Hello
First of all, excuse for my terrible english, i'm italian and a need to use no translator.
My selespeed has a probelm: i parked the car by nicgt, the mornig after she don't start, cause the change is in "R", and the engine don't turn. I push the brake, i hear the clutch actuator, i hear the change actuator that tries to put the "N" , but the change remains in "R" (but really the car is free, she is in "N", i pushed and she moves; i think i parked in "N" as abitually i do.
I disconnented the battery for a log time and for more times, nothing changes.
I have no similar troubles (and no troubles too) in the past (i have this car from 5.000 km, the car has 150.000 km)
The oil level is OK,
the pump starts and oil pressure is correct (i tested with Fiat Examiner, 52 Bar, like 45 the pump starts),
the switch on the pedal is ok,
there are no electrical troubles (i tested with examiner, no errros, and i checked all the contacts, included the N20);
if i launch in examiner the "remove engaged gear" procedure, the monitor signs "N" for a half of a second and then back to sign "R"
Today i disassembled the battery suppoort, and i checked teh two accesible potentiometer (not yet the third placed behind the robot);
if i turn manually the first potentiometer near to me, nothing changes; if i disconnect the pin of this potentiometer, the monitor signs "R" and "selespeed error";
if i turn manually the Second potentiometer (more higher and more back), nothing changes; if i disconnect the pin of this potentiometer, the monitor signs flashing "N" and "selespeed error", and the engine can start.
I interchanged the two potentiometer and nothing changed, so i think they are ok.
Now i hope to find the defect on the third potentiometer; if you have some ideas or suggestiones for me, please help me.
Now i ordered an VAG cable to diagnostic by myself via fiatecuscan, cause the examiner was on loan and I returned.
Until now i did all by myself, i'm a motorcycle mechanic, but i'm really in trouble with the change of my beloved Alfa!!!
Thank you for your attention, and for all the suggestions/help you can tell me, too!
