SOURCE: Get DTC P1582 which is
DTC code EOBD type: P1582 - Idle speed adaptation - limit reached.
Probable cause: Intake / exhaust leaks, air system, fuel pressure / pump, injector(s), EVAP canister purge valve.
1. Check intake system for leaks: Spray some carb cleaner product around intake manifold area, engine idling. If engine idle speed revs up there are intake leaks. If engine idle speed doesn't change the intake system is OK.
2. Check exhaust system for leaks: Inspect entire exhaust line for black tracks of soot. If you will find something bad repair & replace damaged pieces.
3. Fuel pressure checking:
3.1. Ensure ignition switched OFF.
3.2. Connect pressure gauge between fuel supply pipe and fuel rail.
3.3. Open gauge tap. See picture below:
3.4. Start engine. Allow to idle.

the 1582 code is a flight recorder code meaning that at some point one of the following has happened: the inertia switch has been triggered,throttle body signal has triggered the limp mode,the engine starts but stumble and then shuts off,or engine fail to start,or a engine stall has occured.This is what causes this code.If the issue was resolved,clear the code becuae it can become permanent and although the car will run fine the code will be there without a mil showing.

1 Inertia switch activated
2 Throttle Limp Home mode
3 Engine starts and stumbles
4 Engine fail to start
5 Engine stall
If none of the five conditions occur, check: Inertia switch to ECM circuit:
short circuit to B+ voltage Inertia switch failure
You can check the Inertia switch status on the Instrument cluster Diagnosis, see http://www.bluejag.co.uk
