Audi makes great luxury cars. We’re big fans. But as you’ve seen from our other blog posts, no automobile is perfect. Every make, model and year have their issues to contend with. That’s what we’re here for. At JL Motorworks, we know and love Audis and the owners who drive them. If something strange is happening with your Audi, bring it in for a quick and accurate diagnosis today. Here are the top five Audi problems we see that require repairs:
In the meantime, you can prevent Audi problems from happening by taking your car to your mechanic for regular maintenance, oil changes, fluid top-offs, air filter replacement, tire pressure checks, tire rotations, brake inspections, and more.
Here are the top five Audi problems we see that may require repairs.
Top 5 Audi Problems & Repairs
1. Ignition Coil
If your Audi’s check engine light is on and it’s running rough, you may have an ignition coil failure. The ignition coil is the part of the ignition system responsible for generating the engine spark that ignites the engine’s air-fuel mixture. Ignition coil failure is the main reason behind engine misfires. You may also experience a loss of power when accelerating.
2. Catalytic Converter
The catalytic converter is an emissions control device that creates a chemical reaction in which toxic gases and pollutants are “converted” to produce less harmful, or even inert matter. Catalytic converters usually fail due to carbon buildup that solidifies and clogs the exhaust flow. Be careful, though: that buildup is being caused by some issue that you need to find. Simply replacing the catalytic converter is a temporary solution — it won’t fix the root problem. Get your Audi to your trusted mechanic for a proper diagnosis.
3. Exhaust Gas Recirculation
Exhaust gas recirculation (EGR) is a nitrogen oxide emissions reduction technique that recirculates a portion of the exhaust gas back into the engine cylinders. It’s also the system that lowers temperatures in the combustion chamber. When the EGR fails, the result is carbon buildup (see above), which clogs the exhaust flow.
Symptoms of EGR failure include the check engine light coming on, a rough idle, and decreased power and acceleration.
Exhaust leaks from failed exhaust systems are also common problems with Audis. Symptoms include decreased fuel economy, vibrating gas pedal during acceleration, and a noisy/rumbling engine.
4. Oil Leak
Audi oil leaks are usually due to a faulty valve cover gasket or camshaft tensioner (or tensioner gasket seals). Once you determine the culprit, it’s a pretty easy fix to replace the part.
5. Audi A4
The A4 is the longest running model manufactured by Audi so naturally, it will show the most problems over time. Typical problems for the Audi A4 include excessive oil usage and engine failure, particularly with the 2002 and 2013 models.
