To put it another way, deleting a diesel implies removing some or all of the emissions control equipment. Catalytic converters are the simplest to remove, as all that is required is the installation of a straight pipe in their stead. The process of removing an EGR system is a little more involved, needing blocking plates on the easy end and new exhaust up-pipes on the tough end. The removal of the diesel particulate filter (DPF) or selective catalytic reduction (SCR) system is also simple, requiring only the replacement of the exhaust system. Removing the EGR, DPF, or SCR, on the other hand, necessitates retuning the engine computer to fit the deleted equipment.
Is deleting a diesel illegal?
It’s not difficult to find someone who can modify or remove the Diesel Exhaust Fluid (or DEF) emissions systems on your agricultural equipment if you look hard enough. Given the openness with which this service is provided, a farmer could be forgiven for thinking DEF alterations are permitted.
They aren’t. The EPA Clean Air Act forbids anybody from removing or rendering inoperable an emission control device on a motor vehicle in the United States. Under a different name, the Canadian Environmental Protection Act, Canada has essentially the same statute.
Even though it is forbidden, DEF tampering occurs. What is causing this, and what are the potential consequences?
Early DEF systems, according to Kevin Rossler, Sales Manager for Markusson New Holland Ag in Regina, could be problematic.
“There were early concerns in agricultural equipment as it developed into Tier-Four emissions or DEF systems,” explains Rossler. “An error code from a sensor failing at seeding time could cause you to lose power, which is quite inconvenient. As a result, several operators wanted to get rid of their DEF systems or purchase DEF delete kits to avoid having to utilize them.”
Interfering with a DEF system can get you in trouble with the law, but that’s not the only danger. It will also nullify the manufacturer’s warranty on the equipment. When equipment with tampered DEF arrives at a dealership as a trade-in, it must be returned to its original DEF settings before it can be resold. That’s $5,000 to $7,000, according to Rossler’s experience.
He advises equipment owners to let go of any remaining misconceptions regarding DEF, stating that current versions of the technology work significantly more consistently. DEF systems are unlikely to cause problems in the field, but they’re excellent at what they’re supposed to do: regulate emissions from agricultural equipment and help farming keep its good environmental reputation.
“Early DEF systems are nothing like what we have now,” says Larry Hertz, WEDA’s Regional Vice-President for Canada. “Today, you could place your face right close to the exhaust pipe and nothing would come out. DEF is required by legislation in order to maintain air quality. That’s all the more incentive to leave your DEF alone and let it do its thing.”
How do you tell if a diesel is deleted?
You will be eliminated if your intake horn has a “Blue” plate on it. The factory EGR pipe would be connected there. On the left side of the engine, you’d also have a huge EGR cooler and some cables for a valve; now, you should only have two plates on the exhaust manifold where it would have been.
What are the benefits of deleting a diesel truck?
By recirculating a part of the exhaust back into the engine, the EGR helps to reduce pollution. However, due to the numerous faults with the EGR, many operators choose to have it removed. An EGR delete entails removing the system with a delete kit. Engine performance, fuel economy, and not having to worry about EGR emergency maintenance are just a few of the advantages (or even the engine itself). Because particles, soot, and debris can build up over time when recirculated back through the engine, it may require more maintenance than an engine without an EGR. It’s all a huge part of the value proposition of getting rid of the EGR entirely.
Can a dealership sell a deleted diesel truck?
A dealer is not allowed to sell a deleted automobile under federal law. It’s better to put it back on so they don’t refuse the transaction or value drops by up to $6k because it was removed.
Is deleting a diesel good?
To put it clearly, any diesel pickup’s emissions equipment should not be removed. It is a federal criminal to remove any factory-installed emissions equipment, regardless of local or state testing regulations. The factory warranty on the vehicle is also void when emissions equipment is removed. Before you say anything, there is no way to prevent a dealer from discovering that emissions equipment has been removed. Even if the hard parts are replaced, the ECM will still show signs of adjustment.
How do I know if my DPF has been removed?
The car will fail its MOT if a filter has been removed. When the DPF is removed, the warning light may illuminate, which is a MOT failing point because no dashboard warning lights should remain illuminated during the test.
What does studded and deleted mean on a diesel?
#2 6th of July, 2011. Aftermarket studs that go over the Ford head bolts are known as ARP Head Studs. The term “studded” refers to ARP head studs, whereas “non-studded” indicates that your truck is stock. I tow 11.5k without studding and haven’t had any problems. However, the EGR (Exhaust Gas Return) has been removed.
Is deleting a truck worth it?
Most contemporary trucks come with DEFs as standard equipment. DEF systems function in tandem with the factory SCR (selective catalytic reduction) system to break down and clean up exhaust fumes before they exit the exhaust system. You can save money by deleting your DEF system.
Will a deleted diesel pass emissions?
If you’re erased, you must restore the truck to its original state (exhaust and tuning) in order to pass. If you’re using emissions-compliant tuning, you may need to revert to the stock tune or the tune with the fewest features.
