ASXbuyer's guide

The GA ASX is a compact crossover that aged well on paper but badly on neglect. Diesel examples on a diet of short trips accumulate emissions problems fast, and buyers who skip a cold-start inspection regularly inherit issues that were obvious with five minutes and a scan tool. This guide gives you the checks that separate a clean car from an expensive mistake.

This guide covers ten documented issues: AdBlue/DPF/EGR emissions fault, timing belt/chain service risk, DSG/automatic/clutch judder, coolant leak or water pump fault, infotainment/software electrical faults, suspension knocks and tyre wear, brake corrosion or EPB fault, panoramic roof or boot water leak, turbo boost leak or actuator fault, and recall/campaign status. Each fault has a field check and a real repair-cost range.

Cross-reference the VIN for open recalls before you travel, do the cold-start and OBD scan on arrival, and run the emissions system checks on any diesel. A documented GA ASX with clean diagnostics is a practical, low-cost buy. An undocumented one can hand you a repair bill before the first service is due.
