New Holland T4.90, T4.100, T4.110, and T4.120 Tractor: DEF, DPF, and EGR Delete: Unlock the Full Potential of Your New Holland T4 Tractors
April 2, 2024If you operate a Volvo truck powered by modern emissions-controlled engines, you’ve likely experienced issues with DEF, DPF, or EGR systems. These components are designed to meet strict environmental regulations, but they also introduce common problems such as downtime, derates, reduced power, higher fuel usage, and expensive repair bills.
At TM AG Tuning, we specialize in Volvo Truck DEF Delete, DPF Delete, and EGR Delete solutions that restore reliability, improve performance, and eliminate emissions-related derates once and for all. We tune Volvo trucks across North America every day, offering a premium, proven service trusted by fleet owners and independent operators.
We make the process simple: we provide a UPS shipping label, and you send us your ECU and ACM. Once received, our team performs a full custom delete tune. Horsepower upgrades are included if desired.
What Is the DEF, DPF & EGR System on Volvo Trucks?
Volvo’s emissions systems include three main components: DEF, DPF, and EGR. Understanding how they work—and why they fail—is key to understanding why many operators choose to delete them.
1. DEF (Diesel Exhaust Fluid) System
The DEF system injects urea into the exhaust stream to reduce NOx emissions. It requires:
-
DEF fluid
-
A DEF pump
-
Sensors & heaters
-
DEF injector
-
SCR (Selective Catalytic Reduction)
Common DEF issues on Volvo trucks:
-
Heater failures
-
Crystallized DEF lines
-
Faulty NOx sensors
-
DEF pump failure
-
SCR catalyst efficiency codes
-
Derates limiting the truck to 5 mph
Even small DEF problems can immobilize a truck, costing thousands in downtime.
2. DPF (Diesel Particulate Filter) System
The DPF traps soot in the filter and periodically burns it off during a regeneration cycle.
Common Volvo DPF problems:
-
Constant regens
-
Soot buildup
-
Failed pressure sensors
-
Cracked DPF filters
-
High exhaust temps
-
Turbo wear from backpressure
DPF system repairs often start at $2,000–$6,000+ and can recur repeatedly.
3. EGR (Exhaust Gas Recirculation) System
The EGR system recirculates exhaust back into the intake, reducing NOx but increasing soot.
Common EGR problems:
-
Valve sticking
-
EGR cooler failures
-
Soot contamination
-
Clogged intake manifold
-
Reduced fuel economy
Each of these systems adds complexity, cost, and downtime.
