So,what should I do for testina turbo pressure?

Or it's dire It Will Be the intercooler and can directly order a new One?

If you don't have oil drips splashing on the rear panel when driving, the hole in the intercooler is not large enough to affect the boost level.  This is my experience with two different cdis, both of which had holes in the intercooler, splashes on the rear panel at the end and both were still boosting to almost 1.2 bar even in that condition.

I think the problem is that,because I have oil dropes on the Left side

OK well maybe the hole in your intercooler is larger than mine was. It needs to be changed - whether this is the cause of the bad performance or not.

I think you can inspect condition of intercooler from below the car looking up. Its scoop may have to come off.  I’ll check on mine in the morning.

As regards using diagnostics to read boost pressure, I believe only MB Star and WinStar can read live data boost pressure on older 450 Cdi Smart cars. The easiest option is therefore reading boost pressure with a pressure gauge. You can T into either hose from inlet manifold to inlet manifold pressure sensor or hose from turbo compressor to waste gate actuator. You need a long enough hose so you can read gauge safely from driver’s seat or bring an assistant.

These are some photos from below.

I think in the photo of the intercooler there is some space under it like a damaged one,tolsen can you see it?

It certainly looks like the oil is coming from the cooler location, but the damages will be on the front side of the cooler not the fan side. If that helps you searching for it.
