Drop idling n20 cold start
Please can someone help me?
I have a BMW 320, n20 engine, 184 HP, on the first cold start, only when decelerating does the idling decrease, drop, after which it recovers. The rest of the starts work fine. It has no error codes! For this problem, several parts were changed without success: -Thermostat -spark plugs - Bosch injectors -original BMW distribution - engine temperature sensor -MAF sensor Bosch -pvc valve -oxygen sensor 1 Bosch -fuel rail pressure sensor - high pressure pump -o-rings changed at intake -rocker cover gaskets changed All consumables and oil changed at 6000 km Premium fuel and BMW additive |

How did you check the error codes? Did you use ISTA+? After replacing components such as you described, the ECUs need to be reset.
Did you try to reset the throttle and transmission adaptations with ITSA+? Not sure if these methods work: https://www.bmwfanatics.co.za/thread...n-reset.89895/ https://f30.bimmerpost.com/forums/sh...13&postcount=2

Did you ever figure this out? I just got to think that maybe your ambient temperature sensor is faulty.
