LandCruiser Washer Fluid Sensor Issue

I had a similar issue with my 2012 Audi A4. The dashboard light was on, but the reservoir was full. In my case, the problem was a faulty washer pump. It was still throwing the "low level" error though the jets weren't spraying anything on the windshield. Have you listened to see if you can hear the washer motor running when you activate the system?

Good point! I haven't actually listened for the motor. Where is the washer motor located on the LandCruiser? And if the motor is running, but nothing is coming out, what else could it be besides the pump?

The washer motor is typically attached to the washer fluid reservoir itself. If you can hear the motor running but the spray jets are not working, the issue may be clogged spray jets or a blockage in the lines. However, given the error code stored in the memory and that the system isn't working, a visit to a workshop may be necessary to pinpoint the exact issue and prevent further damage to the vehicle.

Thanks for the advice! I took it to my local shop, turns out it was a faulty windshield washer pump, just like you thought! A replacement cost me 25€ including installation. Now I can clean my windshield again!
