Re: REX Won't turn on

Yes I have an update now.
I've got the car back yesterday after 2 weeks (!!) at the dealer.

They exchanged the fuel pump and the relay belonging to the fuel pump.
However this did not solve the problem.

After a long search, they found out, that the relay of the fuel pump is next to another relay.
And although the exchanged the relay for the fuel pump (according to the dealer documentation from BMW and even a BMW instruction movie for the mechanics), it turned out that the relay next to the supposed fuel pump relay, was the actual fuel pump relay.
So the position of the fuel pump relay was wrong in the official BMW workshop documentation and in the BMW-instruction movie for the mechanics!!

So this could very well be the reason that similar problems in oter i3-REX BMW's could not be solved.

@Zwerius, thank you very much for the feedback! could you scan the paper work or part numbers that needed to be changed that would help my mechanics find or diagnose the problem.

If you can PM me those informations that would be greatly appreciated!

Thank you very much!

@slac10:
Sorry, but I don't have partnumbers or any paperwork.
I just told you what the mechanics told me.
I didn't even see any of the parts. No idea where they are in the car.

@Zwerius,

It was the fuel pump relay on my car too! Glad you gave me the hint!

I replaced it myself saturday and now it's running fine.

Thanks,

Steve

If you visit this website you find a video showing the exact location of the fuel pump relay behind the glove box.

The easiest way to get to it is to remove the glove box (6 or 7 screws) it is the relay on the right.

-I've had 2 "Drivetrain Errors" intermittently since November 2018 on my Dec 13 REx. 1"you can continue your journey", then always before the end of the journey "electric range only, go to BMW I-service". My local non-BMW garage said there were "HV Cable Resistivity" faults in the stack.

-I took the car to a UK BMW dealer, who replaced the injectors and pre-cat NOx sensor and reprogrammed the car

-the new BMW software is buggy, and causes the charge indicator to get stuck to the left even when accelerating

-the 2 Drivetrain Errors returned

-took it to another BMW dealer who diagnosed fuel pump relay and HV cable

By now, I doubt all BMW dealers because I don't see why replacing the injectors and NOx sensor would cure the HV Cable problem.

We'll see what happens and I hope it's just the relay now.
