Frequently asked questions
Why does my DEF system fault in cold weather?
DEF freezes below about 12 degrees, so the system uses heaters and heated lines. A failed heater sets a fault and can start a no-start countdown.
What is the no-start countdown?
Emissions rules make the van count down starts when a DEF fault is unresolved. We fix the heater or line and reset the countdown before it reaches zero.
Is it the line or the tank heater?
We test the heater circuit with Xentry to see whether the heated supply line or the in-tank heater failed, so we replace only the part at fault.
Can I still drive with a DEF heater fault?
For a while, but the countdown will eventually prevent restart. It is best to address it before a cold snap leaves you stranded.
