I had the oil changed at the Aston Martin dealership when I bought my car. They did not follow Mercedes procedures and drained it out of the pan. I have had a very slow drip out of the oil drain plugs since I bought it. I took it to Mercedes today and specifically told them to add crush washers to the (2) drain plugs. When the car was returned to me, they noted that the (1) drain plug had a new crush washer. I went round for round with the service dept that there were 2 but, the tech had left and nobody was around to put it on the lift. I climbed back under the car tonight and confirmed there are 2. I'm wanting to get someone to confirm this before I raise hell on Monday. There is one on the drivers side of the oil pan in the front and a 2nd on the very rear of the oil pan just before the transmission. Someone please confirm I'm not crazy.

Thanks,
Todd

2 drains

Thank you....

I'll be going to Mercedes of Memphis on Monday to raise hell and get that 2nd crush washer installed. Absolutely mortifies me that the Mercedes tech would argue with me that the 2nd plug I saw was for the transmission...

Thanks for confirming what I was 99.9% sure about.

I have both an E63 and C63, both cars have the same M156 engine. My E63 has two drain plugs as well, but my C63 only has one. AMG obviously used a different oil pan on the C63, probably due to the different engine bay configuration. How do I know this, I changed my friends oil on her 08 C63. Now my 2010 C63, I have had a oil change on it yet, but I assuming that its no different.

Todd it is not the washer, it is the plugs, they are micro encpasulated and can only be used once.

+1. 2 pans......2 Plugs

The plugs come with some kind of thread lock on them and are one time use. They are pretty cheap so they shouldn't make a bid deal out of replacing them. I just bought a bunch last time I needed some so I wouldn't have to keep finding the part numbers. The plugs were $2.78 and the washers were $0.75 each.

Here is a picture of what the new ones look like.

make sure they pull both plugs and drain all the oil again.
they should redo the entire oil change. hopefully its an open shop so you can watch the tech do it.
im suprised they didnt extract the oil

I recently had a somewhat similar encounter at my dealership when ordering the plugs. Parts guy insisted there was only one on my car (06 E55) based on whatever their database was showing. Turned out they somehow had the wrong engine listed for my car since when i reached over to look at his screen the engine looked totally different (maybe a 63) so you might want to check that with them as well.

I had this problem at a local shop. They only pulled the front plug, then filled it up with oil. My oil sensor light blew because of this and I had them redu the oil again. I should have had them replace the sensor but didn't want them messing with my car anymore.

Todd Edge

Where did you get the plugs for this price?

Thanks,
Todd

it just a mistake.. why you raising hell?

Richard55

I got them from getmercedesparts.com. I think it is the Annapolis MD dealership. I didn't shop around that much so I'm not sure if they are cheaper other places or not.

The absolute only reason I got the oil change was to get the plug leaks fixed. I didn't need an oil change for another 8000 miles. I specifically told the service advisor to check both plugs. When I got the bill, it showed only 1 new washer and the tech raced out while I was dealing with the service advisor. They got the tech on his mobile phone and he swore up and down that an E55 has only (1) drain plug and I didn't know what I was talking about. I specifically told them about both plugs and they appear to have had a tech with no clue. In addition, he spilled oil all over the supercharger, expansion tanks, and it dripped all over the exhaust. Just seems like they had someone with no clue. I'm simply going to request they redo it and add new drain plugs this time...

So is extraction the wrong way to change the oil?

They only have to drain from both plugs if the car is on an uneven surface correct? If you are on a even service and they are draining it from the front plug that should get it all out right? Thx.

Todd Edge

I'm new to Mercedes but, from what I can gather from this thread and a few others I found, either option works. The dealer seems to only do extractions. Others that do their own changes state you must install new drain plugs and washers to ensure no leaks. My issue started when I bought the car from a non-Mercedes dealer who drained from both plugs and reused the plugs and old washers. Once I correct the issue(new plugs and washers), I should be good to go.

I had my oil changed just within the last week and they reused the washer and plug, but after reading this thread I am not sure if they did it correctly. I know they did it from underneath the car because they have an underground pit, but only from the front plug. I am worried because a couple of people in this thread have posted that there is two plugs and pans. Am I okay if he drained the oil from the front plug only on a flat surface? I want to make sure I am not driving around with old oil still and too much to the point where the engine blows up. Thanks.

When I change mine at home I get most of the oil out of the rear sump. The front lets maybe another quart out, but I haven't measured to get an exact number. Do you know how much they put in after the change? You can use that to figure out how much they didn't drain. It takes close to 9 quarts to fill up the E55 if you drain both.

Yacht Master

Guys, did anyone read the "Star bulletin" Mercedes Document I posted?
It is clear on the plug and washer issue and that the E55 has 2 sumps that can not be vacuum extracted. The E55 is the only MB that can't be extracted, and most dealers have no idea. How do I know this? Lets say a dealer gave me 3 free oil changes because they thought it was the washers and kept replacing them, but the leak kept coming back.
Here for those that missed it the first time.

Todd Edge

I spoke to the Service Manager and referenced this exact bulletin. After a few minutes, they agreed to pick up my car, do a new oil change with 2 new plugs and washers, and return the car to me. I think the tech that did the change simply didn't know what he was doing. All seems to be resolved.

One quick question. They put Mobil 1 5W40 in the car. I thought it needed 0W40 Mobil 1? Was this another oversight or is this alright?

Thanks again for all of the responses everyone.

Thanks,
Todd

So are there 2 separate oil pans holding oil or is there one pan with 2 plugs that can be emptied by either plug? I need an answer asap please, thx

nanayaw6

Single oil pan with 2 drain plugs one facing the rear (on the driver's side) and the other facing the driver front wheel (have to take front underbody cover to see this one since it is somewhat blocked by the front sway bar).
Drain the main (rear) one first, then the front one and don't forget to remove the oil filter as that will let some more oil out. Just did all this last night.

PS: The design for the pan is hard to explain but once you're down there, it will make sense why you get close to an additional quart out from the front drain. Hope this helps

mikey33

Your correct. As much as I love this forum it always seems there are people who don't know what they are talking about. Mercedes confirmed one pan and two plugs.
