On a 2015 BMW 3 Series Gran Turismo, inspection comes first. If the fluid is moderately aged but not contaminated, a drain-and-fill may be appropriate; if the goal is to renew most of the systems fluid after regular maintenance, an exchange can be considered. Our team inspects before recommending either approach.

• Service history guides selection; unknown history warrants cautious approach
• Exchange replaces a higher percentage of total system fluid
• Inspection precedes recommendations to avoid over- or under-servicing
