Need help from the community here

[Kris Heiselberg]

Hello everyone

I live in Greenland and bought a 2016 BMW X5 40e from a BMW dealer in Illinios in november 2020, got the car exported to Greenland and have been driving it for the last three months.

I have only had small hiccups with the car so far, but today the hybrid system acted up and it went from electric power to ICE power and the engine started misfiring. Threw an Check engine code thereafter.

I've been using Bimmercode and Bimmerlink since i got the car, so I hooked up the obd adapter and scanned for codes. Got this out of the memory error section:

1 error

A couple of things I recognize and one thing I can explain.
The exhaust flap code, is because I've pulled the fuse for the exhaust flap, to have both exhaust pipes open all the time.

At on point, my wife got home from work and plugged in the car to charge and the main fuse in our apartment got triggered and cut all the power in the apartment. After that, I switched the charge settings in the car to reduced charge power.

And had the car washed last week, but we have -5 to -10 degrees celsius since its winter, but the car ended being washed twice. First time it wasn't done properly, but the car sat outside in freezing temperatures until we picked it up and then got washed again the following day. A couple of days later, we had water pour in through the buttons in the roof function centre. Probably from the sunroof drain plugs being frozen and the water in the sunroof channel got thawed up from the drive. Thinking something may be shorted in that area, as long as there is some water in it.

But i need help from this community, as there are no BMW dealerships here in the city I live in, nevertheless the entire country. So I'm on my own here, at least for the diagnosing part.

Anyone got any ideas what's going on with the car? I've downloaded the error report from Bimmerlink and cleared all the codes, car runs fine right now. But I'm expecting the problems to return at some point.

Permanent error memory should be the one to look at in Bimmerlink. The list you posted is not relevant for now, it contains all sorts of errors which are not active anymore.

For more thorough diagnosis use ISTA.

I guess since your cleared all codes, wait to see what pops up next.
And check your roof drains to see if they may be plugged by dirt as well. There is a thread on here about that.

Hi Kris

I also have the same car (produced late 2015) imported used from the US. BMW had to replace a broken cell module (1) under warranty in my car. Here is the story:
My car also started to behave strange. Battery related messages came on the dashbord display: Drivetrain: vehicle cannot be restarted and the car went into limp mode. Further inspection with Bimmerlink showed lots of messages: The errors became more and more frequent over several months before I decided to deliver the car to BMW - BMW then used 8 weeks to fix the car..they had no spare battery modules.

When these battery errors occurred during driving you could feel a kind of shockwave in the engine/gear system and all the battery error messages was often followed by a lot of misfiring messages on all cylinders, so the battery trouble clearly inpacted the gasoline engine: lots of error messages: all about misfire:

I did search Internet for all these messages but there was very little information. To fix the x5 40e, the High Voltage battery had to come out the rear hatch. They removed some parts of the rear interior and disconnected the aircondition system that cool the battery. Then they uesed a lift to get the battery out. My battery had one bad cell module, so the messages on the bimmercode was pretty accurate.
Your messages also indicate that something is brewing and that you should contact BMW to check the battery and the warranty.(this is not a cheap job - they told me this is 2-3 full days of work and testing)

So I got my car back in March and now two months later I discovered some new battery related messages inBimmerlink:
Accumulator-management electronics
3 errors
21F1F7: Activation prevented - overheating protection
21F156: Preload - Sbox preload condition not met
21F21C: HVS: SBOX - communication error
I do not know what they exactly mean, I searched Internet and did find your request for help, so I wanted to tell you about my X5 40e story..
