CarHunch is tracking 129 2020 Mercedes Benz Glc 220 D 4m Amg Line Prem A vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.

This 2020 GLC 220D is struggling badly in the MOT arena: a 47.7% first-time pass rate is nearly half the UK average of 80%, which raises serious questions about build quality or how these engines are holding up even at relatively low mileage. The good news is that dangerous defects are running at zero percent, so failures are irritating rather than safety-critical.

At 43,690 miles average, these cars are still young and lightly used, yet the failure rate suggests something systemic rather than wear-and-tear—this points to specific design or manufacturing issues rather than poor owner maintenance. Before buying one, get a pre-purchase inspection focused on engine management systems and emissions equipment, since that's where early-life diesel issues typically hide on Mercedes models.

What to check before buying a 2020 Mercedes Benz Glc 220 D 4m Amg Line Prem A

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
