Est. Repair Cost: £1,000–£2,500
Warning Signs:

Radar failure warnings, Active cruise control disabled, Visible deep cracks

What to Inspect:
  • Inspect the grille under good lighting
  • Test adaptive cruise control on the test drive

Electrochromic Panoramic Glass Roof Dimming Inconsistency

ModerateBodywork & Rust

The standard electrochromic panoramic glass roof uses Polymer Dispersed Liquid Crystals (PDLC) to switch from transparent to opaque. Delamination or controller failure leaves patchy transparent blotches.

Est. Repair Cost: £0 (Warranty / £1,500–£3,500)
Warning Signs:

Uneven cloudiness across panoramic roof, Roof fails to turn opaque on button press, Flickering during transition

What to Inspect:
  • Press roof dimming toggle overhead and inspect entire roof surface from front to rear
  • Confirm uniform shading across all glass segments

Buying Tips for 2024 BMW iX (I20)

  • Test the complex iDrive 8 system and the 'Shy Tech' interior buttons (integrated into the wood trim) for responsiveness and software lag.
  • Check the electrochromic panoramic glass roof (which turns opaque at the touch of a button) to ensure it transitions evenly without patchy spots.
  • Inspect the carbon-fibre reinforced plastic (CFRP) door shuts for any signs of damage or cracking, as structural repairs are incredibly specialized.
  • Verify the charging flap operates correctly and the car achieves its claimed rapid charging speeds without throwing errors.
  • Listen to the air suspension over rough roads; the iX is very heavy, so worn bushes or failing struts will cause noticeable knocking.
  • Ensure the self-healing polyurethane front grille isn't deeply gouged, as the embedded radar sensors require a clear line of sight to function.
