Vehicle Diagnostics in Englewood, CO

Check Engine Light On?

A flashing check engine light is typically indicative of a serious problem affecting your vehicle’s ignition, fuel or emission systems. If your check engine light is on or flashing, it’s time to come to AutoImports of Denver for a car diagnostic. Our auto service professionals will investigate the check engine code error and troubleshoot the problem. If you delay a car diagnostic or necessary engine repairs, the problems and costs can quickly escalate.

When you bring your car to AutoImports of Denver our experienced Master Mechanics will perform on-board diagnostics and determine why your check engine light (service engine soon) is on or flashing. While it’s impossible to say exactly why a check engine light is on or flashing without being able to examine the vehicle and perform a car diagnostic, possible causes of a steady or flashing check engine light can include:

  • Failing oxygen sensor
  • A loose gas cap
  • Bad spark plug/ignition coil
  • Bad spark plug wires
  • A problem with your catalytic converter
  • Bad mass air flow sensor
  • Engine vacuum leak
  • EGR valve problem
  • Excessive gas consumption or release of air pollutants

Diagnostic Services in Englewood, CO

The problem you now face is what to do about the check engine light. There are literally thousands of diagnostic trouble codes (DTCs) that the check engine light might refer to. The only way to even get started is to connect a scan tool. Some auto repair shops charge for auto diagnostic services, but some places, such as auto parts stores, offer to scan your vehicle for free. You are probably wondering, “Why should I pay for auto diagnostic service when someone will do it for free?”

Today, it seems that more people are “price shopping” than ever before, but this doesn’t really help anyone. As the saying goes, “You get what you pay for,” and this is especially true in the auto repair field. If you don’t pay for auto diagnostic service, such as offered by various autoparts stores, what exactly are you getting?

Do You Really Want To “Chance” So Called “Free” Auto Diagnostic Services?

The truth is, at best, you’ll get a printout of the DTC and a “guess” as to what the problem might be. It’s an autoparts store, after all, and their business is selling parts, not necessarily fixing cars. At worst, you might buy parts that don’t end up fixing the problem. In the end, you got a “free” auto diagnostic check, but you wasted time and money on unnecessary parts. Where’s the value in that?

On the other hand, if you pay for auto diagnostic service (the average is between $150-$250) where’s the value in that? Most auto repair shops employ ASE-Certified technicians, who spend thousands of hours in training and working on cars every day, and also maintain thousands of dollars in modern auto diagnostic and repair tools. If you have a check engine light, trained technicians use state-of-the-art diagnostic tools to give you an accurate diagnosis.

Summer in Colorado means open roads, mountain passes, and perfect weather for putting real miles on your Porsche. Whether you're planning a canyon run through Clear Creek, a track day, or just enjoying top-down cruises around Denver, your Porsche needs to be ready for the heat, altitude, and demanding driving that summer brings. At AutoImports of Denver, we specialize in Porsche repair and maintenance — and every summer, we see the same handful of issues catch owners off guard. Here's what our Porsche specialists recommend before you put serious mileage on your car this season. Why Summer Prep Matters for Your Porsche Colorado's combination of high altitude, intense UV exposure, and big temperature swings between morning and afternoon puts unique stress on a Porsche's cooling system, tires, and fluids. A car that ran perfectly all winter can develop problems fast once temperatures climb and you start driving harder and longer. A proactive Porsche service visit now can save you from a breakdown on I-70 during peak mountain season — or worse, expensive engine or transmission damage from overheating. Our Porsche Summer Service Checklist Cooling System Inspection Porsche engines run hot, and a failing water pump, thermostat, or coolant leak is far more likely to cause problems in 90-degree heat. We check coolant condition, hose integrity, and radiator performance as part of every summer service. Air Conditioning Performance Nothing ruins a summer drive faster than AC that can't keep up. We test refrigerant levels, compressor function, and cabin airflow — especially important on Cayenne, Macan, and Panamera models with more complex climate systems. Tire Condition and Alignment Summer means more spirited driving, and your tires take the brunt of it. We inspect tread wear, check for sidewall damage, and verify alignment — critical for handling on both highway trips and mountain curves. Brake System Check Between mountain descents and everyday Denver traffic, your brakes work hard. We inspect pad thickness, rotor condition, and brake fluid quality, since fluid degrades over time and affects stopping performance in high-heat conditions. Fluid Levels and Battery Health Oil, transmission fluid, and battery performance all shift with temperature. We handle full fluid checks and battery load testing so nothing catches you off guard on a hot afternoon. PDK and Drivetrain Inspection For 911, Boxster, and Cayman owners running PDK transmissions, we check for proper shifting behavior and fluid condition — small issues are much easier (and cheaper) to catch early. Why Choose an Independent Porsche Specialist As a trusted independent Porsche service shop, AutoImports of Denver offers factory-trained technicians, genuine OEM parts, and the same level of expertise you'd expect from the dealership — without the dealership price tag or wait times. We work on every model, from classic 911s to modern Taycan EVs, and we treat every car with the attention it deserves. Book Your Porsche Summer Service Today Don't wait until you're stranded on a mountain pass. Schedule your Porsche's summer inspection and maintenance with AutoImports of Denver today, and hit the road with confidence all season long. Contact AutoImports of Denver to schedule your Porsche summer service appointment.
