Disabling safety features

[ttonks993]

In the process of turning my F30 330D Auto into a track car. I am very accustomed to driving cars with no traction control or ABS and I would like to set my F30 up as such, but I am having a few issues.

First I have pulled fuse 58 under the bonnet (main ABS fuse), all is well I can get the wheels to lock up. But for some reason the gearbox will automatically shift into neutral during moderate braking. I need it to stay in gear. Can this feature be coded out somehow?

Secondly the vehicle is stuck in comfort mode now I have pulled the fuse, I need it in DSC off mode. The traction control system IS NOT working and I can get the rear wheels to spin but the E-Diff isn’t working and only 1 tyre is spinning (I’m guessing due to the wheel speed sensors not working). What s the work around for this? A proper mechanical LSD?

Thanks in advance

Doesn't Sport+ mode disable most of what you want anyway?

But I thought the e-diff used the ABS system/sensors to control wheel spin (using 'differential braking), so by disabling the ABS you've likely disabled other systems.

But a proper LSD would probably help too - but I don't know what errors will pop-up when the e-diff function removed.

Maybe INPA/ESYS may be able to code things out further?

Holding down the traction control button for c5 seconds will switch it off fully, sport normally defaults to allowing a little slip.

No way of getting around the ABS to my knowledge, without getting a full-on coding specialist.

Biggest question, why a 330d auto? Can't think of less suitable car as a base (beyond a 4cyl diesel)

Apologies for going off topic, but why are you turning a 330d auto into a track car, rather than buying a manual?

The diesel choice i get for quirkiness, I had a 330d and it was rapid. But not sure why you'd stick with an auto?

[ttonks993]

It is my old daily, after buying a new one. It s fairly modified so was cheaper to turn it into a track car than sell it and buy something else.

Does anyone know someone who does E-SYS BMW coding in the West Midlands area?

If you do ei into the menu you will find 'coast' in ECO Pro settings, I don't know if that is your issue concerning going into neutral.
I assume it's a sports auto, so you can drive it manually.

Simple answer; why not?

Because it’s a hard way of doing it.


OP, your car is not the right base for what you are trying to do, and TBH I would question why you would want to bin ABS anyway .

If you are ok living with the compromises in exchange for the savings then that’s fine but in the end if you want a car with no gadgets you are probably better off just getting an E36/46 or even 92 where things can be modded more easily.

For coding in West Mids try Zed Coding in Birmingham, even with E-SYS and all the other gadgets not everything can be bypassed but they are very good.
