Amaze AdBlue System Failure

I have a 2023 Honda Amaze diesel with about 68892 km. The AdBlue tank seems empty after a refill. The speedometer shows an error, and a scan says there's an SCR catalyst system error. Now the engine won't start. Could this be a bad AdBlue output from the tank to the dosing unit? Any ideas about the tank capacity or what might cause this?

Summary of the thread

A 2023 Honda Amaze diesel owner experienced an AdBlue system failure, indicated by an empty tank after refill, a speedometer error, and an SCR catalyst system error, leading to the engine not starting. The issue might be due to a faulty AdBlue output from the tank to the dosing unit or a malfunctioning pump not drawing DEF fluid. Suggestions included checking the connections to the dosing unit and inspecting the SCR catalyst for damage. Ultimately, the problem was identified as a faulty AdBlue pump, which required professional repair.

I also drive a Honda Amaze and had a similar problem recently. The error message and the engine not starting made me think of the AdBlue system. I'm not an expert, but check the connections to the dosing unit first. Is AdBlue fluid actually being drawn from the tank? Maybe the pump isn't pulling the DEF fluid. Also, check the SCR catalyst for damage.

Thanks, I appreciate the advice about the dosing unit and pump connections. How can I check if AdBlue fluid is being drawn from the tank? What should I look for? I'm not familiar with diesel exhaust systems, so specific guidance would help.

The garage confirmed my pump wasn't drawing fluid. You might see a blockage visually, but it's hard to know without special tools. Given your symptoms, mileage, and the engine not starting, I'd suggest a workshop that can diagnose SCR catalyst issues. It could save time and damage. I had the same issue and had to get it professionally checked after some basic checks.

I understand. Thanks for sharing your experience and recommending a workshop. I'll book an appointment to have the AdBlue system inspected. It turned out to be the AdBlue pump, and the repair was about 250€. Thanks again!
