1. I need to replace MAF sensor on my 2003 c230.
Where is the best place to order MAF?
Does it take only 2 torque screw to remove and replace the MAF?[&:]

2. The sunroof on the same vehicle is opening only partially - app. 1 inch at a time when I push the sunroof button.
This happened a few month ago but was working properly for another few month before this happened.
What is the exact problem?
Do I need to replace the motor for the sunroof or the whole sunroof?[X(]

I would appreciate much if anyone can answer any of the above questions.

 

Oder the MAF from a reputable parts store, stay away from EBAy. Dealership is the safest bet if you can afford it.

You may need to re-synch your sunroof. It's in your manual how todo it.

 

One thing it could be (and sometimes the simple answer is best): the rails may need to be regreased. I use my sunroof in my '06 C230 a lot and sometimes it will only close 1/2 way when I hit the switch. Each time I take the car to the dealer we make sure the rails are well lubed and it solves the problem immediately.

Take it for what it is....it could be more than that but its worth a look.
