Even though Wilmington winters are relatively mild, chilly mornings can still be tough on your European car. From sluggish starts to frosty windshields and underperforming heaters, cold weather can expose small issues that quickly become major problems. Whether you drive a BMW, Audi, Mercedes-Benz, or Mini, taking the time to winterize your vehicle can make those cold mornings far more manageable — and help you avoid costly repairs later on.
Here’s how to get your European vehicle ready for winter, including a few DIY tips and when it’s best to call in the experts at Performance Auto Specialists.
1. Give Your Battery Some Attention
Cold weather and weak batteries don’t mix. When the temperature drops, your car’s battery loses a significant amount of cranking power — sometimes up to 30%. If your vehicle already struggles to start, winter will only make it worse.
DIY Tip:
Check your battery terminals for corrosion (it will be a white or greenish buildup). If you see any, carefully clean them using a mixture of baking soda and water with a small brush.
Make sure the connections are tight and secure.
If you have a voltmeter, test the battery’s voltage. A healthy, fully charged battery should read around 12.6 volts.
When to Call the Experts:
European vehicles often use advanced electrical systems and AGM or gel batteries that require specialized testing equipment. If your car is slow to start or you notice dimming lights, our ASE-certified technicians can perform a comprehensive battery load test and charging system inspection. We’ll make sure your alternator, starter, and battery are all working together — and replace components using OEM parts backed by our 24-month/24,000-mile warranty.
2. Choose the Right Tires for the Season
European performance vehicles deliver exceptional handling precision, but only when equipped with suitable tires. When temperatures decline, tire compounds become rigid, compromising both grip and stopping performance.
DIY Tip:
Assess tread depth with the penny method: place a penny into the groove with Lincoln’s head inverted—if the entire head remains visible, replacement is necessary.
Monitor tire pressure regularly. Cold weather reduces pressure by approximately 1 PSI per 10°F temperature drop. The recommended PSI specification appears on the placard inside your driver’s door.
When to Call the Experts:
Uneven tread wear, unusual vibrations, or diminished traction indicate it’s time for expert evaluation. Correct wheel alignment enhances traction while preventing accelerated wear to suspension and steering systems.
3. Don’t Neglect Your Heating and Defrosting Systems
A well-functioning heating system does more than keep you warm. It’s essential for visibility and safety while driving. If your defroster isn’t working, you may have a more serious issue than just an uncomfortable ride.
DIY Tip:
Replace your cabin air filter before winter. A clogged filter can reduce airflow and make your heater less effective.
Make sure your vents are open and unobstructed.
Test your defroster early in the season — don’t wait for the first frosty morning to discover it’s not working.
When to Call the Experts:
Heating and defrosting issues often trace back to your vehicle’s coolant system or a failing blower motor. European models like BMW and Audi use intricate climate control systems that require specialized diagnostics. Our technicians use state-of-the-art computer diagnostics to pinpoint problems quickly and restore comfort to your cabin.
If you’re feeling cold air when you expect heat, bring your car in. We’ll check for coolant leaks, thermostat malfunctions, or heater core issues before they turn into expensive repairs.
4. Keep Fluids Fresh and Flowing
Your car’s fluids are its lifeblood, especially in winter. Low or dirty fluids can lead to sluggish performance, corrosion, or even engine damage.
DIY Tip:
Check your coolant level and make sure it’s rated for freezing protection.
Top off your windshield washer fluid with a winter formula that resists freezing.
Make sure your oil is clean and at the right viscosity. Some European cars perform better in cold weather with specific synthetic oils. Check your owner’s manual for recommendations.
When to Call the Experts:
European vehicles require precise fluid specifications, from coolant formulations to transmission oils. Using the wrong type can harm your engine or void warranties. Our technicians use only OEM-approved fluids designed for your make and model, ensuring maximum performance and protection all winter long.
5. Prepare for Frosty Mornings
Even simple preparations can make cold mornings easier:
- Keep an ice scraper and microfiber cloth in your glove box.
- Avoid using hot water to defrost windows; it can cause cracks.
- If your car sits outside overnight, consider using a windshield cover to prevent frost buildup.
- For newer European vehicles equipped with smart key systems, check your owner’s manual for remote-start features or pre-conditioning options that warm the cabin before you even step outside.
