Does anyone have a video showing me how to replace my mass air flow sensor (MAF) on my 02 kompressor? Maybe a youtube video or a reference document with diagrams? I already searched via google and youtube for a video, but no luck.:surrender:

It's about as easy as it gets - remove the air filter housing and the MAF sensor is right there on the side, where the air intake tub connects. There are a few bolts holding the air filter housing in place, then a few bolts attaching the air intake tube to the MAF sensor.

thanks for the info. I feel better knowing that it's pretty simple. But since this is the first time doing this, I want to be certain that I will be doing the work correctly, thus the request for a diagram, etc.

Thanks for providing the info, but the R&R of the air filter housing looks like a lot of work and not that easy. I thought the air filter housing was where the air filter sits? no? My air filter is in the front is in a rectangular housing. Is there a way to install the MAF without removing the air filter housing?

Oh, you must have a "MY2002" with the M111 engine instead of the M271. In that case, it's just behind the air cleaner. The replacement is almost the same, but removing the M111 air filter housing is a bit easier.

I don't know for sure, but that eBay listing sounds like WIS. For $12 it, might be worth taking a look. If it is WIS, I will warn you - installation is not always very easy, and since it's hacked, the instructions may not be entirely clear.

I replaced my fouled maf a few weeks ago and it was easy. The tools that help most are locking pliers and a snake driver. The locking pliers will hold the metal clamp open on the throttle body side and the snake driver will allow you to easily access the two torx head screws holding the maf. Should take about 10 minutes, max. Dont forget your plug on the side.

Locking pliers have the ability to clamp and lock closed. They have an adjustment on the end for jaw width and an additional lever to release the lock. A snake driver is a racheting screwdriver with a flexible shaft that allows you to get into difficult to reach areas.

That's my diagram. There is only one MAF sensor - part #8. There are two part number in two different intake configurations. One setup is for option code 918, which is "unregulated emissions control", and that's not valid for US or Europe. After looking at this diagram. I realized I selected the wrong car - that's a W202. So then I went looking for it on the W203, and I can't find the part number - it refers to a chassis number issue, and that means you'll need someone with the online version of EPC to find the right one.

Started working on replacing my MAF, but had to stop because I could not remove the interior torque screw - not enough space to put my socket wrench. So, now I will go purchase a snake driver, and resume. On a side note, the MAF I ordered online is OEM, but it says that it's made in china. Should I be worried. I'm a bit nervous about the quality of parts from china.

An OEM MAF sensor should not be made in China - it should be Bosch from Germany. Where di you buy it?
