Land Rover Jaguar B13c2-49 Portable Link

When diagnosing the vehicle via specialized software, the humidity or windshield temperature field will show a fixed value, such as a constant 0% or -40°C . Common Root Causes

Corroded, damaged, or broken wiring in the LIN (Local Interconnect Network) communication circuit, power, or ground.

The sensor is located behind the interior rearview mirror, attached to the windshield, often under a plastic cover.

The diagnostic trouble code (DTC) on a Jaguar or Land Rover vehicle indicates an internal electronic failure of the windshield misting sensor (also referred to as the humidity sensor). This sensor is located behind the rearview mirror cover and continuously monitors cabin humidity and interior temperature to prevent the glass from fogging. When it experiences an internal hardware failure, it ceases communicating correct information to the automatic climate control module, resulting in a persistent "Permanent" fault status. What is the Windshield Misting Sensor?

For most owners, replacing the internal fan is a simple, low-cost fix that restores full function. If you lack soldering skills, a reputable independent JLR specialist can perform the repair for under $350 – far less than the $2,000+ dealer replacement.

Jaguar and Land Rover often share this part. You can sometimes find the Jaguar-branded version at a lower price even though they are identical. When diagnosing the vehicle via specialized software, the

Unlike minor communication hiccups, code B13C2-49 typically refuses to clear or reappears immediately after cycling the ignition. Affected Vehicles and Part Numbers

In certain JLR models (especially the Range Rover Evoque and Discovery Sport), a corrupted sensor can cause the climate control interface to temporarily freeze, lag, or cycle rapidly upon engine startup.

This is the most common fix. The genuine part number for many Land Rover models (like the Range Rover L405 or Evoque) is LR058011 . If you are seeing this code, the "useful

According to user reports, the most effective fix for this error is replacing the sensor. 1. Replace the Windshield Misting Sensor

While the sub-code specifically targets an internal component failure, several physical factors can trigger or mimic this code on models like the Range Rover L405, Range Rover Sport L494, Discovery 4/5, and Jaguar F-Pace:
