Ive been logging the temperature of the coolant for the last 2 weeks and no matter what driving style and current climate my temps always level off around 78-80c Took this to BMW thinking in their genius they might actually look at it but no, got a phone call today saying theres not a problem with them!
Will ring them tomorrow again to question their EGR "testing" methods!!
for what its worth it seems easier to change them yourself!!!
