Frequently asked questions
What is an SCR efficiency code?
It means the catalyst is not converting enough NOx. Causes include crystallized DEF, a bad injector or mixer, or a worn catalyst. We test conversion with Xentry.
Can crystallized DEF be cleaned out?
Sometimes. If deposits are the issue and the catalyst is sound, we clean them and check the injector. A degraded catalyst is replaced.
Why did the SCR catalyst fail?
Contaminated DEF, a leaking injector, or high miles can foul or degrade it. We check the whole SCR circuit so a new catalyst is not fouled again.
Will this clear my no-start countdown?
Repairing the SCR fault and verifying conversion clears the code and the countdown. We confirm readiness with Xentry before you leave.
