E&P Caravan Main Control Unit (Brain) 4100056 – OEM Replacement

Product Description

The E&P Hydraulics Main Control Unit (Brain) is the central electronic module used in E&P caravan levelling systems. It controls the hydraulic pump, solenoid valves, pressure switch, and all system safety logic.

This is a genuine E&P/AL‑KO OEM replacement part, designed to restore full functionality to caravans fitted with the E&P LevelC hydraulic levelling system.

If your levelling system is showing faults such as legs not responding, pump not activating, or calibration errors, replacing the Brain is often the correct fix.

Key Features

• Genuine E&P / AL‑KO OEM component
• Controls pump motor, valves, pressure switch, and system logic
• Stores zero‑point calibration
• Plug‑and‑play replacement using existing Deutsch connectors
• No laptop, software, or programming tools required
• Designed for safe, reliable operation in all weather conditions

Is This Unit Plug‑and‑Play?

Yes. The Brain 4100056 is a direct plug‑and‑play replacement for any caravan already fitted with an E&P LevelC system.

• All connectors match the original loom
• Firmware is pre‑loaded
• System auto‑detects pump, valves, and sensors
• No computer or diagnostic software is required

Do You Need a Computer to Install or Calibrate It?

No — never. E&P systems do not require a laptop or external software.

All setup is done through the standard E&P control panel.

Zero‑Point Calibration (Required After Replacement)

After fitting the new Brain:

1. Park the caravan on level ground
2. Manually level using the control panel
3. Hold the AUTO button for ~10 seconds
4. The Brain stores the new zero point

This is the only calibration required.
