fault in the c450 amg

Good afternoon, I wanted comments that my c450amg from a year ago until now has been doing 0/100kmh very very weak, it goes into protection mode, but it does not leave any fault code,
Also from a season to here it gives us a fault called p0000 and it has stopped making pops even if we delete the fault, Mercedes does not know and my mechanic is going crazy, greetings, the car has stage 2 plus a watercooler and intake

'15 C400 and '15 ML350

I would start with reverting back to stock tune. What company did you use for the stage 2 file?

Good morning, sorry for the delay, my melody is made by a guy from Spain. He tells me the problem of the pops is due to the lamdas probes, the car makes the pops but as soon as it warms up they disappear, we still don't know why the car launches so slowly , 0/100kmh in 5 seconds... like something limits and doesn't let out hard

Check the diaphragm in the Vacuum Pump valve.

Then order a Vacuum Pump Valve Repair Kit from eBay. Mercedes or Ford Ecobost will work.

Does anyone have the Mercedes or ford part number (or link to buy)? I'd like to get an original one to replace mine.

Regards.

No part number available? I've seen lots of valves on ebay but I'm not sure if they are cheap knock offs that will work for a month.
Anywhere to get a reliable OEM one?

Regards.

C 43

140k miles on my C43. Car was oddly soft off the line but still went OK at speed. Inconsistent. Car is stock, no tunes, etc.

Fixed this part (you'll need a shorty screwdriver, Torx) to get it. You can get at the screw, but it is blocked by the dipstick.

$10, and my valve diaphragm was missing. Picked out the back plastic part of housing from pump.

Replaced Car now drives well again.

Weird thing to have go and hurt driveability this way. No check engine light. Just drove "meh" till you hammered it, at which point it would go....
