Fendt 516 Vario Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red stop symbol indicates a critical system failure requiring immediate engine shutdown on your Fendt 516 Vario. | Stop the tractor safely, shut off the engine, and contact your Fendt dealer. | |
| Master Caution | AMBER | Amber caution signals a non-critical fault that needs attention soon on your 516 Vario. | Check the display for additional messages and schedule service promptly. | |
| Check Engine (MIL) | AMBER | This lamp alerts you to an engine management or emission control issue specific to the Fendt 516 Vario’s diesel engine. | Reduce load and have the engine diagnosed by a qualified technician. | |
| Engine Oil Pressure | RED | Low oil pressure detected in the 516 Vario’s engine; internal damage may occur if not addressed. | Stop the engine immediately and check the oil level. | |
| Battery / Charging | RED | The charging system is failing, possibly due to a faulty alternator or belt on your Fendt 516 Vario. | Inspect the alternator belt and connections; if light stays on, have the system checked. | |
| Coolant Temperature | RED | Engine coolant temperature exceeds safe limits on your 516 Vario, risking overheating. | Stop the engine, let it cool, then check coolant level and fan operation. | |
| Transmission Temp | AMBER | Vario transmission oil temperature is high; continuous operation may cause damage to the CVT. | Reduce engine load and allow transmission to cool; if persists, check oil level. | |
| Brake System | RED | A fault in the service brake system compromises stopping ability on the Fendt 516 Vario. | Do not operate; check brake fluid level and consult your dealer. | |
| Parking Brake | RED | Indicates the parking brake is engaged or a malfunction exists in the brake linkage. | Ensure the brake is fully released before moving; if light remains, inspect the switch. | |
| Hydraulic System | AMBER | The hydraulic pump or oil temperature is outside normal range affecting implements on your 516 Vario. | Check hydraulic oil level and temperature; reduce implement load. | |
| PTO Engaged | GREEN | The rear PTO is engaged and rotating, providing power to attached implements. | Disengage PTO before leaving the cab or performing maintenance. | |
| Differential Lock | AMBER | The differential lock is engaged, providing equal traction to both rear wheels on the Fendt 516 Vario. | Disengage on hard surfaces to prevent tire wear and driveline stress. | |
| Work Lights | GREEN | The rear work lights are activated for nighttime field operations. | Turn off when not needed to conserve battery power. | |
| Beacon / Rotating Light | GREEN | The roof-mounted beacon is active, alerting others to your tractor’s presence. | Switch off on public roads if not required by law. | |
| Air Filter | AMBER | The engine air filter is restricted, reducing airflow to the Fendt 516 Vario’s engine. | Replace the air filter element to prevent power loss. | |
| Fuel Filter / Water Separator | AMBER | Water or contamination detected in the fuel filter/water separator system. | Drain water from the separator and replace the fuel filter if necessary. | |
| DPF / Regeneration | AMBER | The diesel particulate filter requires regeneration to clean accumulated soot. | Drive the tractor at higher load to initiate active regeneration or start a parked regen from the display. | |
| DEF / AdBlue | AMBER | AdBlue fluid level is low or quality is poor, affecting emission compliance. | Refill with fresh AdBlue; if light remains, check fluid quality. | |
| Water in Fuel | AMBER | Water has accumulated in the fuel system, which can damage the engine’s injection components. | Drain water from the fuel filter bowl immediately. | |
| Low Fuel | AMBER | Fuel level is critically low; the engine may stall if not refilled. | Refuel as soon as possible to avoid running out in the field. | |
| High Beam | BLUE | The headlights are on high beam for improved visibility. | Dim for oncoming traffic to avoid glare. | |
| Fasten Seat Belt | RED | The driver’s seatbelt is not fastened; safety system is incomplete. | Buckle the seatbelt before operating the tractor. | |
| Glow Plug / Preheat | AMBER | The glow plugs are preheating the engine for cold start on the 516 Vario. | Wait for the light to turn off before starting the engine. |

Most Important Warning Lights
Master Warning (Stop)
Common causes
- Engine overheat
- Hydraulic system failure
- Transmission fault
What to do
Immediately stop the tractor, shut down the engine, and contact your Fendt dealer for diagnostic support. Do not restart until the issue is resolved.
Engine Oil Pressure
Common causes
- Low oil level
- Oil pump malfunction
- Clogged oil filter
What to do
Stop the engine right away and check the oil level with the dipstick. If level is fine, do not run the engine; have it towed to a service center.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Allow the engine to cool, then check and refill coolant. Inspect the radiator for debris. If overheating recurs, consult a technician.
Transmission Temp
Common causes
- Overloading the Vario transmission
- Low transmission oil
- Cooler malfunction
What to do
Reduce load immediately to allow transmission to cool. Check oil level and condition; if hot, let idle until temperature drops before resuming work.
Brake System
Common causes
- Low brake fluid
- Brake pad wear
- Hydraulic leak
What to do
Check brake fluid reservoir; if low, top up and inspect for leaks. Avoid driving the tractor and have the brakes serviced.
Frequently Asked Questions
What does a flashing check engine light mean on my Fendt 516 Vario?
A flashing check engine light indicates a severe misfire or catalytic converter damage risk. Reduce load immediately and have the tractor diagnosed by a technician.
How do I start a parked regeneration for the DPF on the 516 Vario?
Ensure the tractor is parked on level ground, engine at operating temperature, and PTO/implement disengaged. From the display menu, select 'DPF Regeneration' and follow prompts.
Why is my transmission temperature light coming on during heavy tillage?
Heavy loads can overheat the Vario transmission oil. Reduce ground speed or shift to a lower gear. Also check that the transmission oil cooler is clean.
Can I clear the master caution light myself?
The caution light may reset after fixing the cause and cycling the ignition, but persistent faults require dealer diagnosis. Consult your operator's manual for fault codes.
What should I do if the AdBlue indicator stays on after refilling?
The system may need a few minutes to register the new level. If it stays on, there might be a quality issue or sensor fault. Drive the tractor; if light persists, visit your dealer.
How do I check the hydraulic oil level on the 516 Vario?
Park on level ground with implements lowered. The reservoir is located behind the cab; check the sight glass or dipstick when oil is warm. Top up with Fendt-approved hydraulic fluid.
