If the 320 uses a two piece magnesium manifold that's simular to the 430/55, and it's leaking, thats it. The problem is, the dealer doesn't have a gasket for the upper/lower manifold halfs. You can try removing it, disassembling and cleaning it, and then attempting to use silicon or something, but I'vs only read of a few who have gotten the seal to hold.
Personally, I'd call a junk yard and ask for the intake. As for the MAF, it's easy on a 430/55 and even easier on a 320.

just got my car back, all i can say is WOW, these benz services advisors are SHADY!!so advisor is telln me i need intake manifold and MAF and says thats whats causing my engine to stall, so i suggested i start off wit the MAF since its the cheapest. he INSISTED i do manifold first, at price of 1200 just for part. and said dont even bother with MAF cause with bad manifold it be a waste of money.
so today when i pick up my car, i tell the advisor if he can show me himself where this crack is on the manifold. he introduces me to mechanic whos been workn on it. so while advisor has a phone call he has to take, im askn questions to mechanic and he tells me that the MAF is whats causing my engine to stall. the bad intake is just giving me a rough idle at intermitten times. i was like wtf, thats not what advisor told me,lol. so i just paid 175 for a diagnosis. i got the Truth from mechanic, he said a new MAF would fix my problem of stalling, which is y i took it in the first place. i dont expect my car to have a perfect idle since its a 2000 clk with 200k miles. lesson of the day, dont trust these service advisors, they just after your cash. im glad mechanic was honest. gona order a MAF from autohause az, hopefully mechanic is right! lol

I hope so too. A bad maf will give a rough idle and can cause the car to stall BUT a crack in the intake can produce those same symptoms. Better to start with the cheaper parts first and work your way up to the more extensive and expensive parts if need so. Just incase, If it is the intake thats giving you the problem and the crack is easily accesable, there are welding rods for welding aluminum and would be a hell of alot cheaper solution to replacing.

i think for manifold they got to do that compression test.. My mechanic did it on my car and they thought it was leaking but it was not!!!!anyhow yes dealership is a rip off .
, my car used to hesitate at 5000 rpm and they quoted me $4000 because htey have to start from scratch and fix everything.
even though the diag tools shows all wires and so forth are good to go.
i ordered new plugs and new wires and did em in front of my house and no prob since...

The manifold is magnesium. It's not going to crack on it's own. Its a non-stressed part that just sits there. Some people have claimed leaks but most of the time its because they've taken it apart to clean/HP tricks. There was one guy either here or on BW whose 430 manifold leaked on its own. He said he never took it apart.

Yea probly just a line. Test it out on your own using a can of starter fluid, spray around the area they sprayed to try to pin point the location and do what ever nessecary to fix it. Dont go nuts with the spray and spray the crap out of everything lol! Its definately a vacuum leak if the idle changed while spraying. Take off any engine cover you have on it while testing. Good luck!

2000 CLK320 coupe
2000 Mercedes Benz CLK320 and mine started to not only stall but it would
turn off while driving. I let it sit for about fifteen minutes and then it would start again. The motor would turn but would not start. On this forum someone mentioned the Crankshaft position sensor. Replaced and no more
problems. Maybe that is your problem. Regards

Ps. It is also a very non-expensive fix and you can do yourself. Part costs 75-100$

99CLK320,
I took mine in for an alignment after changing to lower springs & sport shocks at 30K. the service mgr told me my lower control arm bushings were shot and my valve cover gaskets needed replacing. "At only 30K" I asked. Yeah, he said. NOT I said.
