Look what I found

W203E35

I did a little calculation and I'm not meeting Mercedes's standard on oil consumption (in other words I have a problem) of course I'm not (meeting it) if Erick is consuming .5 liters withing his whole oil change interval and I have consumed 3 quarts within 4,600 miles that should indicate something is wrong here.

By the way I checked my oil level today I definitely lost some.
Imagine below is the dipstick.

(min..........max)---------------------O

When I checked next day after I got back from dealer (/ - indicated oil level)
(min..........max)/--------------------O

Today when I checked in morning
(min......../..max)---------------------O

EDIT: I only drove 300 miles (and I'm not really pushing the car-seriously lol)

I have a feeling the dealer filled that bad boy up pretty good.

Keep in mind Mercedes states that 0.3 liters to 1,000 kilometers is fine anything over then there might be a problem.

1,000 km = 621.37 miles
0.3 liters = 0.317 quarts




Quart To Miles
0.32 = 621.37
0.63 = 1,242.74
0.95 = 1,864.11
1.27 = 2,485.48
1.59 = 3,106.86
1.90 = 3,728.23
2.22 = 4,349.60
2.54 = 4,970.97
2.85 = 5,592.34
3.17 = 6,213.71




I put 3 qts of oil within 4,600 miles

If your car really consumed that much oil in 4600 miles, then yeah, you really do have a problem.

samaritrey

you could you know accidently loosen the drain plug and let out a quart. of course accidently and accidently forget to tell them. lol

Wow - They are prepared to do a warranty engine replacement for this. Good sleuthing man, I bet they would prefer to keep this one quiet. Interesting valve guide seal comment. The last time they had a run-in problem with MOS2 coated rings they brought out reprofiled rings. I thought this problem was history - Keep at them & make sure they understand you know about this bulletin. That's why they dont want to do a leakdown test - It would show this immediately.

Glyn M Ruck

Or just suck a little out - Karo's car genuinely uses oil though - don't think he will have any problem proving this.

W203E35

Thanks guys, I'm not worried i'll have them take care of it. I'll even mention that I know insider secrets about the M272 engine and how it burns oil
I'll make them do a leakdown test
I checked today when I got back home 50 miles to go. Sounds like I gotta call them Monday and take it in Tuesday or Wednesday. I'll keep you guys updated.

W203E35

So I got an appointment for Thursday. I found how they do a test of oil consumption. I believe this is what they did to me. I think they are really going to be surprised when they see what happened.

So if they give me the run around the best thing to say is "Do an Oil Leakdown test" right?

Glyn, you are pretty positive I have a problem right? I mean I searched other cars and they did not have a section for oil consumption and being ready to change an engine hahaha

I'll keep you guys updated.

For the record I did not pump or drain any oil out. From the original dipstick to now oil has been burn so I am very confident. I just hope they don't BS me and say everything is fine and say it's the way you drive. Eighter way I'm going to be very aggressive.

How many people have had a replaced engine? Is the removal and installation of a new engine an easy job? Is it a job that can be done competently by a mechanic at a dealership?

This is the problem with dealerships, there is no quality control check. The mechanic does his job (either does it well or does it with a flaw or two) and gives the customer back the car. In the factory, there's a quality control check.

Thus, I'm afraid that if they replace the engine, will it be done perfectly. I don't think it's a common job, so I'm currently concerned if they'll do it perfectly.

This is the United States, this isn't Japan. Sometimes the work ethic isn't perfect, if you know what I mean. Often-times, even mundane tasks need to be done twice since the mechanic was lazy the first time and tried to cut corners.

W203E35

I agree with you, I am kind of nervous for issues in the future but something has to be done with the engine. If I was loosing 1 qt every interval I can live with that but 3 in 4,600 that 7-8 qts withing the service interval. If I do need to have an engine job I just hope the techs know what they are doing especially since warranty is going to be over in Mid November. I had to take my transmission in 3 times before they finally took care of it so I know what you mean.

patrick_y

If they replace the engine, the dealer should give you a one year warranty for the work performed (a parts and labor warranty). This warranty should hold even if the rest of the car itself goes out of warranty.

The problem of this is that it's the dealer's word against yours. Say they replaced the engine and six months later you're having problems. You take it to the dealer and you ask them to fix it. They may tell you that it's not the engine (when in reality it is engine related) and they'll say that this is not related to their part or labor. If this is the case, your case will be difficult to argue.

Glyn M Ruck

Hi Karo - just a Leakdown Test - not "oil" leakdown test. The test is done with compressed air.

Yes - unfortunately your consumption is too high & they must fix it.

Don't worry if they have to change the engine. They have to give you a warranty & the engine will come as a sub assembly & heads. All they have to do is mount all the add on's & connect up. It's a big job but you can always get MBUSA on sides.

Glyn, Erick (e1000) mentioned to me last night that a couple of the SLK350 guys had their engine replaced due to oil consumption. I checked my cars build date 07/05.

Do you happen to know if this is considered an early build date for an 06?
What month do they usually start building the new model?

Thanks,

Karo

Glyn M Ruck

Karo - sounds a bit early but 2010 spec 204 are being delivered for US already so for the North American cycle July might not be early.

Thanks for the info Erick. This is another secret weapon I have.

I'm ready for tomorrow. I know they might BS me but I am ready.

Thanks for all your help guys. I really really appreciate it.

I'll keep you guys updated.

Update:

So I took it in today morning. My SA calls a tech over (I drove 700 miles) and all he does is takes the dipstick out and says it's fine. The **** says nope you are not burning oil. I said that's impossible and he says ok drive it 200 miles more and come see me.

This is when I get pissed. I say "Are you serious? You guys said it's fine and I drove 700 miles and now you say bring it back 200 miles?" he says we can't do anything and I say ok do a leakdown test. He says that this is not a procedure that they do (now I am really pissed) I say "ok so I bring it back and nothing happens what do I do next?" he says we'll wait till the light comes on. I told him ok document it. He said come back in 200 miles and we will talk about it.
By this time I am ready to punch the guy in the face. and at one moment I did make a fist (lool)

Then I say "You know what this is bull shyt because you guys never documented any oil and you had to weigh and document the info and send it in to Mercedes Benz to get an approval to change the engine" he says well you are still under the limit.

I give him a look and say "what the f*ck is the limit? he says 1 qt for every 600 miles. By this time another tech had come by and I asked him "You...what is the real limit. He says 1 qt for every 1000 miles. I say both of you *** holes are lying to me I looked it up it's .3 L for eevry 1000 km that means .32 qts for every 621 miles. They say that is not true and I told him how people don't even put 2 qts in the whole 13,000 interval.

Then my SA says we'll come back in 200 miles (this was the icing on the cake) I say "GO F*CK YOURSELF ****" (sorry I just couldn't take it) and left.

Then I called MBUSA and filed a claim and told them everything. I told them how nothing was documented and told them exactly what happened and said it seems like they are prolonging the work so my warranty finishes. The guy was nice he did not once try to back up the dealer. I felt like he was on my side.

I even told him how I have documented proof that I took because I lost 3 qts at 4,600 miles and that they said nothing found and atleast they should have started the oil consumption test because I am over what is considered ok.

So he filed a claim and took down dealer info and said they will call me within an hour.

This is just proof that the dealers are really crooks.

I want to thank all of you for contributing to my problem. Without you guys I would have been blind to see that yes there really is a problem.

Cmon obviously there is a problem. Erick has same car and adds 1 qt for 13,000 interval and I already added 3 qt within 4,600.

There is definetly something wrong here.

I will keep you guys updated. Once again thanks so much guys I would have been in a much worse situation couple of years/months down the line when I need an engine job and I don't have warranty.

samaritrey

I know exactly how you feel some dealers just don't care that is why i changed dealers so many times. the sad thing is some of the techs don't really know anything and with 99% of the customers won't argue with them. you sound just like me when they cracked my bumper and said something about how it was a stress crack that forms over time. i have also called Mercedes directly and they car very helpful they are the ones that actually got my car fixed after the incident. then about a week later the general manager sent me an apology letter for the whole incident and for trying to get out of fixing something one of their employees did. hope that this all turns out ok and you can get your engine fixed properly. for the record i would not take your car back to that dealer even if they say they will fix it because it only takes one employee with a grudge to ruin your car.

W203E35

This lady called from MBUSA and she was being a real jerk. Basically putting words in my mouth. I told her everything and she said she didn't hear about weighing the oil. Then I said I have the paper in front of me and I can email it to you. She said that she is not a tech and I said let a tech see it she said where is it on the Mercedes website I said it's not. She said that it's not valid as long as it's not from the site. I said this is the info your techs use. She said how do you know that I said I just do, it doesn't matter what I know and what I dont know and how I found out. Bottom line is your tech didn't document anything.

Anyway she said she will call me in a day or so. She has to call the dealer and get it straightened out.

I'm thinking of actually having someone do a leakdown test and when they BS me I can prove to them.

Glyn, is the bottom image a leakdown test?

Glyn M Ruck

Karo - Take no crap from MBUSA - Insist on talking to their most senior technical man who should be the National Service Manager or Director. Don't talk to junior idiots with no say or decision making capability - You have every right to quote MB TSBs & methods.

Yes - that is the Merc method for leakdown testing. I'm surprised they don't use a more sophisticated rig but that will do.

W203E35

There is also this: Don't know what this will be used for.

Glyn M Ruck

Thats a boroscope for examining the inside of the engine for cylinder bore scoring, damaged valves etc. The term endoscope is usually only used for the medical versions of such devices. That box is the light source for the flexible scope.

W203E35

Glyn, one last question I know I am bombarding you with pictures and questions but why do you think they just don't do a Leakdown Test? Why do they have to go through the trouble of adding oil and weighing it and checking?

Is this because they know the Leakdown Test will show more than just the customer driving?

Thanks

lazines, lack of quality service, carelessness, cost cutting, cost cutting and cost cutting.

W203E35

You are 100% right Eric. I read a lot of places that people are paying out of their own pockets to do an Leakdown test and then shoving it up Mercedes's ***. I'm gonna go have this done at a private shop and have my car taken care of.

It's funny because a lot of people even with same model cars have oil consumption problems and some have very few and most don't at all.

I'm starting to think this was the Engine Break In that messed everything up.
