BMW 3 Series2018

• Timing chain rattle and carbon buildup plague these petrol engines—budget €800–1,200 for tensioner, walnut blasting €400–800 before buying.
• Median price €18,475 is fair for the segment; check mileage sits within 96k–176k km range, as 112k km median suggests heavy daily use.
• Electrical gremlins (infotainment drop-outs, battery drain) are common—have a pre-purchase diagnostic run to catch hidden module faults early.
• Inspect cold-start behaviour closely: any rattle or hesitation indicates imminent carbon/chain work; negotiate repair costs into offer.
• 3 recalls on file; confirm all completed with dealer history before exchange—outstanding recalls can delay NCT or registration.
