The BMW 5-Series E39, produced from 1996 to 2003, represents a hallmark of luxury and performance in the midsize sedan category. Understanding the fuse box and relay diagrams of these models is essential for maintaining and troubleshooting their sophisticated electrical systems. This article provides detailed insights into the locations, functions, and significance of these components, offering clarity on the BMW 5-Series E39’s electrical architecture.
(1996-2003) BMW 5-Series (E39) fuse box and relay with Diagram
WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
