide

cheers mate!!

however my oil filter was a complete to get off!
- first I used a strap wrench and it wouldnt budge after 3 hours trying!
-then the end hex sheered off when I tried using a socket,
-eventually I managed to drill a hole in the side and worked a screw driver in to use as a unscrewing handle. After hours of perceveering It started to undo.
(note: I had to apply constant turning pressure for a good 30 seconds)

So now ive put the new filter on and theres a leak

only hand tightened then as advised used a socket to do the quater turn

ran the engine and oil was ing out of the filters seal

tightened again a little bit and tested and it became more of drip than a

repeated this proceedure numerous times and now I have a very small drip ( 1 every ten mins) and cant tighten up the filter any more

Note:
- as you can imagine I was very jubious about tightening it up more than reccomended(but because it made a positive difference, so I carried on)
- I did clean the plate that the seal would sit on
- I did run a little oil around the seal before applying

Is this kind of leak a problem? a mate said sometimes it clots itself and stops the leak after the system has heated up and cooled down a few times
has this happened to anyone else?

Can anyone suggest a fix?

thankyou kindly

from an english man in the outback.....well......sunshine coast!

Great guide. Thanks for posting this.

Ive always taken my cars / vans to the garage to get oil change or servicing.
But felt confident in following this - and no problems at all. Saved myself 50 quid at least!

A friend offered to loan me his small ramps, and that made it really easy.

Inspired and confident, tomorrow i will replace my indicator stalk to add the cruise control using another how to guide. T:

Great write up on all the air,pollen, fuel and oil filter changeover. Got all mine done on my 99 t4 2.5 tdi.here are my experinces/findings.
Fuel filter . Pretty simple apart from difficulty at getting 2hands/arms down into the small tight gap.
Didn't fill the filter with fuel so it took 2 or 3 good long turnovers of the key to get it fired.

Air filter. Remove the screen wash bottle neck with a quarter twist , remove 2 screws from the hose going into the filter box / remove the hose. Undo the 2. Clips to the air box
The hardest bit is getting the box top out of the engine bay . It just takes patience and a wiggle here a wiggle there. The same getting back on.

Pollen filter . Really rubbish clips to re clip the pollen filter to the backplate housing . The clips are as follows . The 2 sets of clips that are the same clip in at 8 o'clock and 12 o'clock as if your looking at the housing and the flat clip is at 4 o'clock.
Refit the darth vader helmet cover.

Oil filter . Original filter was 30 mm socket which I removed using a standard 1/2 inch ratchet but with the multi angle elbow piece that comes with the socket set
The new filter was 27 mm socket

Oil sump plug. Absolute pig of a job.
My sump plug was at the back of the sump facing toward the back of the van.i chewed the nut with my standard 12 sided 17mm socket and it would not shift. So I went to Halfords and purchased a 6 sided black impact socket . With my bus only up on axel jacks and me on my back a couldn't get any leverage ,and as my plug faced backwards , a breaker bar was too long to get in between the bottom of the van and the ground!!
To get the plug out , I had to heat it up with my mapp gas blow lamp ( was crapping myself because of the alloy sump ) and then using my new socket on the standard rachet bar , batter the bar with a lump hammer!!!
It took me a good half hour of heating up/ hammering , heating up trying , heating up , all the time thinking I'd gone past the point of killing my van sump then with one last hammer ... Crack , the sump plug loosened off . It was literally finger tight once I made the breakthrough but the plug was well past it and needed replacing .
With hindsight . I would not have knackered the plug using the 6 sided socket, a breaker bar and either had the van up on a ramp or over a pit to get some downward leverage on it although,having the front of the van on axel jacks helped the oil drain from the rear facing sump better than if the van had been level.
