ISTA Scan Before Buying a Used X1
Before buying a used F48 X1, an ISTA scan should check: airbag system fault codes (common with unknown accident history), xDrive module coupling wear codes, DCT clutch adaptation data, CBS counters, and B48 water pump efficiency graph (if xDrive20i/25i). This RM 100–160 scan can prevent a RM 5,000–15,000 repair surprise.
