Tx guys !

To X5NSD: this is new to me, thought that these engine required Mandatory high octane (super) for performance. Arr you saying no impact if i switch to regular gaz ?

@ upallnight thanks i should have asked the dealer to give me those code since i already paid $400 for this test ...

But to my question : what about no fix and just place theX5 into heated garage ?
I'm trying to know if this symptoms (missfire) at cold start are a signal that something go wrong even when she is warm and seems to be all good ?

Tx again for your help !!
