The Audi A5 is sleek, powerful, and one of the best performers on the road. But even the best have their quirks. Audi A5 owners—especially those with models from 2009 to 2020—know the frustrations that come with engine problems. Oil leaks, turbocharger failures, and timing chain issues? Yeah, they’re real, and they happen more often than you’d think. At Cowden Automotive in San Francisco, we know these problems inside and out, and we’re here to keep your A5 performing at its peak.
1. Turbocharger Trouble: Boost That Fails
If you’ve driven an Audi A5 from 2013 to 2019, chances are you’ve felt the turbo boost give out. The A5’s turbocharged engines are fantastic—until they’re not. The most common culprit? Carbon buildup. Or maybe it’s oil contamination. Either way, when that boost isn’t boosting, you’ll know it. Whining noise? Check. Black smoke from the exhaust? Yep. It’s frustrating. But more importantly, it’s fixable.
Here’s how we handle it: We’ll tear down the system, clean it up, and install new turbo components if needed. We’ll also give you the lowdown on how to prevent this from happening again—regular oil changes with top-tier synthetic oil keep that turbo purring. Simple, right?
What would your Audi be without that boost?
2. Timing Chain Tensioner: A Ticking Time Bomb
2009-2014 Audi A5 owners, listen up. Your timing chain tensioner could be on the edge of failure. Think of it as the part that keeps your engine’s most vital components in sync. When it fails—and it often does—you’re looking at a major headache. That rattling noise you hear at startup? That’s the first sign. Ignore it, and you could end up with misfires or worse, catastrophic engine damage.
What’s the fix? We at Cowden Automotive replace the faulty tensioner and often the entire timing chain system. The key is catching it early. If that rattle gets too loud, the damage could already be done. So, don’t wait. Trust us, you don’t want to know what happens if you do.
Have you heard your engine rattle?
3. Oil Leaks: The Silent Destroyer
Audi A5 models, particularly from 2009 to 2016, are infamous for their oil leaks. This isn’t just a small drip. We’re talking about oil seeping from valve cover gaskets, the oil pan, or even the timing chain cover. It’s sneaky. One day, you notice a small puddle under your car. The next day, you’re running low on oil and risking severe engine damage. That burning smell? Not a good sign.
Our solution: We track down the leak, replace the faulty gaskets, and clean up the mess. With our expert touch at Cowden Automotive, you’ll be back on the road without a second thought.

4. Water Pump Woes: Keep It Cool
If your Audi A5 was built between 2010 and 2018, you’re probably aware of the infamous water pump issue. It’s a small part with a huge responsibility—keeping your engine cool. But when it fails? Overheating. And if you keep driving an overheating engine, well, you’re asking for trouble. You’ll see coolant leaks or, worse, that dreaded temperature gauge spiking.
Our solution is simple but crucial: We replace the faulty water pump with an OEM part and test the entire cooling system to make sure everything is working properly. It’s a must-fix if you want to avoid bigger problems down the road.

5. Carbon Buildup: Power’s Worst Enemy
Direct injection engines in the Audi A5 are known for one thing—carbon buildup. Models from 2008 to 2020 are particularly prone to this. When carbon builds up on your intake valves, the engine can’t breathe properly. This leads to misfires, poor acceleration, and decreased fuel efficiency. In short, your car feels sluggish.
The fix? Walnut blasting. Yes, you heard that right. It’s the most effective way to clean carbon deposits from your intake valves, restoring your engine’s performance. At Cowden Automotive, we use specialized equipment to blast away the carbon and get your engine running like new.
