Hi, I'm trying to fix a p06 ecu.
When i got this ecu it had 12v on the logic side of the board.
I've replaced all the caps and clean the board and that fixed that issue, now the 5v rails are working properly.
Now the fuel pump works without delay and the cel light clears.
I've reflow all the transistors and ICs on the power side of the board.
But the car struggles to start, misfires and hesitates under aceleration and when cold won't hold idle.
If i leave the ecu connected with the key on the 2nd position for 10 minutes it starts well and runs fine. If I turn of the engine then start again it struggles to start and maintain idle for some seconds.
I took some mesurements while with the key on the second position:D11 has 0.48v
D13 has 3v
D15 as 3.1v
D17 has 2.81v
D19 has 4.95v
A1 12v
A3 12v
A5 12v
A9 12v
A21 5.85v
I Hope someone can help.
