[Check Codes]

I have the same M112 in my W210 and the EPC shows only one CPS for it.

OP, I've never heard of your ebay seller, but I'm always suspicious of ebay deals that are too good to be true. There are lots of Chinese replicas out there. Autohausaz.com will ship outside the US for a fair price and they have it -- genuine Bosch -- for $60.

Take care and enjoy the ride,
Greg

Hi, Julie, my welcome, too.

Just a couple of suggestions since it sounds as though you and pops (with Keyhole's help) have the present situation in hand.

First, when a mod comes along s/he can cut you posts out of this thread and create a new thread in the 208 forum, so while it would have better on it's own that's not a crime. So, until that happens you might as well continue here.

Second, most of the members on here are from the US, and on this side of the pond we don't get that engine in the CLK. So when you're searching for information related to your engine -- as opposed to your 208 chassis -- then check in the 202 and 203 forums as those are very common engines in those chassis.

Last, the MAF is the assembly you describe, but to properly clean it you need to remove the sensor insert (the nodule) and clean the port in it. The assembly is quite similar to the 210 design, and I did a pictorial DIY in that forum on how to clean it, it is in the help/diy stickies, engine section.

Take care and enjoy the ride,
Greg
