Hi,

The issue I am having with the car is that 'Drivetrain' error pops up intermittenly but if I switch off and start again it seems fine again until next time.
I have hooked up ISTA D and it comes up with error 0x11A002 'High pressure fuel, plausibility Pressure too Low'.
So far I have replaced the pump with 2 more working used pumps and still the same issue plus changed the injectors and fuel rail regulator.
Maybe there is a hardware error in DME  but  I was hoping to try updating the DME first and see the outcome.
I am also open to other suggestions from members as well.

I am seeking some guidance on updating my DME ecu, I have working Bmw E-Sys ver 3.25.3 with ethernet cable.

I have managed to as far as read the FA, SVT and TAL calculation under Comfort Mode.
Gone into Expert Mode loaded and Read FA, then selected DME only and verified software availability to be ok.
Next step would be to start the operation...have I missed anything before I start to update?

Thanks in advance
