Question about MB-Tex
The first time I noticed it was right after a dealer visit, so I thought it was something they had sprayed on the interior. Now, two months later, it just came back.
Has anyone heard of this before? If it's not a known issue, I'll go back to my original assumption that the dealer sprayed something in the car. Why it's recurred after all this time is somewhat of a mystery though.
I'll call my dealer Monday and ask if they do, in fact, spray the interior with some leather treatment. If that's the case, why would the sides of the headrests also show this oily seepage? I am really puzzled by this.


It hasn't come back for me, but it's only been a couple of days.

gnus's comment, "I had this exact issue, and noticed it while I was at the dealer; it's a known issue where the factory is supposed to wipe down the seats with a special solvent before they leave the factory. Apparently, that wasn't always done, so they instructed the dealerships to do so before delivery. Apparently, that also wasn't always done.," may be the root of this.
Monday, I'll give MB-USA a call and then follow up with my dealer. I'm guessing it will resolve itself anyway after a few cleanings, so I may just take some pictures to document it, then wait and see if it comes back again.
I really do like my C300, it's a truly exceptional AWD sedan, but it is feeling more and more like I bought a kit car that I have to finish myself. This is my first Mercedes, and certainly compared to my experiences with BMW, Audi, and Porsche, I am somewhat disappointed with both the factory QC and the dealer support I've gotten so far.

W204 gave some trouble with MBTex delaminating & cracking. Maybe they've decided to give it an increased dose of volatiles or maybe it is a local supplier.




These pictures were just emailed to my salesman with a mention of just how disgusted I am with this. I'm sure I'll hear back tomorrow.
Now, I am getting really upset. I did spend an hour scrubbing the front seat with warm water and a mild detergent. Most of it came off, but you could still see the outline of the stains.

Complaint
Oily, shiny surface or white residues on MB-Tex seat covers
Cause
- In cold weather the surface of the MB-Tex can appear oily or shiny (IMG_2055.jpg, IMG_2058.jpg)
- When the material warms up again, the substance evaporates and this can result in white edges on the surface (IMG_2054.jpg)
1) For customer vehicles with issue only!
Replace the seat cover and head rests, except for the front passenger seat bottom.
The passenger seat bottom cannot be changed at this time because the factory calibration is performed on the cushion/cover/bladder as a complete set.
We are currently in developing a spare part kit, once established, this Tips LI will be updated.
2) For vehicles in dealer inventory
Please clean the seats with warm soapy water solution (do not use aggressive cleaning agents) before releasing to customer.
A final resolution is currently under development, this LI will be updated accordingly.

I will forward this to my dealer. I assume they'll have my car for several days to take care of this
Thank you very much!
no problem. and yes pay close attention to the final quality of the new installations.
I can understand your frustration - outrage?- and I'd be equally pissy at the thought of having the seat covers replaced on a new car.
I'm trying to bite my tongue and let me know if I'm out of line but...wtf is wrong with this new C-Class???? Is this another Alabama QC or supplier issue or is it global (I can't interpret the origin of the tech bulletin)? I see that the MB bulletin suggests that inventoried cars get a wash with warm, soapy water before delivery. I'm confused because I assume you've done this multiple times already?? If so, and considering your pics are worth a thousand words, will other new owners experience the same problem and the same "don't worry, we'll replace your seat covers" solution?
All I can say is "Wow". And I sympathize of course. Looking forward to hearing about your resolution.
