Engine Oil Warning Message
I have a "check engine oil at next fueling message". I'm at about 5K miles and I understand it's pretty common for diesels to burn oil when breaking in, so I'm just going to add a bit more.
Does anyone know if the warning message will automatically be cancelled when I add oil, or does it need to be reset by the dealer?

BTW, in 30K miles, I have never had to add a single drop of oil to my car. I did have the faulty sensor, though, and that required a few days to repair.

If the warning is really due to low oil, it should reset itself. However MB had a problem a while back with faulty crankshaft sensors giving low oil warnings. That resulted in a recall. I suspect your problem is not that sensor because your car is so new, but if the oil light doesn't go out after you add then you should consult the dealer.

We have had the same warning come on about 6 times in 3K miles since new. It seems to happen whenever the fuel guage is close to the 1/4 mark so I thought it was just a planned warning to check the oil early in the life of the engine.
We are going to have the hitch receiver recall done this Friday so I'll have them look at this issue also, as well as the 'SRS' warning light that came on and stayed on this weekend; (but is now off).

I had the check oil light problem in my 08 GL 320. I added 2 quarts in 6500 kms, the oil was at the full mark and I was still getting the check oil light at next fueling. It would go away after a while.
I guess I had a defective sensor I believe.
I added Mobil 1 5w30 syntetic and the dealer said it was fine.

Get the name of the person at the dealer who said that "5w30 was fine". Then, you can TRY to use that incorrect info in your fight for your upcoming Diesel Particulate Filter failure claim.
As for the level, when I have my oil changed, I insist and check that the dealer fills the oil to the full mark on the dipstick. In 31k miles, never had to add a drop.

I don't have my manual to check, but my salesperson said there was no way to check the oil, not even electronically like my Porsche. I would only know there was a problem if the oil was 1 qt low.
???
Oh, and that is the oil for the 550 as well? I was briefly looking at the manual yesterday and it was referring to some inserts that I didn't get a chance to find.

"MB Sheet Number (vehicles with a diesel particle filter) 228.51/229.31/229.51"
-and-
"In the event that the:
engine oil brand
grade (MB Sheet number)
SAE classification (viscosity)
is not available, you can use another mineral or synthetic engine oil which has been approved by Mercedes-Benz.
Mixing oils reduces the benefits of high-grade engine oil."
So, it looks like they are only going hard-core on 229.51 in America, and it seems to have more to do with service interval, than particulate filter failure, even though that's what they say...

For those who are getting oil level warning but your oil level is correct, check with dealer to make sure you have newer mounting bracket for oil level sensor. Some of the brackets had faulty design and the sensor would not be mounted deep enough to read oil level at all conditions.

The oil referenced earlier in this thread is specifically for MB diesel engines. You can find the 550 oil specs in the approved products pamphlet that came with your owner's manual.

This is hilarious to me: I had the manager of a dealer who has been selling MB for 30 years tell me there was "no way" of me checking the oil level! I figured he oughta know. Now about everything else he told me..........

Few things:
1.) I had my sensor replaced, my tech is actually a personal friend and said there was a TSB on it.
2.) My dealer gave me 3 quarts of the 229.51 oil... roughly $7/quart.
3.) I love my diesel GL...

I've had the message come up twice. one time the dealer said that it was a tad bit low and the other time they couldn't confirm that the message appeared. They told me not to worry about it; it may be a glitch.
Glitches happen once, maybe twice. If it happens again, I am taking it back

Dealer Just Filled It To MAX
My wife just brought our GL in for the trailer hitch recall. We told the dealer that we have had a problem with getting the check oil message even when the dipstick had the oil level right in the middle of Min/Max lines. I would add a half quart of oil, barely changes the dipstick level and the message would go away, but it would come back a few weks later. Still with the dipstick level right in the middle of Min/Max lines. I do not have any oil leaks under the truck.
The dealer did not refer to any service bulletins for our truck and did not change any sensors. Just noted on the worksheet "topped off oil." Our truck is a 2008 which was built just before we took delivery in November 2007. I checked the dipstick when I got home from work and the oil was just filled up to the Max line. I guess that was their fix?
I don't know, I am going to call him tommorrow. Seems to me you shouldn't get the warning message if the oil level is in the middle of the Min/Max lines on the dipstick.
Other note that I posted before in another thread is an on-line source for the oil that is recommended. You have to buy it in a case of 6.

I've had the check oil warning come on a few times now, mostly after driving a while at highway speed, and the oil level is exactly where it should be. The dealer says per TSB on oil sensor they're replacing, but it's going to take a couple of days (apparently it's an involved job to get at the sensor). It always makes me nervous when things have to be disassembled and re-assembled at the dealer, though.
Those of you who had oil sensors replaced: how long did it take and did it resolve the issue? Did you get any sense as to what was involved? Thanks.

Dropped it off in the morning; picked it up a few hours later. Problem resolved completely re: incorrect oil level warning light coming on. Was never told it was an 'involved' job. I wouldn't worry about it if I were you; everything should go fine.

I'm getting the check warning too while at highway speed. Although it would reset itself but come back on later.
When is the "right" time to check the oil level, wait approx 5 mins after the engine has been running or longer?
It seems if I check right after, the level would be at mid-point but if I wait say one hour or so then it would be much higher.

Get the engine to operating temp, then turn it off and check the oil level in about 15-20 minutes. If it's fine, its the sensor issue.

Had same problem here, also after (or during) highway driving. The dealer flashed new software. When I asked about a new sensor, the SA said that the new software fixes the problem 90% of the time. So far so good after several weeks. If you are nervous about surgery on the engine, you might try the software flash and see if that takes care of the problem.
