Frequently Asked Questions
Why does my Steyr 6150 CVT show a red master warning when I start it in cold weather?
If the engine oil is too thick or battery voltage is low, the master warning may appear. Ensure battery is fully charged and use engine block heater if below -10°C. The light should go out after a few seconds if no actual fault exists.
How do I reset the service light on the Steyr 6150 CVT?
The service light is reset automatically after the scheduled maintenance is performed and the interval is reset via the diagnostic menu. Access through the right-hand control panel: press and hold the 'Menu' button until 'Service Reset' appears.
What does the blue work light indicator mean if it's flashing?
A flashing blue work light indicator indicates a fault in the lighting circuit, such as a burned-out bulb or a loose connection. Check the rear and front work light bulbs and replace any that are failed.
Can I continue operating my Steyr 6150 CVT with the amber transmission temp light on?
It is not recommended. Reduce load immediately. If the light goes out after a few minutes, you may continue at reduced power. If it stays on, stop the tractor and allow the CVT to cool. Extended operation may cause transmission damage.
Why does the DPF regeneration light come on during light field work?
Light load operations don't generate enough exhaust heat for passive regeneration. The ECU initiates active regeneration to burn accumulated soot. If possible, increase engine load (e.g., raise the implement) to assist the process.
How do I check the transmission oil level on the Steyr 6150 CVT?
Park on level ground with the engine off. Locate the dipstick on the left side of the transmission housing. Remove, wipe, reinsert fully, then check the level. Top up only with Steyr CVT fluid through the filler port.
