pop up fail

Thanks RE92... I kinda understood some of that... the bit about taking it to an Indy!!
Seriously though if the battery was at fault and while I was driving along it decided to shut stuff down that would make sense yes??
I will check fuses tonight and then I have the use of a Carly tomorrow.. failing that I will have to wait until the present climate changes as all independents are closed
Unless someone can suggest one in or near plymouth
 
ISTA+ is quite easy to setup on a laptop but only if you are reasonably comfortable with IT. I would be happy to plug into your car and do a diagnostic but I'm nowhere near Plymouth. Carly might be useful, you would want to reset all codes first then restart the car and scan again, that should narrow it down to active fault codes.
 
Thanks again... I will try Carly and go from there... I can’t find anything wrong with fuses?? Thinking radio etc has gone into limp mode through battery fault??

No limp mode for radio.

If it's any consolation it sounds like your screen is fine. My money is on the hard drive failing, I think we'll see more of these as the cars age as it's a mechanical drive.

If you do a Carly scan and post all the error codes up here we might be able to work it out.
 
Oh that’s a bit of a blow... :( :(
Well I guess I will see what Carly has to say
I’m assuming if I need to swop out the drive, and I can get a replacement , then the new will also need coding in??
 
Ok so plugged in Carly... cleared what faults were there... except this one
00A47E Flap error-Blockade/Hardware error:Internal voltage supply defective. (Central info Display)
Which means what?
Thanks
 
Oh and this one 002D2A Differential pressure sensor, intake manifold:Adaptation ?
whatever that is....

That points towards a faulty motor unit on the popup screen but I don't know why that would stop the radio working. There's no comms faults there so I'd say that's a good sign.

Depending on how comfortable you are with taking the car apart you should be able to diagnose and possibly fix yourself. I would start by taking the screen out and checking all the wiring to the popup mechanism, you could have a broken wire.

A user called AnubisZed did a good DIY on installing an Android headunit, his install video should give you all the direction you need to remove the popup screen: https://z4-forum.com/forum/viewtopic.php?t=113141
 
Thank you Sir,
Just one question... if the pop up screen is working e.g constantly going up and down how would this be the mechanism NOT working???
I’m not confident enough to start taking stuff apart but I will search for ‘How to’... just to see..
Could there be something like a loose connection to the head unit?? Thus no power??
I’m really at a loose end here as to what to do so I do appreciate your help!!

Unless you’ve been in there and disturbed components it’s very unusual on this BMW to have loose/intermittent connectors unless there has been a mechanical intervention and/or water born corrosion...

All the connectors have locks on them, especially the biggies for the ECU’ s and audio subsystems..
 
Hello sir,
No I’ve not been rummaging!!... :?
just trying to think what to do next apart from auto electrician.. if at all possible in present situation!?!!
I’m of the opinion that I need to find out if there is power going to the unit yes??... if so then it’s probably the unit??.... if not then something between power supply and unit...,I know I’m sounding a Luddite but electrics really not my thing!

It's certainly not common but my thought was that it could follow the same sort of failure that we see in the boot mechanism, the snapped wire causing repeated boot operations.

It's understandable, these sorts of faults are tricky even for the dealerships to fix hence why they would just quote for fitting a whole new unit.

How exactly is the unit behaving now? Still popping up and down? DOes it ever show the BMW logo?
 
When Started it takes a second or two then the stern pops up displaying the BMW logo.... a second or so later the screen closes.... another maybe 5 seconds or so and it opens again showing logo... this goes on ad finitum.....
 
OK apologies for the merry-go-round here but that certainly feels like a hard disk failure to me. That's exactly the behaviour you get when the hard disk is removed from the unit or when the drive gets corrupted.

Here's my post about removing the hard disk and upgrading the existing drive: https://z4-forum.com/forum/viewtopic.php?f=46&t=94090

Before you go down a rabbit hole I'll be honest here in saying that there's no guarantees any of this is going to fix your problems but I'm happy to help you with it. The alternative will almost certainly involve a trip to the dealer and a very expensive replacement CIC unit!

The hard drive failure won't show up in Carly because the disk isn't a car module, rather a slave of the CIC module itself, once the CIC module starts it calls the hard disk to spin and then reads the partitions contained on it for booting up.

There's two ways forward here and which option really depends on how willing you are to make assumptions;

1. Fully diagnose the issue before replacing any parts
For this you would need to follow my guide in the topic above, remove the current suspect hard drive and plug it into a PC or laptop using a PATA to USB converter (there's one linked in that guide above). You would need to then look at the partitions and verify they are all present. My feeling here is that the drive probably won't even spin up.

2. Get a replacement drive and try swapping it, see what happens
I found one on eBay which is reasonably priced (£90), the replacement SSD would be £60 and you would still need to format it which will be difficult given your current drive is suspect.
https://www.ebay.co.uk/itm/BMW-E60-E63-E90-E70-E71-F10-F12-F01-F30-Satnav-Navigation-HDD-HARD-DRIVE-cic/333547703321

If it were me I would just go option 2 and buy the eBay drive and give it a shot as I'm impatient but option 1 is he cheapest and probably the more thorough approach,
 
Oh jeez!!... that all sounds a bit beyond me!! I’m not computer savvy whatsoever!😂
Your plans are excellent and I thank you I just think it’s a bit too much for me to do...
I don’t know... I need to determine exactly what’s at fault (or electrician does) and see if there’s a plug and play option? It’s going to cost that’s for sure but i just need it done
I really appreciate your time on this and you’ve probably suggested the best and cheapest ways of doing it

Taking the hard disk out is very simple, you just need a couple of loyalty cards and a torx screwdriver. But I understand about knowing when you've reached the end of your comfort zone.

I'm by no means an expert in any of this, just a nerd who likes to DIY. I really recommend chatting to someone who specialises in these CIC navigation units before going anywhere near a dealer or auto electrician.

I found this guy on Facebook: https://www.facebook.com/pages/category/Automotive-Repair-Shop/Tomtechtronic-idrive-CCC-BMW-Specialist-785709971637894/

Looks like he's fixed a lot of units with similar faults to yours so give him a ring or send him a message and link him to this thread.

It only "feels" or are you pretty sure??

When I replaced my CIC-Harddisk by a SSD in the last year, the first transfered images were faulty and the navigation system did not start up.
But the monitor always stayed open and presented a message, that the navi system could not be booted. With this experience in mind, I would not agree with your "feeling".

Maybe I can check the behaviour of the system, when the SSD/harddisk is removed, as I did not yet place the cover on my CIC-system.

It's hard to say for certain without testing things. I did look at other CIC failure threads where people had failed drives and the boot loop issue with the BMW logo showing and then restarting is the main symptom. Our Z4 is the only system I know of that has a popup screen so finding information about the behaviour of that is harder.

When I did my HDD replacement the screen would not get past the BMW logo without a disk plugged in. With a blank disk plugged in it would boot but all functions would be unavailable. If his disk is present but has a failed motor or platter then it's possible that it causes a boot loop.

The OP could put his ear close to the radio and listen for any mechanical disk noises, any repeated clicking noise is a sure sign of a failed drive.
