C220 CDI W204 722 Auto Box Oil Change Problems DIY
Hi friends,
C220 CDI W204 646.811 engine, 722 box July 2007. My auto oil has not been changed at the recommended 60k nor the 120k mark (no diesel fuel filter change either!) and, of course, I did not look at the service manual too closely when I bought the car privately and naively thought the name Mercedes guarantees excellent service here in Perth (Oz). There is a lot of info on the web for DIY and I would like to hear yours:
To do a proper oil change it would need a proper flush with 15 litres of Merc oil, which my non-Merc mechanic cannot do as they do not have the fitting on their flush machine to attach it to Mercs. Besides, he would not use the Merc oil as it is too expensive. DIY means oil is left in the torque converter plus if you do not let it drip for a long time an extra 1.5 litres will stay in the box according to one DIY man. Suggestion is to crank it at 200 RPM (NO STARTING!) to get the oil out of the torque converter?? I may not be game enough to try that. Looks like us DIY boys are at a disadvantage to do a proper job. I wonder if Merc is doing a flush and how much that is going to cost!
My mechanic is rather hesitant to do the job and has already fobbed me off twice as he cannot see him doing a good job without a flush. He is suggesting a two-hour job, which means he would leave 1.5 litres of oil behind as it is not allowed to drip. All I can think of is suggesting to him coming in late PM and letting it at least drip overnight or doing it myself, but I am not too happy as I feel sick (nauseous) working under a car, but I will manage.
I am a pensioner, who hopes to get another 100,000km out of this badly serviced Merc (120k on the clock), but I suspect it has to be serviced properly to get those extra 100K out of my last car, hope, hope.
Your thoughts, please!
Regards

Hello and welcome to the forum! Other members may chime in as well; but it sounds like the car just needs to be taken to a proper mechanic who has experience working on MBs. I'm not sure I understand why the mechanic is hesitant to use MB oil, what if you provided it yourself? You're absolutely correct in thinking that to get another 100k, you're going to have to service it properly. I'm attaching a link to our site's DIY tech articles on the W204 platform. There are a lot of step-by-step guides, including oil changes, that you should find helpful if you're going to be working on the car yourself or can be given to your mechanic as well. Please let us know if you have any other questions or if we can assist with any part needs in the future - we're able to ship worldwide.
