Also, this happens only for the first 3 calls. From the 4th call onwards, no problem. Maybe this is related to the time it takes and not really the number of calls I don't know. I called George on the 24hour Infinity Cars helpline but he has not encountered this problem yet he says.
I'm very very skeptical about sending it to the workshop because they just love to keep the car with them for a week at least even if the car has merely sneezed.
Anyone faced this problem?

Try fixing an appointment with the dealer to get the diagnostic report. It takes maximum 15 minutes to run a diagnosis check.

Ask them to check what i Stage your car is in and in case there is an update on of the i Stage available.

Do that after you have tried using an alternate phone as stated in the earlier post.

The workshop visit if the appointment is fixed should take two hours max.

Unfortunately neither do we have a choice to add options in India nor does the India site clearly state what options the car comes with.

Anyway, to cut a long story short, I was able to activate the same by:
a) Patching a CAT5 cable to a OBD connector
b) Using esys to activate the EBT option on the Head unit

While I was at it, I would have also liked to update the access system to set car's Auto Start/Stop function to start in the last used setting (e.g. Off) when the engine is started

However I did not do so as mods on the access system may end up having an impact on the warranty

Experimented a bit more to activate screen mirroring

Couple of shots of it in action - The first shot is google maps , second is Nav on google maps and the third is the built in Nav

Is that really possible? This would sort my life big time
Can I do it on a 2017 X5?

Of course it's possible.. how else would you see google maps on idrive in the attached pics?

I presume the x5 MY17 comes with idrive 5 and the NBT Evo head unit (you can check under maps>version to see if it says Evo)
If that is the case then it can be done on the '17 X5 as well

do note this is screen mirroring (pure replica of your phone screen) which means idrive controls don't work when in mirroring mode
having said that, nav guidance comes from the car speakers

That looks neat, can you describe more on how to activate/use this? Not sure if they have upgraded Idrive to version 5 on X5 yet ( the one's with tiles like on new 7 if that is what it means) & does system allow to mirror screen when the car in moving?

The hardware supports it by default but mirroring is not enabled
There are three steps to the process of enabling it

1) Get a OBD-ethernet cable or make your own - I did the latter - ordered a OBD2 male connector from ebay and patched a CAT5 cable to it (just search for OBD-enet schematic)

2) Install esys (BMW ECU diagnostics software) on a windows laptop (google for how to get it)

3) Within esys,I did the following

a) Updated the FA (vehicle order) to include 6NW (instead of 6NH) and updated the HU ECU (there are 22 ECUs in total - leave the rest untouched) to enable 6NW (enhanced bluetooth that supports two simultaneous phones plus messaging)

b) Update the HU ECU (HU_NBT2 for me) options to activate WLAN and miracast (flags nicht_aktive changed to aktiv)

once the above is done,you should be able to add another phone
In addition,you will see your car appear as an option in the screen cast menu of your phone

Just to add, idrive 5 = the one with tiles as on the BMW 7

Not sure about iDrive 5 and what y'all mean by tiles but it does say NBTevo.

Thank you so much for this detailed procedure!
Will this affect the warranty?
And will it affect the iDrive system in any other way like bugs, errors, etc later on?

Does your X5 has a touch screen? If Yes then it's latest else it will be from last Year. You can also buy OBD Cable from BMW Dealership- have a look at this accessory.

Warranty- Well, it definitely shouldn't impact the drivetrain warranty
As for the HU warranty, I guess its anybody's guess
Its like jailbreaking an iphone or rooting an android - You should be fine as long as you know what you are doing




As for bugs/errors, again hard to say
Having said that, you can (and should) take a backup of your original FA codings and ECU configuration of the ECU you are mucking around with so that you can revert to the factory setting if you face any issues

That is one ridiculously overpriced accessory :O
From the description, it appears it is a BT or wifi OBD dongle with an app for your phone

Regular BT or wifi dongles that would do exactly the same cost around 600 and 1K respectively
In any case, wireless dongles won't work (at least not easily/reliably) for ECU coding and it is far more convenient (and safe) to use a wired OBD-ethernet cable
Mine cost me of all of 500/- and 30 minutes of my time with a soldering iron and crimping tool


PS (and warning): I suggest you do a fair bit of research to understand what you are doing.
The original reason I delved into BMW ECU coding was because I needed to disable the 2nd misplaced keyfob on my old E84 (which was done via disabling the 2nd key on the access system ECU)
Because of the above (and also because I have a fair bit of background in firmware level changes on regular electronics) , I was already comfortable with the underlying concepts and wasn't particularly worried about making an error when mucking around with a 2 week old F34

However, (just saying) it is entirely possible to wipe out the whole ECU if you end up doing what you aren't supposed to which would turn the car into an expensive paperweight that would need to be towed to the workshop

Hi Everyone,

I have been going though a lot threads, but have not come to a final conclusion.
I hope you guys can throw some light on this, hopefully soon.
My dilemma is as follows:

Current variant: 2014 320D(F30) Sports line
Current tyre: 225/50 R17 Bridgestone S001 RFT
Current Wheel size: 7J x 17 BMW 5 Spoke sports variant wheels
ODO: 35,600 KMS

So a tyre change is due asap!

I have been wanting to upsize to 245/45/R17 (the % diff. is within 0.6%)

For pure cosmetic/ Aesthetic purposes & better ride comfort

Even though I hit the highway very often, I'm sure a 225 section tyre is good enough.

I am also purchasing a space saver kit from bmw as I'm shifting to non RFT tyres.

- should I upsize..? if yes then..
- should I go for a squared or staggered set up..?
- will the new tyre width exceed the body(wheel arch) of the car..?
- Will the upsized tyre hit the inner wheel wells of the car body..?
- Can a 7J x 17 wheel accommodate a 245 section tyre (I know the upper limit is 225, but I've seen people upsizing to 255 on a 7J x 17 Wheel)

Tyre options in my locality and taking my preferences into account:

225/50 R17: Michelin Primacy 3 ST

245/45 R17: Michelin Primacy 3 ST, Michelin Pilot Preceda 2, Pirelli P7's

I personally would prefer the 3ST as i have them on my other cars, and i think its a great comfort tyre, I'm not looking for a high performance tyre any more.

But I'm definitely open to suggestions on the above dilemma and tyre options.

I would love to upsize to a 245/45 R17, but wanted to make sure that safety is not compromised.

Could use some help people!!

The RFT to tubeless switch will take care of any ride improvements you would expect from 245
Would suggest you stick to the 225
I switched to P7 tubless on my old X1 and the ride was a lot softer post the change

Hi, Thanks for the suggestions.
RFT to tubeless is a no brainer for me.
But really want to Upsize to 245. So wanted clarity on some other queries which I've mentioned in my post.
Any thoughts on that..?

[Akshay1234]

On a 320d the 225 width is more than enough. If you do want to upsize to 245/45 you can, but I am not sure if they will fit on the rim. But the car doesn't have enough power to warrant an upsize. In 225/50 17 you can look at Yokohama Advan Sports. I am using them on my F30, and the Advan Sports are one of the most premium tyres by Yokohama, comparable to Michelin Pilot Super Sports, etc.

The 392 style rims on the Sport Line (Pre-LCI and even on the LCI) are 7.5J in width.

Max recommended would be 235s which would give an odd size of 235/50-r17.

I'd personally go with either Michelin Primacy 3ST or Yokohama Advan Sport V105 if you can find them in 225/50-r17 as suggested by Akshay.

The only way to put wider tyres is to get wider rims with different offsets and so on and so forth.

On a car like this, better not to choose form over function especially when it comes to wheel-tyre combination.

Ignore the guys running w i d e tyres on narrow out-of-spec rims...

Thanks a lot for the recommendations.
My bad regarding the wheel spec, it is in-fact 7.5J x 17
Ive finally decided to move ahead with the OEM size of 225/50 R17
I agree with you that no point putting form over function here.
Purchases a set of 4 x Michelin primacy 3 ST for 44K total @ 11K each
+ BMW space saver kit for 25K
Thanks a lot guys!! Appreciate it
