Electrical faults x5m 2009 e70

Hello All

Really need some help or some guidance here.

Build up to problem:
Car was driving fine, had a 15 mile motorway journey. Stopped at gym for over an hour. As I returned to the car and unlocked it first thing I noticed was wing mirrors did not open. As I went in the car to start it would not even crank over, the dash lit up with a world of errors. DSC, 4x4, abs, seat restraints, idrive screen not switching on, majority of electric in car not responding windows, heaters etc. Thought it was a dead battery, connected to jump start and still no response. Went to a Halfords next door who kindly got a more powerful jump start, as we walked back to the car and unlocked it. Wing mirrors opened car responded and started.

As I’m driving errors returned, multiple clicking noise behind passenger dash. Went stationary, errors pinging all over and car cuts out. Wouldn’t let me start again unless I pressed ok to all the errors on I drive screen. Following day car was fine until I got back home again. Left for an hour and then same result, only this time it has not fixed it self.

Same errors, still can’t start the car. Checked fuses and all areas for water but bone dry. Idrive screen CIC not responding even when trying to reboot (can hear it trying to reboot). New battery installed and registered, made no change.
Another thing to mention when I have ignition in accessory mode the front wipers are constantly on and cannot be switched off. They only go off when key is removed.
Basically nothing in the car is kicking in due to these errors, can’t hear fuel pump kicking in either. Almost seems completely immobilised.

Just need some guidance or want to know others experience if any.
Someone suggested it could be JBE junction box gone faulty. Is this best bet?
Have also attached the errors recorded from my reader.

Any help or experience would be great!

Thanks
Amit

could be a bad footwell module, there was a recall but i think you are outside of that time period. see attached.

You'll need to work with someone to code it to your car

Its BMW Part# 61356827063

Wholesale is $436, used you can get for $180-200

or here

But there are ton of coding folks on Facebook and other outlets to do this.. Just make sure they've done it before.

Thanks. The FRM controls a lot of the lighting right, my headlights still work would they be affected if this unit is faulty?

I’ve basically got no operation on the gear lever also. Doesn’t light up nor active.
Finding this very strange and annoying as something is obviously stopping the car from starting

With that many errors, it has to be a module, and modules can partially go bad and still work too, hence the recall. my FRM cant be coded right now, but works, i am taking it to the dealer cause i have a 2013, but while it cant be coded, it works still, then it will stop one day or all together..

I would suggest having the battery checked to see if it’s bad. Low battery will cause all sorts of havoc as many of the modules on the truck are sensitive to under voltage issues.

Put a new battery in and registered. Thought it was this as it still had the original from manufacture. No change.

Bought a replacement used junction box. No change after installing this also but haven’t had it coded to the car.
Does this need to be coded to the car to see any difference. I thought if it was the problem it may have let the car start at least?

Same errors, 4x4x abs, seating restraints, tilt sensor, wheel speed sensor etc.

I wonder if my I drive might have something to do with it. It doesn’t switch on right now but before any issues I was living with it booting up 5-10mins after car is running. Almost like it needed warming up.
Currently I car hear the main unit trying to power but nothing else happens. No screen or controls active. The eject button works though!

[amit710]

Ground straps from what I can see seem ok to. Done a bypass just in case but no differnce

[JellyStyle]

I still think its a module that went bad, too many errors for a single error from my opinion. HAve you tried to connect ISTA+ and see what the recommendation plan is to correct?
Any smart coder can diagnose this, if you don't know anyone, i can put you in touch with Valentine or someone (there are tons on Facebook too)

[amit710]

Going to give a few of the local BM specialists a call tomorrow.
Think you are right it is a unit but need more advanced diagnostics too hopefully pick out the right one rather than a bit of guess work right now.

Just an update if this helps for more advice please.

As I put the key in the ignition there are less errors, as I press the brake pedal it responds with 4x4, dsc etc.
does this mean anything or still spontaneous errors from something else?

Jajja saying it could be related to FRM module because a lot of what is not functioning relates to this module (I’m going towards this) even if part working.
Not something I have looked at yet but there are places here that diagnose and repair if it’s just a wakening/ booting issue as such.

Keen to know if anyone else has had FRM module issues and symptoms?

If you can’t tell by now I’m trying to avoid getting my car to a garage, only because it’s in a difficult position to tow…

FRM module is a recall, if your ride is less than 10 years old or 125k miles.

these guys repair them, so you don't need to have it coded for 290, not a bad deal.

To update further. Have managed to find out that on the rear fuse box there are a cluster of fuses which have no voltage going through them. Looks like this is related to my issues.

Can anyone advise what my next steps should be?
Where do I track these to?
Is there a relay may be defective?
Faulty fuse box?

I feel I have got closer to the issue but need some guidance on next steps

I recall at least one other posting where their rear fuaebox was failing, so uncommon. BUT seems relatively easy to buy and replace to at least get that off the list. Then, if not solution, go to each fuse and back track to where voltage stops.
