i3 Coding Screws up Wireless Internet "Connected Drive"

Coding my car was clearly the best upgrade I have done. Finally I was able to get my car to do what it really should have from day one.

It took me a while to figure out, and make sure I had my ducks in a row, but I was ultimately able to use the cable to code my BMW i3 Rex. I successfully hooked it up, ran the included software, and was able to change things like: get rid of the annoying welcome gongs, get rid of the seat belt warning gongs, enable full use of 2.1 gallon gas tank, enable AM radio, and change it so my audio system turns off automatically when I open the door to exit the car. All things most anyone would want, but I guess that's besides the point.

Back when I was making these coding changes, about a month and a half ago, at the end of the process you tell the coding software to write the changes to the car, and it causes the car to reboot to update the new changes. Within the computer software it said that all changes were written successfully, but upon the reboot of the car system, there was some sort of an error message displayed on the car screen. I apologize but I did not write down what that message was. At the time I thought "oh great, now I've really screwed something up", but the message went away and everything was working as I had hoped it would.

Fast forward a month and a half, and just this week I noticed that my "ConnectedDrive" system would not connect to the wireless internet anymore. I don't really use it in the car (it is 3G and really slow), but I do use it occasionally on my phone to connect with the car for being able to remotely check the car's battery level, and remotely turn on the air conditioner. When I first discovered it, I thought that maybe the BMW subscription with AT&T for the internal SIM on the card had expired. I set a meeting with my local BMW service center to have the problem checked out.

BMW had the car for a day, were able to repair the wireless internet problem, said that it was not related to the SIM subscription, they said it had to do with some sort of error code in the programming, they reprogrammed everything, and now all of my custom coding is gone (but wireless internet ConnectedDrive is working again).

With my custom coding gone, I hate listening to those welcome gongs, and not being able to listen to my AM radio, but it seems like something I did in my coding prevented the wireless internet "ConnectedDrive" from working. Has anyone heard of this? Can anyone offer me any advice, before I go back in there, try coding again, and once again screw up ConnectedDrive? I am going to do it again since the coding modifications are worth more to me than wireless internet ConnectedDrive, but before I do it again, I wanted to check with all of you. Once I code again, I'm going to have to wait a good while to go back to my local BMW service, or I'm sure they will cry foul.

I've coded the same options you have in my i3 and did not notice any error with ConnectedDrive. However, I always use Transmitter to clear DTCs after a coding session to make sure I clear any errors that might be present after coding. Did you do this during your last session? While many of those DTCs auto-clear, some of them don't.

As you noticed though, any time a dealer hooks your car up to ista/p and flashes your car, you loose all your coding so you'll need to do it again.

Hi Gabylonfive, and thanks much for the quick reply. I am a bit of a bumbling idiot when it comes to coding. I merely followed the instructions the came with the cable, and was actually somewhat amazed that I could figure it out, especially given that a lot of the codes are in German, etc.

Anyway, with regard to using a transmitter to clear DTC codes, I definitely did not do that. I don't know what the transmitter is, nor do I know what DTC codes are. Can you expound?
Same issue here...

Just coded my i3. Did a few rounds and about 15 coding items. Now my ConnectedDrive is dead. I'll try to back everything out again and see if it fixes things.

What do you mean it is dead? Try updating if possible. If not, try power cycling by holding down volume button until system turns off.

BMW Online still busted

I get "No connection - unable to establish a conection via the cell phone netwrok. Please try again later or from a different location"

No BMW online service, no widgets. I get a globe with a line through it. I reset all the coding back to factory and still no BMW Online connection.

I tried to power cycle, but nothing happens after holding down volume button for a min or two.

Possible the network is down.

Found a video on Transmitter and clear DTCs. It's an external app that's launched by E-SYS. Watch the video, great explanation. http://f15.bimmerpost.com/forums/showthread.php?t=1033991

Thanks Almaretto....I've given it 4 days and it still doesn't work. I have to get my USB port fixed. It died the same night I was coding. I read elsewhere that a fuse may have blown. I'm hoping it's a shared fuse with the 3G cell in the car.

It goes without saying, that the Internet became part of the human's life. Everything, that surrounds us, is connected with the internet. Moreover, a lot of functions, which couldn't be imagined some years ago, is now easy to made in two clicks. By the way, the firms, which deal with the phones, improve their phones in such ways, that they browse faster, I have found even whole article connected to this term on the https://usave.co.uk/. I was shocked, but Samsung Galaxy S10 Plus is better, then I could imagine. _sl_
