The Selective Catalytic Reduction (SCR) system on your diesel BMW reduces exhaust emissions by injecting diesel exhaust fluid (a mixture of urea and water) into the exhaust to neutralize pollutants. If your tank is empty or your metering valve has failed, your car will not start until the problem is remedied. Replace yours with an OEM Bosch to restore your emissions system and get your car back on the road! Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products. As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

The SCR reservoir heater, found in the DEF active tank, is a frequently failing component that can lead to emissions-related DTCs. When it fails, replacing the entire tank assembly is often necessary, which can be expensive if using Genuine parts.

Fortunately, Bosch offers a high-quality replacement heater and tank assembly, ensuring a seamless and reliable replacement process. Opting for Bosch means choosing a cost-effective repair solution that promises durability and longevity.

For a hassle-free replacement of your SCR heater, trust Bosch to deliver lasting performance.
