    Hi All,

    I own a C220 CDI W204 (2011) Blue Efficiency and I have a Service Care Plan for 3 years, this would include BAB service.

    My service was due today (B service), and so this morning I checked the EES Guide and it said an ATF was due. It has not had one done previously. The mileage on the car is 42100. The car has always been serviced by Mercedes, and I have all the DSS print outs.

    I took my car to Coventry Dealership and they have said I don't need it, and they showed me their ESS Guide which has the part where the ATF is due, crossed out. They have said the sheet they have is correct and not sure why, when I showed mine, that it had it on there. They were adamant the change is not required.

    I am now confused, is my car due for an ATF change? I thought the ESS guide online is accurate!!

    Any help would be really appreciated.

    Thank you
    Mo

    And I wouldn't get the ATF changed by a main dealer for a 6 year old car.. take it to a good indie when you reach 70k miles, you will save 50%

    Thanks Kam, I thought ATF would need to be changed according to the ESS Guide.

    Will look for a Indie in Coventry, although not sure if there are any!

    Check your manual, on some w204 it is due at three years or 31k miles as a one off change.

    Had the same discussion with MB Ashford when I bought my S204 C220. I believe that cars like mine, with the 5 speed autobox, MB claim it is sealed for life and the ATF never needs changing (which is a load of cobblers) whereas later cars with the 7 speed autobox have an ATF change at 37k miles and then are "sealed for life".

    Another story I've been told by my local indie is that originally the "sealed for life" meant 150k miles for ATF change, most cars were away from the main dealer network by then, there were quite a few autobox failures damaging MB's reputation for reliability - so they started the change at 37k miles when they figured most cars would still be in the main dealer network.

    I have yet to change the ATF on my S204, but with 80k already I'll get it done in the next 12 months (indie B3 service in Jan this year, said to leave it until next service). Had it done on the S203 at about 70k (gearbox seemed fine before) and it did make the box smoother.

    My S204 had done 37,000 when I bought it.
    I carried out what I call a 'base line' check so that I know where I am with this car.
    The check is basically change all fluids and filters, carried out by a competent, honest, mechanic.
    My ATF change was the biggest item on the list, and he advised me that the drained oil was pretty brown and was due for changing.(Its to do with the modern non Asbestos friction plates fitted these days.)

    The OP has a Service Care Plan, do the ATF change at the dealer would be free, but only if ESS says so....

    I think the issue is that the online ESS simply asks for the model of your car, while the dealer's ESS is (presumably) linked to your car's VIN hence more accurate.

    Thanks Chris and Tony.

    I have the 5 speed autobox as well, and I am sure I have read on the forum that the ATF should be changed.

    Unfortunately I don't have the expertise to do it myself, wish I did though!

    I still have a care plan with them so I will wait and see what happens at the next 2 services.

    Thanks Mark, that is what they said to me. As they check their system with my VIN it prints of what is required, as such the ATF came out not required. (With a line through it).

    I don't let incompetents tell me what and when maintenance is due, they are mostly computer driven, especially at the main dealers.
    On my previous BMW, the car's computer told me that engine oil needed changing at 15,000 miles.
    You must be joking! I changed the oil at 5,000 miles, and the engine was as sweet as a nut when the car was dragged off for scrap.

    I think we all agree that it is a good idea to change the ATF...

    The issue here is that the OP has a Service Care Plan, which means that the MB dealer will carry out at not extra charge whatever the computer says needs to be done.

    Of course the ATF can be changed at the dealer or at a specialist for a fee, but the OP possibly feels shortchanged by MB on this issue.

    Lots of discussion about 'sealed for life' gearboxes, but even the least mechanically minded must realise that anything with metal moving parts in it that are rubbing together will wear, and the fluid covering them must also suffer some degradation.

    Get it changed. Cheap insurance, if done correctly. Had my ATF , diff fluid and brake fluid replaced recently, just for piece of mind.

    Again, this is the issue here, not simply if it's a good idea to change the ATF or not....

    It would be interesting to see what the Service Booklet says for the OP's car, and if the Servicd Booklet does say that an ATF change is needed, then try and confront the dealer on this issue..

    Although its may be specified in your handbook, the owner can interject at any time.. I have a Jeep with the Merc Engine and box (5 Speed Auto) and I get the fluid changed every year - at £156 for an autobox service it really is a no brainer.. and you can feel the difference on change, the shifts are smoother. When I got my Merc C it was the first thing I did for piece of mind.. even although I had a reciept saying that it had just been done a few months back.. when I saw the fluid and filter, I'd say at least a year + as it was manky.. so really if you feel it needs done do it! A Jeep recon box is £3k hence you see a lot of them on Ebay "Gearbox fault - cheap fix" Only if you have a large wallet.... so be warned...
