K40 Relay....which one is it? (Pics)

[BenzOnline]

I need to access my K40 relay on my 99 C230K W202 for a possible burnt solder joint and I opened the box but not sure which one it is. There is a orange relay/fuse looking thing with "40" on it but not sure if thats really it.

Here are some pics...maybe someone can circle the K40.

That car like most from 1998-2001 has 2 K-40 relay "GROUPS"

There is K40/4 in the passenger side computer box!

There is also a K40/2 in the drivers side fuse/computer box.

WHAT type of problem is the car having?

The car is having an issue with the boost when accelerating. IT is not very strong anymore and the kompressor is indeed engaging...aswell it doesnt run with cold starts anymore like its supposed to (making that tractor sound at cold idle) instead its smooth and quiet.

It gets its full boost when accelerating from a stop to redline but going on the highway and kicking it down...nothing...normal aspiration.
