Frequently Asked Questions

What does it mean when the check engine light comes on in a 2016 BMW 4 Series Gran Coupe?

  • It signals the engine control unit detected a fault — anything from emissions components to ignition or fuel issues. Our certified BMW techs at Herb Chambers BMW Certified Preowned Medford use OEM-level diagnostics to pinpoint the cause quickly.
  • We provide a clear estimate and explain immediate and long-term savings of fixing issues early, often costing less here than at independent shops while delivering higher service standards.
  • Repairs covered under warranty must be completed at a certified dealership to retain coverage; ask about our service financing if you want to schedule service now and pay later.

How long does a check engine light service take?

  • Most diagnostics are completed the same day; simple fixes can be finished in a single visit. Complex repairs take longer, and we’ll provide a precise timeline up front.
  • Our efficient workflow, full parts inventory, and factory diagnostic systems keep turnaround fast and reliable, saving you time and money compared with extended downtime.
  • Book a convenient time through our online scheduler to minimize waiting: schedule service.

  • Pricing varies by issue severity. We’ll provide an upfront estimate and show how prompt repairs avoid larger future expenses.

What is the most common reason for check engine light on a 2016 BMW 4 Series Gran Coupe?

  • Common causes include oxygen sensors, catalytic converter/emissions faults, ignition coil or spark plug problems, and loose gas caps. Each can impair fuel economy and performance if left uncorrected.
  • Our certified technicians use factory diagnostics to identify root causes, then recommend OEM repairs that protect warranty and resale value.
  • We emphasize long-term savings—addressing issues early reduces repair costs over the vehicle’s life and preserves driving enjoyment.

What is the first thing to check when the check engine light comes on?

  • Check for simple items first, such as a loose or missing gas cap, which can trigger emissions codes. If the light persists or flashes, stop driving and contact us immediately.
  • For accurate, safe results, bring the vehicle to Herb Chambers BMW Certified Preowned Medford where our diagnostics and certified staff ensure proper repairs and warranty compliance.

2016 BMW 4 Series Gran Coupe Check Engine Light Codes

The 2016 BMW 4 Series Gran Coupe is sophisticated, and its diagnostic trouble codes (DTCs) can range from simple emissions faults (P0420 — catalytic efficiency) to ignition misfires (P0300 series) or oxygen sensor failures (P0130–P0167). In Medford, Herb Chambers BMW Certified Preowned Medford uses BMW Group diagnostic tools to translate these codes into clear repair plans. For example, an oxygen sensor code left unaddressed can reduce fuel economy and damage the catalytic converter — potentially turning a modest $200–$400 repair into a much costlier $1,000+ replacement. A misfire left unresolved increases wear on the catalytic converter and drivability issues; addressing spark plugs or coils early typically costs far less than downstream repairs. By choosing our certified center you get accurate code interpretation, OEM parts, and a recommended service timeline that emphasizes immediate and long-term savings. We document needed repairs, explain alternatives, and honor warranty requirements. To minimize downtime and protect resale value, schedule service or check our current service specials before you arrive.

2016 BMW 4 Series Gran Coupe Check Engine Light Reset

Resetting the check engine light on a 2016 BMW 4 Series Gran Coupe is only a temporary fix unless the underlying fault has been resolved. Our technicians use OEM-level tools to clear codes only after verifying repairs and confirming systems are operating within specifications. Independent scanners or quick resets can erase fault history and mask intermittent issues, increasing the risk of long-term damage and voided warranty coverage. At Herb Chambers BMW Certified Preowned Medford we emphasize transparency: we show you stored codes, explain root causes, and provide a written estimate before any work begins. Using OEM parts and factory diagnostic procedures ensures the reset is permanent because the fault is corrected, not hidden. We also offer service financing to make necessary maintenance affordable—get repairs now and pay over time. For an honest appraisal and professional reset handled to BMW specifications, schedule service today and explore our service specials to save on needed maintenance.

Check Engine Light Flashing

A flashing check engine light on a 2016 BMW 4 Series Gran Coupe indicates a severe condition such as a persistent misfire that can quickly damage the catalytic converter and other systems. This is a higher priority than a steady light and requires immediate attention — do not continue driving if the light is flashing. At Herb Chambers BMW Certified Preowned Medford we prioritize flashing-light vehicles for rapid diagnosis to limit damage and expense. Our factory-trained technicians will perform a thorough inspection, use BMW diagnostic modules, and provide a clear repair plan and estimate. We frequently run promotions and maintain service specials to lower your cost of ownership; visit our service specials page for current offers. Because warranty-covered repairs must be completed at a certified dealership, choosing our service center protects both your warranty and vehicle longevity.
