Alfa 147 light+menu+central lock+ECU problem. Body Computer?
My problems with a 147 Selespeed 2001 are:
*Sometimes Knock sensor fault code with Check Engine on dash.
*Sometimes refuses closing the door command. I Cant lock the doors. Red lock light flashing on dash whe the problem persists.
*Permanent light failure fault message but everything works including lic. plate light.
I think everything leads to the body computer. Today I got the body computer out, and split off from the fusebox. After reassembly, new fails:
* no response for pressing menu and +- buttos.
* Climate doesnt turns off whe ignition off.
*temporary CODE failure, this times car unable to start.
*temporary Selespeed failure message, but no problem in working.
Would be a good solution an ECU+Body Comp swap? Or is this a certain wiring problem ?
What do you think about the case?
Please help me, its very important.
