My vehicle currently has F020-15-11-505

What benefits would I potentially realize by upgrading to one of the newer, more recent options?

Are there any negatives to upgrading like lost coding or tuning functionalities?

Sometimes it's big improvements, others, very small things that you won't see. For example:
Auto gear box improvement, smoother gear changes (in case you have an auto)
New layout in idrive
Smoother tach in cluster, less lag
Faster comfort access when locking/unlocking car
Electric tailgate smoother close

Those kinds of things, depends on the version, model etc
There's always a risk but if you follow the correct procedures, it's a small risk.

Potential benefits:
- Bug fixes
- Safety (Warranty) related improvements (e.g. introduction of rev limited)
- Enhanced functionality and support of newer external devices (e.g. bluetooth, support of newer phones and improved integration, etc.)

Do not expect truly "new" features. That's not the goal here.

(Potential) disadvantages:
- You will most certainly lose all your coding or at least most, of the affected modules. You will need to recode afterwards.
- DME lock preventing future OBD tuning (not sure it applies to your engine)

Before an I-Level update, if you have a retrofit CIC to NBT HU, do you remove the emulator?

See my post here

Although with such a old build of F30 (from 2011), some of these fixes might not be applicable.

This is the level that came programmed on my 2016 (F30, LCI).

I see that Ive mis quoted it above, fixed that!

Thanks for pointing that out.

There are resources online to get a better idea of the fixes between a 2015 I-Step and current. Dont expect brand new functions like a Tesla, but expect bug fixes and improvements.

From what I remember, the DME lock only occurs on the B58 engine. So your N55 should be unaffected. I believe some 2016 cars need a I-Step upgrade anyway for the 3G sunset this month, so you may be in for a free ride if your car qualifies.

Has anyone done an I-Step upgrade at the dealership ? Wondering what the cost would be around ...

Free of charge during maintenance / inspection.

Last time I checked, 2-3 hours of labor, plus cost to repair any consequential damages from a failed programming. It's not a warranty or standard maintenance item. The only way you can get a free update is when it's associated to a covered repair like a steering rack swap, iDrive controller replacement, or SIB like the one for the evaporator temp modification.

Ive got a 2013 335i. How would I go about having the cars I-level updated with going to the bull sh1t dealers?

• A laptop running ISTA or ESYS
• Full PSDZ data
• ENET cable or ICOM module
• Power supply suitable for ECU programming (Deutronic DBL430 is what most dealers use)
