Good evening people, I am new to the forum and have inherited from a relative a c180 kompressor coupe 53 plate

I have searched the forum but cant seem to find the answers to what I am looking for

It has 91k on the clock unfortunately the history is unknown, I intend to service it next weekend, currently it states service due in 4500 miles service A

I understand the recommended oil is 0w40 I have ordered TRIPLE QX Engine OilSynPlus Fully Syn 0w40 Engine Oil, as it has done 91k is 0w40 still suitable or should i consider using 5w50 or 5w40 or any other recommendations?

also i wish to change the gearbox oil it is a 6 speed gearbox, what oil do i need and how much, should i need to replace anything else seals, gaskets etc

Cheers
 
The 0W part of the oils designation is irrelevant to the engines mileage as it refers to the oils viscosity when cold. There isn't a huge difference anyway between 0W and 5W.

0W40 will be fine. I definitely wouldn't use 5W50 which would be too thick when hot.

The manual gearbox oil is a good question as they are relatively uncommon so there doesn't seem to be much information. As far as I can make out my 2009 C180k's 6 speed takes oil to MB spec 235.10. viscosity isn't specified but it's thin stuff something like 75W80. Don't know if yours will be the same. If you can find the gearbox type number there is an MB document that will point to the correct MB oil spec. I don't have access to that document at the moment being away from home but someone else may be able to point to it.

Mercedes-Benz Betriebsstoff-Vorschriften: Motoröl, Getriebeöl, ATF, Kühlmittel, Bremsflüssigkeiten



I managed to find the document I was thinking of but you'll still need to know the gearbox type number.

Cheers! as the history is unknown, what else should i consider replacing in addition to the basic service?

Also how do I reset the service? from what I've read you scroll to the page where it states the service info and hold down the reset button for 3 seconds, but nothing happens?
 
The gearbox oil isn't supposed to be a service item being filled for life but I agree it's a good idea to change it at that mileage. In the same vein of filled for life items the diff oil might be worth changing and the oil in the supercharger.

The spec for my diff is MB 235.7 and I was thinking of using Fuchs TITAN SINTOPOID FE 75W-85 It takes 1 L.

BTW my manual gearbox takes 1.2 L but again yours may be different.

There is a small amount of oil in supercharger to lubricate the gears. Again a non service item but some have changed it and you might be able to find a thread on it here.
 
any instructions in how to replace the manual gearbox transmission oil and the oil in the supercharger?

Cheers
 
Consider:

Engine oil and filter change (229.3 or 229.5)
Pollen/cabin filter change
Air filter change
Brake fluid change
Engine coolant change (unless long-life)
Spark plugs change

Also, not normally required but worth checking:

Gearbox oil
Diff oil
Power steering hydrauic fluid
Supercharger oil
 
And, if you have the M271 engine and no service history, then also timing chain and gear change - asap.

Hi Mark

Thanks for the info! appreciated!

How do I know if I have a M271 engine, it is a 53 plate c180 coupe SE Kompressor

(229.3 or 229.5) what is this in reference to? - I've purchased TRIPLE QX Engine OilSynPlus Fully Syn 0w40 Engine Oil is this suitable/recommended?

Any guides and specs for fluid to do the following

Gearbox oil
Diff oil
Supercharger oil

I'm comfortable with the rest...

Hi Ash & welcome to the forum.

The first 3 digits of the engine number denote which one you have and are shown on the V5 reg. document. The M271 is the only engine MB fitted with a single timing chain and can stretch and wear the camshaft sprocket gear teeth, leading to the chain jumping and causing damage to the engine. (Many threads on the subject here, just search for M271).

This link should help explain the various MB spec sheets, such as 229.3 & 229.5, again use the engine type for reference to them to determine which oils actually have the MB Approved requirement.

There are several oil company web sites which will give their recommendations and specs for there engine and gearbox oils, along with quantities. Google 'which xyz oil for my car'. xyz being the brand name, i.e. Castrol, Mobil, Shell, etc.

Hope this helps.

I'll get the first 3 digits and report back, cheers


I've purchased TRIPLE QX Engine OilSynPlus Fully Syn 0w40 Engine Oil via Eurocarparts, is this suitable?

Any ideas where i could obtain guides to do the following

Gearbox oil
Diff oil
Supercharger oil
 
Here's a link to the Castrol website, enter your reg number and follow the links to transmission fluid. (Click on 'All other recommendations' at the bottom).

Castrol

Final Drive / Diff Oil (Taken from Haynes Workshop Manual) Universal hypoid gear oil - SAE 85 W-90 or SAE 75 W-85.

Can't help with the Supercharger oil, sorry.

Hi Ash & welcome to the forum.

Also.... does you engine bay look like this?

Early M271:

Late M271:

Common M271 issues:

Timing gear and chain failure at 80-100k.

Split Vacuum hose under airbox causing power loss and EML light.

Leaking Camshaft Position Sensors (CPS) leading to oil travelling up the wiring loom and failed ECU.
 
Did MB acknowledge any of the M271 problems and make improvements or are these issues common to all production years to present ?
 
I service my wife's 2003 c180 komp coupe. I use 5w40 or 0w40 doesn't matter which depending what's on sale. As has been said not much difference and the first number is cold flow properties.

I've used Tripleqx plenty in both her and my w124 without any problems so far but then I follow an accelerated service regime at every 6k.

Just do a full service spark plugs air filter etc. Whilst your there.

Hi mark it looks like the 1st pic

The 'oil in loom' issue is addressed by fiting inline loom extention bits available from MB.

The split hose is not an issue as long as you are aware of it which saves a lengthy diagnostic process once the EML comes on.

The timing gear is a mystery because modified / strengthened parts are available, yet the original parts still suffer from the same issue well into the W204.
