I Drive Message "increased emissions" on 2004 530I
I am a recent member to the BMW family and purchased a 2004 530I with 104000 kms. This week after fueling up the check engine diagram appeared and the message on the I Drive screen reads " Increased Emissions". I checked the gas cap and ensured it was tightened correctly and it was. The light remains on. Can anyone tell me what else it could be related to?
Thanks in advance for your assistance.
