Welcome to our latest blog, BMW owners! Fault codes may seem perplexing, but they are in fact your vehicle’s way of speaking to you, informing you of any potential issues that need to be addressed. Today, we delve into fault code P171E, a noteworthy one because it relates to your BMW’s sophisticated Transmission Control Module (TCM).

Understanding Fault Code P171E

Fault code P171E, also known as “Internal Transmission Control Module Watchdog Plausibility Error,” is particularly important. The TCM is essentially the brain of your BMW’s transmission. It manages tasks such as gear shifting and clutch engagement, influencing the overall performance, fuel efficiency, and longevity of your vehicle. A plausibility error indicates that the TCM is getting conflicting or implausible information, which may impact the module’s behavior and your car’s performance.

Symptoms of Fault Code P171E

If this fault code appears, you may notice:

  • Reduced fuel economy
  • Incorrect or rough gear shifts
  • Transmission slipping or lagging
  • The appearance of a “Check Engine” or “Transmission Warning” light on your dash

Common Causes

Causes of fault code P171E may include:

  • Corroded, broken, or loose connection in the TCM
  • Faulty or aging TCM unit
  • Software needing an update
