W212 E200 2012 Automatic engine stalling

Yesterday when I left the house (engine was warm) as I was about to make right at an intersection, when I let go of the brake so car would move , it jerked back and forth and then engine died
Tried to start it again, same problem , third time the engine worked perfectly until I got to the house.
When I start the engine it makes some kind of rattling , then I put it in either D or R and when I let go of the brake engine dies.
But, if I start the engine multiple times, there’s times where engine starts with no rattling and that’s when I know it will work.
What could cause this? I entered engineering mode and looked at diag codes but there is no code.
( Car is an automatic , 2.2 diesel, has 530k kilometers)

 

I suspect a torque converter fault.

Can you replicate the stalling in park?

Does it really have 530,000 kilometers?

 

no, can’t replicate stalling in park
Yes , it has 530,000km

 

Definitely look at the toque converter then.

 

frankly ,at those km , i would be careful. chances are you will sort that and something else expensive will let go. unless you plan to do all yrself..
