Hi Everyone! Recently Bought my first BMW its an 2003 E39 525D M Sport Auto in Imola red with cream Leather interior, covered 100k miles. I am going on a road trip in it in about a week to Spa and South France I am going to remove the swirl flaps before going, do I remap it afterwards? I have put a thread in the technical section if anyone can help? Thanks in advance hope to speak to some of you soon!
