Frequently Asked Questions
Are clogs with the Audi A4 Quattro catalytic converter normal?
Yes. Clogs happen because the catalytic converter builds up chemical matter after repeated and long-term use--this is perfectly normal, as long as the unit remains intact. The common sign that will indicate clogs is when the Audi A4 Quattro fails to accelerate right away when the gas pedal is stepped on. Worse cases of clog may totally render the car dead. Although a replacement may not be necessary if the unit is in good physical condition. Clean the old part first and test it out before finally deciding whether or not a replacement is needed.
Are there certain substances that need the Audi A4 Quattro catalytic converter to be prevented from?
Other than lead, there is nothing else to worry about. Lead encapsulates the internal system of the converter and prevents it from treating the exhaust. All vehicles with a catalytic converter should only fill up on unleaded petrol to avoid poisoning the system.
Can the Audi A4 Quattro catalytic converter be installed without a mechanic?
Installing it may be a bit difficult especially without sufficient mechanical experience. Several parts need to be detached before the catalytic converter can be moved; reinstalling those parts again in their proper places can be tricky. And before anyone goes out to buy a catalytic converter, remember that it is absolutely illegal anywhere in the US to sell and use a second-hand unit. Again, smog regulations are strict, and refurbished converters will not pass the assessment.
Can the Audi A4 Quattro run with a catalytic converter uninstalled?
Yes, it can. But no exhaust gas conversion will take place. The emission will produce a thick, black smoke, and the federal government has stringent laws on environmental pollution. It prohibits all vehicles to run without a converter. Hence, the constant emission test required every registration.
