All lights on dash but no cranking
HELLLLP!
My car won't start first thing in the morning after many attempts. Left for a random time it starts as.normal. no codes, new batteries, and when started all is perfect. Last 5 days this has happened and randomly over the last 2 months.

If the engine is not cranking, then I would check the usual suspects, such as wiring to starter solenoid and starter relay. Is there a signal from Passenger side front SAM to starter solenoid.
Some other members have suggested no cranking could also be due to the Crank position sensor, but check for power to starter solenoid first.

Jump pins 30 and 87 on the starter relay to test the starter circuit. Unlikely to be the relay or the starter motor though; starters don't fail intermittently, usually they crank slowly while drawing excessive current. If it spins normally then you might have a failing EIS module.

Sometimes hitting the starter with a hammer or wrench while someone else tries to start the engine may get it to work. In which case, that's exactly the problem and time to replace it.

Don't know about Mercedes starters on older cars, but starters can fail intermittently or just completely all at once. Not saying that's the case here, but I wouldn't rule it out completely Brother MFC-1770 [4/24] Notice disclaimer of warranties for usa and canada.

@yovenim you are describing an almost dead battery that isn't holding a charge. New or not, if it was ever left to drain down, it's likely toast.
