Safety wishes to all


W219 550 m273 (2010) 155k miles on it, no check engine light, no codes, runs smoothly without any problems..

Sometimes i noticed that it cranks longer than normal ( 7 to 8 seconds ) not in cold start (In cold start it starts normally) , but during the warm start sometimes (Rarely) i noticed it takes longer time in crank,

I drive the car in a hot zone (North Africa),

I need to know what makes it cranking longer, the problem not frequently happens, but i think should i know what was senarios can make it crank like that..

Note: Actually the problem is rarely happens and its happening in warm start not COLD !!!


Thx so much

 

I have this same issue with no error lights or codes on my w207, nobody seems to know what it is. When it long cranks have you tried tapping the gas? When I tap the gas and it starts right up.

 

Same issue...
MB service technician says - clogged fuel injectors or fuel pump failure.
I will try to diagnose it with Xentry.

 

Too bad the tech couldn't give a more definitive answer. Any luck with the xentry? I'm guessing mine may be a similar issue. I was going to try replacing the fuel pump myself to see if that fixed it.
