Pewnie nastawnik biegu jałowego jest walnięty w przepustnicy. Najlepiej podłącz vag i sprawdź czy masz błędy, wykasuj je i spróbuj zaadaptować według tego:
Idle Speed Adaptation:
With engine warmed up, at idle:
[select]
[01 engine]
[Adaptation - 10]
Enter channel 01
Enter an adaptation value between 124 and 132
[save]
(May require a Login of 01283 or 11463, depending on year or model)
Throttle Body Adaptation:
Turn the key on but do not start the car.
[select]
[01 - Engine]
[Measuring Blocks - 08]
Enter Group 060 (may be Group 098 on some cable-throttle cars)
[Go!]
[switch to basic settings]
Once you do this you will see the top right display say ADP RUN. The TB
adaptation is being done as soon as you switch to basic settings. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in basic mode for about 30 seconds, then switch back to normal settings and you're all set.
Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!
