On the verge of turbo failure... and maybe worse
A dirty Fap on a Scania G410, and no power at all
We worked on this Scania G410 6-cylinder DC13115 engine, i.e. the 410hp 13L which also develops 2150Nm of torque. First of all, we went through the case to find out what faults were present. The result was a clogged DPFS. When we started up the truck, we realized that it wasn't even revving any more, and that we couldn't feel the exhaust gases escaping. We advised our customer not to drive the vehicle in this condition.
What are the consequences of this?
- Power loss: When the DPFS is clogged, exhaust pressure rises, resulting in a loss of power and reduced engine performance. (degraded mode).
- Turbo damage: The turbo is powered by exhaust pressure. If this pressure is obstructed by a clogged DPF, it can damage the turbo's bearings, leading to oil leaks and even breakage of the turbo's fins, which can then pass into the intake and into the engine.
- Increased fuel consumption: If the engine has to work harder to overcome the restriction caused by a clogged DPFS, fuel consumption rises.
- Starting problems: When the FAP is too clogged in cases like this, it limits the amount of air reaching the engine, which can cause starting difficulties or even prevent the engine from starting at all. There's also a risk of turbo failure due to over-pressurization.
How to get rid of a clogged DPFS for good?
The first thing to consider is the type of work performed with the vehicle. In our case, a lot of static PTO work, which is problematic for regenerations. The ultimate solution (especially if you're planning to export your vehicle) is to completely remove the regeneration and AdBlue injection systems.
The 2016 Scania G410 is equipped with an EMS S8 ECU. It uses the Can Bus to communicate with the EEC3 unit, which monitors emissions. Reprogramming the EMS S8 engine ECU therefore eliminates any information feedback between the EMS and the EEC. The operation is performed by flashing the EMS memory.
It is imperative to dismantle and remove the dirty DPF cartridge on Scania G410 after our intervention to restore the vehicle's efficiency. Otherwise, the risk of turbo failure, and perhaps worse, engine failure, is always present.
Maximizing the performance of your G410 DC13 115
Understand that the 410hp Scania DC13 115 has engine components borrowed from the 450, such as turbo, injectors, HP pump, and a GRS905 gearbox similar to that of the 450. However, the only difference is in the clutch, which is why we can't increase torque values to those of a reprogrammed 450. However, this still translates into a significant difference in terms of power and driveability. Power rises from 410hp to 490/500hp, and engine torque increases by 250Nm. The gain is also felt when using the PTO.
