Hello mates,

Need your help because I am out of ideas. Car is E60 530D. After injectors replacement car starts for 5 seconds and dies, each start shorters dying time. Fuel pump in tank checked - works perfect. Rheingold throws no errors (everyting is fine). Tried to disconnect MAF - nothing. Injectors were programmed to dde. Cas was updated bu SP daten 56. What could be more? No errors via diagnostics. Any help is appreciated.

Try to synchronize cas with EWS maybe it help you

I have done alligment like 10 times, every time it was succesful, but engine still stalls after few seconds.

Then you have mechanical problem if no error codes.

CAS with EWS?!?

Check if new injectors need to be calibrated to DDE by enter correct number from body.

I would agree with doctorabg you most likely have a problem on mechanical side. But it may help if you could tell us more about it. Why injectors were replaced? Are brand new ones put it? Does engine sound normal for those 5 seconds? Does it run at stable idle rpms and suddenly dies or does it struggle to reach idle level? Does it react to throttle for those 5 seconds?

Wild guess could be blocked air intake (what is MAF reading while it runs?), blocked exhaust (can you feel it?). You can also look at live data and look for any anomalies during those 5s. Check diesel amount flowing through injectors return line as well.

Give us something, we are not fortune tellers here

You mean DDE and CAS becouse EWS and CAS are the same thing and there is not EWS on E60.

Injectors were replaced with used ones, corrections of "new" injectors was writen to DDE. Engine sounds normal and idle is normal for those 5 seconds, second start and engine works 3-2 seconds and third time only cranks. Tried disconect MAF - rough idle from beginning of start than. RPMS are idle for those 5 seconds with MAF. It runs in idle and than starts to die but not so suddenly (looks like someone turns of fuel supply). Engine reacts to throttle if it is kicked down before engine start (but only goes to ~3000rpm). If throttle is kicked down after engine is on - no reaction.
Today "new" injectors were replaced with old ones - same thing. Nothing more were changed, only injectors. Before this car was running fine (only a lot smoke on throttle and rough engine idle, diagnostics showed 3 almost dead injectors).
I would say it could be rail pressure sensor, but during those five seconds it is normal 300-350. Didnt checked MAF readings during those 5 seconds.

Leak off test on injectors, guaranteed, 1 is not good, disconnect rail pressure sensor and try starting and see if it holds.


also check for leaks on regulator valve and the back of pressure rail.
