BMW e46 330i diagnostic software

[gibson2004]

Afternoon all,

Does any one recommend software which i can view real time data from the ECU? I'm currently getting a noticeable power drop when warm. i have replaced the following:

Vanos has been replaced.
Pre cat sensors replaced.
new MAF
new DISA
Crank sensor replaced.

I have found that if the car was warm and i disconnect the battery for 20min then reconnect. the car is fine, so i believe there is a sensor issue somewhere. I do have a code reader but no codes are showing hence the need to see the data from the ECU.

Thanks in advance

Hi there,
Did you find the problem ?? I have the same with my 2001 330ci.. Also changed "everything" without finding a fix....
