Hi,

I'm hoping someone can help. I have a 2015 seat Alhambra 2.0 tdi. The car starts up but cuts out after a few seconds. If I prime the system with vcds it will stay running for about 20 seconds.

Im getting low pressure fuel rail fault code every time and occasionally fuel pressure regulator discrepancy code.

I've changed the in tank pump, fuel pressure sensor (x2), fuel pressure regulator (x2), fuel filter (x2), and fuel metering valve. I've had my injectors tested and they are within spec I'm told.

I'm now thinking that I'm loosing prime somehow. Has anybody else had this? I'm at my wits end with this car.
