BMW 3 Series2018

• Timing chain issues common on 1.5L turbo engines — listen for cold-start rattle and budget €800–1,200 for tensioner work before buying.
• Direct injection carbon buildup causes rough idle and hesitation; walnut blasting costs €400–800 and is preventative maintenance worth asking about upfront.
• Median mileage at 63k km sits well below Irish average for this age — verify service history and obtain independent inspection to confirm condition.
• Electrical gremlins (infotainment, battery drain, coding faults) are tedious to diagnose; have a pre-purchase scan done by a BMW specialist, not a generalist.
• Solid used market value for a 3 Series — price range reflects demand; check how many previous owners and whether major work has been done.
