Common Repairs on the 5th Generation Audi A4 B9

The Audi A4 B9, introduced in 2015 and in production today, retains the brand's signature design language, featuring a refined and sophisticated exterior with distinctive headlights and a wider stance. While delivering a harmonious mix of style, performance and modern amenities this compact luxury sedan still has some common issues to be on the lookout for.

Leaking Engine Mounts: On occasion the engine mounts may start to leak hydraulic fluid. If you notice engine vibrations, misalignment or a shaky start, this may be the issue.

Water Pump Failure: The water pump in the B9 is prone to failing early and may cause engine damage. This could be due to wear and tear, lack of coolant or defective parts. To be safe, take your A4 to an experienced Audi repair shop for diagnostics and repair.

Thermostat Housing Leak: Quite common, the thermostat housing may begin to leak. If so, you’ll notice your engine may overheat, erratic temperature readings and the low coolant indicator illuminated. You may need a replacement, so we recommend bringing your B9 to a specialized Audi repair technician.

Oil Seepage/Leaks: Some B9 owners have reported noticing oil leaks and seepage from various engine components.

If you are experiencing any of these problems, a trip to your local German auto import specialist is the best way to address the issue. Their experience and expertise will ensure your repairs are handled as quickly as possible.
