Emission Test - Preparation

For your reference, we have provided a few points on how to best prepare for your emissions test:

• Test early. Testing early allows failing motorists plenty of time to repair their vehicle and receive a passing retest before the registration expires.
• Have your oil changed by your authorized BMW Technician as scheduled.
• Replace your fuel cap securely after filling up. The "Check Engine" light may illuminate as a result of a loose fuel cap. If the "Check Engine" light is illuminated, try tightening the fuel cap until it clicks, then drive the vehicle until the light turns itself off. If it does not turn off, take your BMW to an authorized BMW Technician.
• Keep your tires properly inflated.
• Check belts and hoses for wear.
• If your "Check Engine" or "Service Engine Soon" light is on, your vehicle will need to be checked by an authorized BMW Technician. This light notifies motorists when something in the emission control system fails or begins to deteriorate. Early diagnosis and repair can prevent more costly repairs in the future.
• Keep the sealing surfaces of your fuel cap clean and in good condition.
• 30-day free retest. If you fail your emissions test, you will receive a free retest at Global Imports if you have your BMW repairs done at Global Imports.
• Tickets. Motorists driving with expired tags will most likely receive tickets from local law enforcement.
• Avoid high traffic times and days of the month at other service centers. Have your emissions test done when your BMW is in for service and make it convenient for you!
• Make Global Imports your emission testing center of choice by making an appointment convenient for you. 
• The most common reasons for emission test failures include:
• a malfunction in the components of the vehicle that regulate the fuel/air ratio such as the oxygen sensor and the EGR valve.
• a dirty air filter.
• misfiring spark plugs.
• leaks in the vacuum system.
• a poor-fitting fuel cap.
• A transmission problem is directly related to the emission control system and can trigger the "Check Engine" light. A diagnostic analysis will yield a transmission code that will help identify the component(s) needing repair. Transmission malfunctions can prevent your BMW from running efficiently, increasing emissions above federal certification limits.

Many of these components can be checked and repaired during routine servicing. Follow BMW's recommended maintenance schedule and have your BMW serviced by a certified and trained Technician at Global Imports BMW.
