Fendt 720 Vario Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has been detected that requires immediate engine shutdown and investigation on your Fendt 720 Vario. | Stop the engine safely and consult the Variotronic terminal for the specific fault code. | |
| Master Caution | AMBER | A non-critical system fault or reminder is active on your Fendt 720 Vario; check the terminal for details. | Review the warning list on the terminal and address the issue at the earliest convenience. | |
| Check Engine (MIL) | AMBER | The engine control unit has detected a fault in the emissions or fuel system specific to your Fendt 720 Vario's AGCO Power engine. | Have the engine diagnosed by a certified Fendt dealer using the diagnostic tool. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe operating level; this can cause severe damage to your 720 Vario's engine if ignored. | Stop the engine immediately and check oil level; if fine, contact service. | |
| Battery / Charging | RED | The charging system is not functioning, and the battery is discharging; your 720 Vario may stall or fail to restart. | Check alternator belt and connections; if lit while running, have the charging system tested. | |
| Coolant Temperature | RED | Engine coolant temperature is critically high; continued operation of your Fendt 720 Vario could cause overheating and damage. | Stop the engine and allow it to cool; check coolant level and fan operation. | |
| Transmission Temp | RED | The Vario CVT transmission fluid temperature has exceeded safe limits, risking transmission damage in your 720 Vario. | Reduce engine load and stop if possible; allow transmission to cool before resuming work. | |
| Parking Brake | AMBER | The parking brake is engaged on your Fendt 720 Vario; this light may also indicate a fault in the brake system. | Release the parking brake before moving; if light persists, check brake pressure or sensor. | |
| DPF / Regeneration | AMBER | The diesel particulate filter is requesting regeneration; your 720 Vario's engine needs to run at high load to clean the filter. | Drive at high engine speed and load for about 20 minutes or perform stationary regen via the terminal. | |
| DEF / AdBlue | AMBER | The AdBlue tank is low or the SCR system has detected a fault; your 720 Vario's emissions system will limit performance if ignored. | Top up AdBlue with quality fluid; if fault persists, have the SCR system inspected. | |
| Water in Fuel | AMBER | Water has been detected in the fuel filter/water separator of your Fendt 720 Vario, which can cause injection system damage. | Drain the water separator immediately; if light stays on, replace the fuel filter. | |
| Low Fuel | AMBER | The fuel level is low; your 720 Vario has about 10% of diesel remaining. | Refuel as soon as possible to avoid air entering the fuel system. | |
| High Beam | BLUE | High beam headlights are activated on your Fendt 720 Vario. | Switch to low beam when oncoming traffic or working near others. | |
| Hydraulic System | RED | A fault in the hydraulic system has been detected; your 720 Vario's implements may lose function. | Stop work and check hydraulic oil level; if ok, contact service. | |
| PTO Engaged | GREEN | The power take-off is engaged and rotating on your Fendt 720 Vario. | Disengage PTO before stopping the engine or when not needed. | |
| Differential Lock | AMBER | The differential lock is engaged on your 720 Vario; avoid turning on hard surfaces. | Disengage differential lock for normal driving to prevent tire wear. | |
| Trailer | GREEN | A trailer is electrically connected and being recognized by your Fendt 720 Vario. | Ensure trailer brakes and lights are functional before moving. | |
| Work Lights | GREEN | The work lights are active on your 720 Vario, improving visibility for field operations. | Switch off work lights when on public roads to avoid blinding others. | |
| Beacon / Rotating Light | GREEN | The warning beacon is active on your Fendt 720 Vario, indicating slow-moving vehicle. | Keep beacon on when operating on public roads as required by law. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Low engine oil level
- Faulty oil pressure sensor
- Worn oil pump or blocked oil passages
What to do
Stop the Fendt 720 Vario immediately, check the oil level on the dipstick, and refill if low. If level is fine, have the oil pressure tested by a Fendt dealer to avoid severe engine damage.
Overheated Coolant
Common causes
- Low coolant level
- Clogged radiator or cooling fins
- Faulty thermostat or water pump
What to do
Stop the engine and allow it to cool on your 720 Vario. Check coolant reservoir and add the correct mixture if low. Clean the radiator screens of debris; if problem persists, inspect the water pump and thermostat.
DEF/AdBlue System Fault
Common causes
- Low AdBlue level
- Contaminated or degraded AdBlue fluid
- Faulty SCR injector or NOx sensor
What to do
Top up with fresh, certified AdBlue. If warning persists, the SCR system may need regeneration or component replacement by a Fendt technician; the 720 Vario will enter reduced power mode if ignored.
DPF Regeneration Required
Common causes
- Extended idling or low-load operation
- Clogged diesel particulate filter
- Faulty exhaust temperature sensors
What to do
Operate the Fendt 720 Vario at high engine speed and load (e.g., plowing with PTO-driven implement) for 20-30 minutes. If light remains, perform a stationary regeneration via the terminal; if still fails, visit a dealer.
Transmission Overheating
Common causes
- Heavy draft work in hot conditions
- Low transmission oil level
- Clogged transmission oil cooler
What to do
Reduce load and allow the Vario transmission to cool; check transmission oil level through the sight glass. Clean the oil cooler fins with compressed air. Avoid continuous heavy towing in high ambient temperatures.
Frequently Asked Questions
Why does my Fendt 720 Vario show a DPF regeneration light after only a few hours?
Frequent light-duty or idling operation causes soot buildup. The 720 Vario's DPF requires periodic high-load regeneration; if it occurs too often, consider using a higher gear or increasing engine load during tasks.
What does the 'Master Warning' light mean and what should I do?
The Master Warning indicates a critical fault that demands immediate engine stop. On the 720 Vario, turn off the engine and consult the Variotronic display for the specific fault code before restarting.
How do I know if my AdBlue tank is low on the Fendt 720 Vario?
An amber DEF warning appears on the cluster; additionally, the display shows remaining AdBlue range. The tank holds about 30 liters; refill when below 10% to avoid performance deration.
Can I drive my Fendt 720 Vario with the engine oil pressure light on?
No. The red oil pressure light means oil pressure is dangerously low. Continuing to operate will cause catastrophic engine damage. Stop immediately and check oil level.
How often should the fuel/water separator be drained on the 720 Vario?
Check daily or when the 'Water in Fuel' light appears. Drain the separator by turning the valve at the bottom until clean fuel runs out. Replace the filter annually or every 500 hours.
What does the transmission temperature warning indicate?
It means the Vario CVT oil is too hot, often from heavy pulling or high ambient temps. Reduce load and let the tractor idle to cool; if persistent, clean the oil cooler and verify oil level.
