Is your BMW 5 Series (G30) showing signs of transmission fluid leak? If so, you’re experiencing a common issue that can significantly affect vehicle performance. Given the complexities of the B58 (3.0L I6) engine, any fluid leak can lead to severe complications if left untreated. Transmission fluid leaks, in-particular, can cause troubling shifts, gear slipping, and, worst-case scenario, complete transmission failure.

Common Causes of Transmission Fluid Leak

The transmission fluid leak in your BMW 5 Series (G30) (2017-present) can be caused by a variety of factors. Mechanical issues such as defective seals or gaskets, cracked casing, or a damaged fluid line can lead to leakage. Even electrical issues like malfunctioning solenoid controls or failing sensors can cause abnormal transmission response, leading to leakage. Further, software-related issues cannot be ruled out, as out-of-date software may cause irregular transmission behaviour causing additional strain on physical components.

Solutions to Address Transmission Fluid Leaks

The complexity of modern automotive technology, like that in your BMW B58 engine, necessitates professional diagnostics. An expert diagnosis can properly identify whether the issue is mechanical (seals, casing, fluid line), electrical (sensor or solenoid), or software-related, allowing for targeted solutions to be administered.

Physical issues may require part replacements. This might mean changing seals, gaskets, fluid lines, or even the transmission casing. An electrical problem might require cleaning, repair, or even replacement of the affected components. Out-of-date software, on the other hand, might need a software update, which will correct irregular transmission behavior.
