A lit warning light on your BMW X1’s dashboard – a feeling many drivers know and dread. Often, this is an error message, further specified by a so-called error code. But what exactly does this code mean, and how can you fix the problems on your X1 yourself? In this article, we explain everything you need to know about BMW X1 diagnosis and provide helpful tips for troubleshooting.
What is a BMW X1 Error Code?
Imagine your BMW X1 as a complex computer on four wheels. Numerous sensors and control units constantly monitor the vehicle’s condition and report irregularities to the vehicle electronics. If a problem occurs, an error code is stored in the vehicle’s fault memory. This code usually consists of a letter and four numbers, e.g., “P0171”.
