Volkswagen Crafter MD1CS104 AdBlue Level / Quality Sensor Emulator – Your Protection Against Low-Quality AdBlue!
Unfortunately, it is not always possible to find high-purity, standards-compliant AdBlue in every region. Especially in remote areas or markets where local production is common, mixtures with low urea concentration or non-standard AdBlue can lead to serious faults and noticeable engine performance losses.

Volkswagen Crafter MD1CS104 AdBlue Level / Quality Sensor Emulator is an innovative solution developed to completely eliminate this problem. The device electronically simulates AdBlue quality, allowing the system to always detect ideal operating conditions. As a result, even when low-quality AdBlue is used, the vehicle continues to operate without warnings or performance reduction.

The device operates in two different modes, eliminating both low-quality AdBlue–related issues and sensor-related faults. Even if the sensor is completely defective, this emulator safely simulates both AdBlue quality and level for the system.

Key Features:

• Full compatibility with low-quality or non-standard AdBlue
• Reliable operation even in case of sensor failures
• Prevents engine warning light, SCR warnings, and NOx-related faults
• Ideal for users who cannot access high-quality AdBlue in challenging regions
• Easy installation, maintenance-free

The AdBlue Quality Emulator takes over all quality-related checks within the vehicle’s AdBlue system and electronically reports that the system is operating without issues. Whether you are using low-quality AdBlue or have a faulty sensor, your vehicle continues to operate safely without entering emission-related fault mode.
