Hi guys, I am planning to change the engine oil and filters (oil and fuel) myself. Any tip on removing the oil and fuel filter? Do I need to buy the special oil filter removing tool or can I substitute? And diagrams of photos is much appreciated.

You "will" need the tool to remove the oil filter cap, £6 from halfords!!

When I was poor I used a long screwdriver hammered through the oil filter to remove it.
I don't know whether the W209 has access issues that would prevent that.

I don't think photos are required.....you simply unscrew the old one and screw on the new one.

I planning on doing mine as well. I have the tool for the filter and bought the the oil from GSF but bottled it at that point - I looked under the car and the whole undertray would have needed stripped out to get at the sump plug.
I think I will get one of those devices that suck the oil out of the top of the engine but I'm currently waiting on inspiration (and sun).

Really keen to hear how you get on.

I have a Pela oil pump and can highly recommend it. You could almost do the job in your work suit.

I suspect access to the oil filter requires getting your hands dirty though.

Thanks guys, I know better not to put a screwdriver through the oil filter as in this car unlike many others the filter is a paper one in a casing with a plastic cap so best to buy the tool from halford. As for the panels underneath, I am gonna remove them so I can access the sump the old fashion way. Still not sure where the fuel filter goes in this car? Any ideas anyone please.

After reading about other with engine cutting out due to maybe a bad fuel filter which was replaced, can anyone tell me if the Bocsh sold by eurocarparts part number 503220280 a safe replacement?

I 100% agree about the Pela pump..
I have used one for many years on lots of different cars.. It also has the advantage that you can use it to suck the old oil from the oil filter housing (something that wont be done with a conventional oil change !!).
1. Go for a run in the car and warm up the oil..
2. Remove dipstick (except in the case of some Mercs), and put the pela tube all the way down the dipstick tube till you hear / feel it hit the sump floor.
3. pump the pela 6 or 9 times and watch the oil get drained.. It doesnt take very long at all. I tend to release the vaccuum at about 3 or 4 litres and empty my old oil into a 20 litre jerry can, then re use the pela to finally drain the last of the oil. (The Jerry can I use holds enough for 3 oil changes before taking it to the recycling centre).
4. Just a thought on Mercs... Please make sure you are draining the engine oil and NOT the auto gearbox oil !!!

The Pela pump I use is here :

Hope this is a help

Hey Simon, I do agree with the above if the dip stick on my CLK270 CDI comes off! It did in my previous car, C180 Petrol but have a feeling it doesn't on this diesel version. Can you or anyone please confirm that the dip stick can come off without hassle so I can proceed as per your recommendations? Cheers

Hi Allmerc,
Your engine sounds the same as mine (270 CDI) in which case you need to remove the engine cover which is held on by 6 Torx type bolts (4 on the left cover and 2 on the right). It is possible to remove just the right cover but its a swine to relocate so I would remove the whole lot.
The engine oil dipstick tube is at the rear of the engine on the right hand side (Right rear corner as it were).
Remove the dipstick tube cover AND KEEP IT SAFE.

Don't forget to use the Pela to suck all the old oil out of the oil filter housing.
The Pela method works very well on this engine..
When I got my Pela pump it was supplied with a thin and thick extraction pipe.. I tend to use the thin one by default as it will go down all dipstick tubes..
Just remembered.. The only car it ever failed to be used on was a Cadillac Limo a friend owns..
I have used it on Vauxhall Astras, Various Golfs, BMW 330D, Rover 75, Peugeot 207 etc, etc.
I remember when I first bought it I thought I had been a bit extravagant with my money.. I can truthfully say it is the best car tool I have ever bought!

Thanks Simon, I certainly consider it...does this engine have a sump drain bolt too, like most cars? Just in case I go the old fashion way this time until I get round to but the pump.

Hi Allmerc..
Of course there is a sump drain plug. But to get at it you will need to remove the under tray. Thats one of the reasons I got into the Pela method.
Also if you are going to use ramps to get under it then I doubt you will be able to drain all the oil, but this does depend whether the sump drain plug is at the front or rear of the sump..
If its at the rear then you will be able drain all the oil.. If its at the front then putting the car up on ramps would prevent it all from being drained.

Another reason I like the Pela method is that your car stays on the level.

well, I drained the oil from the bottm, hard work and dirty...didn't manage to open the oil filter cap, too tight, but still put in the new oil for now until I get at the filter this wekend. I will go for the extracting the oil from the top next time.

Any luck with changing the fuel filter? I'm about to embark upon that this weekend!!

Be very careful. Do not under estimate the safety procedures in changing your fuel filter.

If you cannot afford to get this done in a workshop, be very carefull. You can and (likely will) get soaked in petrol.

Risk of fire and even death should not to be ruled out.

Ok, you're scaring me now.. what is it so dangerous? What do I need to look out for? Is diesel much safer than petrol in terms of its volatility etc.?

Hello Mercdriver, changing the diesel fuel filter is not a problem.
Pop the engine covers off, locate the filter, and have some rags ready to soak up any spills if there are any.
I have an early 270 CDi engine, the only issue I had was starting the car after I changed the fuel filter. These engines will not pump from the tank, as I found out the hard way.
Fill the new fuel filter to the top will clean diesel, and then re attach the hoses.
Please ensure that your battery is charged well, as you will have to crank over the engine a good few times to get the fuel moving, and the car started.

Thanks mate, for the vote of confidence and advice. It looks pretty simple. One question though, the hoses - do you just pull them off, or is there something you have to losen first? And silly question but, for that extra bit of diesel, do I get it from a petrol station even though its such a minute amount? Surely it'll cost like pennies?

Also, any ideas about the air filter? I bought one from MB today, but have not got the foggiest where to find it in the engine!! :)
