BMW 335i HFS-3 power problems
Hello Everyone,
I bought a used kit and want to know if i got ripped off. I have a hfs-3v2 and i started to hook up everything. I have hooked up everything except the ecu/user plug. I wanted to know if the unit should be on? for example the lights on the gauge. I have power at the power plug. 12v red Ground - black and white 12v head lamp switch- purple Does that mean i need to have but a new box unit? |

Re: BMW 335i HFS-3 power problems
Can you take a picture of what you have and the serial number of the controller. For the 335i , you need the green harness but the earlier batch of the HFS3-v2 requires some mods from the factory to bring it up to date with the second batch of V2. The serial number will allow me to check this for you.
We do not charge for making the mods but you have to pay the return shipping.

Re: BMW 335i HFS-3 power problems
Not sure what you meant by engine light stays on. Are you referring to the HFS3 controller or the car.
The circuit board is quite old, it may need to be return to be upgraded or just purchase a newer HFS4 controller. The HFS3v2 was not strictly configured for the 335i or Di engines. The fuse is not properly inserted into the holder. Can you take a picture of the underside of the circuit board. I like to see how it is configured.
