How to Choose The Best BMW ENET Cable for BMW DIY Coding?

This blog is going to show you clearly how to choose a best-quality BMW ENET Cable for BMW DIY Coding. Is there any tips? Yes! Check below:


So-called BMW ENET cable is used for all BMW F series coding in conjunction with the programming software E-sys and the Psdzdata.

That is to say, if you want to do DIY coding you need this BMW ENET cable to connect the coding software with your car!


Here is what you need to know to start your journey in the coding world:

Tip 1:

All ENET cables are the same! You don’t need to buy the most expensive one because they all do the same thing.

This however doesn’t apply to K+DCAN cables for E series coding because they are completely different.

Tip 2:

The BMW ENET Coding Cable for F series is basically an Ethernet to OBD2 cable, the Ethernet end for your laptop and the OBD2 side for your cars connector.


How to select an ENET Cable with good quality?

You should check if it’s tested and soldered well and never had an issue with it (5 feet length is enough).

BMW ENET Cable using tips:

  1. When connecting to your car through E-sys, make sure you set the ignition on without starting the car. This is important or you won’t have the option to connect through VIN (it will be grey under the target menu).
  2. When DIY coding, make sure you place the laptop on the passenger seat or in your lap without moving around too much. If the Ethernet port is not exactly in tip top shape it could move or disconnect.

That’s not an issue when not doing any actual coding but could be an issue when E-sys is writing the values on the module you’re working on. You could corrupt the module data and it`s not the most fortunate of situations.

It can be fixed but you’ll ever never want to get to that point, so always pay attention to what you’re doing.

  1. When disconnecting the Ethernet port, don’t just pull the cable! Always press the top side to release it first.
  2. Most F series cars will have the OBD2 port under the dash, above the pedals. Location of the OBD2 port is where the BMW ENET cable is connected.

That’s all. Hope it helps!
