Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Radiator blockage
  • Fan belt failure

What to do

On Valtra A Series, stop engine, let it cool, then check coolant level and radiator screen for debris. If belt is loose, replace it.

Transmission Overheating

Common causes

  • Excessive load
  • Low transmission oil
  • Clutch slipping

What to do

Reduce travel speed or PTO load. Check transmission oil dipstick (located near rear) and top up if low. If persists, inspect clutch.

DPF Clogging

Common causes

  • Frequent short trips
  • Low exhaust temperature
  • Dirty fuel

What to do

Perform parked regeneration via the A Series dashboard menu. If light remains, dealer may need to force regeneration or replace filter.

Low Engine Oil Pressure

Common causes

  • Low oil level
  • Oil pump failure
  • Worn bearings

What to do

Immediately stop the A Series engine. Check oil level with dipstick; add correct grade (15W-40). If light persists, do not run engine – call dealer.

Battery Not Charging

Common causes

  • Loose alternator belt
  • Blown fuse
  • Faulty alternator

What to do

Inspect belt tension on the A Series; tighten if loose. Check 20A alternator fuse in the fuse box. If belt and fuse okay, alternator likely needs replacement.

Frequently Asked Questions

Why is the DPF regeneration light flashing on my Valtra A?

A flashing DPF light means regeneration is happening automatically while you drive. Just keep working at moderate engine load until the light stops flashing.

How often should I drain the water separator on the A Series?

Check daily (or every 10 hours) especially in humid conditions. Open the drain valve under the fuel filter until clear fuel flows – sediment and water first.

What type of AdBlue does the Valtra A Series use?

Use standard ISO 22241 AdBlue (DEF). The A Series has a 13-liter tank under the cab step; top up when the amber light comes on.

My A Series won't start; the glow plug light stays on. What's wrong?

If the glow plug light stays on continuously, there may be a fault in the preheat system. Try cycling the key off and waiting a few seconds; if it persists, check the glow plug relay fuse (30A) under the dashboard.

What does the amber differential lock light mean if it stays on?

It indicates the diff lock is engaged. On the A Series, disengage by pressing the button again or by turning the steering wheel slightly to release pressure. If it stays on, check the microswitch or solenoid.

Can I clear the service hour meter myself on the Valtra A?

No, the service interval reset requires dealer software. However, you can view remaining hours on the display. Follow the recommended 500-hour oil and filter change schedule.
