? Mileage. ? Warning lights. U said u have the problem since new.

Stalling ain't good & neither is the 'bump starting' after that!

Get it scanned w/ a good scanner. Check DPF data, diesel common rail pressure, crankshaft & camshaft sensor data. The crankshaft & camshaft sensors are synchronized every time u start the engine. If synchronization is lost it will be recorded & doesn't get deleted.

 

No warning lights illuminated. Currently mileage is at 66k. Driven 250 miles per week. No dpf faults.
I wasn't aware using the momentum to restart the engine 'bump' was an issue...? Not that it had ever restarted like that after such an event. It has always required turning the ignition off and restarting. Prior to and after the event car runs perfectly.
If the cam/crank sensors lost synchronization surely it would trigger a EML, besides it has been doing this occasionally since new.
It's an issue that happens maybe once a month, so not a massive issue just wondered if anyone else has experienced this behaviour?

 

If it's been happening since new did you take it back to the dealer, if so what did they say.

 

No didn't take it back to dealer. Initially put it down to being too fast to raise the clutch and not giving it enough throttle and it only happens very occasionally. They would never have been able to reproduce the fault. It's that random..

 

I've had experience with 2 cars, not Dacia, that exhibited the problem you describe in both cases it was the crankcase position sensor that was faulty. In neither case was it detected with a scanner.
Hope you find your issue.

 

I've had this happen on and off (pun intended) with several Dacias, and I've put it down to the stop-start mechanism kicking in when I least expect/want it.

Try disabling it for a while, and see if tge problem reoccurs...
