Need some help! Panoramic sunroof and more!
Hello everyone,
I had few question and trying to see if someone can help me. I starting to get creaking from the sunroof. I had it lubricated from the dealer about 8k miles ago. Really trying to see if anyone know how to DIY it. I really want to do it myself if someone has any advice what to lube and how. Also I feel like my headliner I making a noise.
2nd question is mpg. I not getting good mpg 2015 C300 4matic. I had the wrist pin issue done from dealer. And I barely get about 21mpg in city and 24-27 on highway that when you really baby it. I use shell 91. Don’t know why. If anyone have any advice. I do have 19 inch wheels with 245/35/19 all around.
3rd question is: I’m about to do a trassmission fluid change I have 56k miles on my car. Just wanted to see if anyone know how much fluid the car takes. I heard 4-5 liters but double checking.
Thanks everyone

Sunrooof: there's literally a huge thread dedicated to this on the front page of this subforum
2: this is normal MPG
3: transmission flush not required or recommended until 100k check your manual for more information on your specific model
additionally: you need to make sure your plugs got done @50k , if not go ahead and do them

Ya
Changed plugs 40k with original parts.
transmission fluid I don’t trust the myth about lifetime fluid or don’t need until 100k
I always changed after 40k a lot people do that.
