I have some trouble with my French numbered bmw 1M,
It is what we call in France the goat

It means that it makes holes in the acceleration

I have an engine defect that lights, I will tomorrow, disconnect the battery, 15 minutes to reset the boxes. (I had left the key in the ignition by removing the battery...)

The module window, flashing, etc no longer works so I was unable to bring the car home from the garage.


I however would echo what research Monday, however could you help me on the following points:

How do this ?
I don't understand this explain ( i'm french )

I have done change the N20 3.5bar TMAP

DONE

I use Normal gas so : map 1 - 2 or other ?

I don't understand this too

okok i go try in map 2
