ECU Tuning solution for Skoda Octavia MKII

For the Skoda Octavia MKll, both DPF and EGR can be removed through ECU software (file). The procedure is explained below.

Skoda Octavia EGR removal solution

1. Use a scanner or diagnosis tool and make a list of EGR related fault codes.
2. Read the ECU using OBD or Bench/Boot.
3. Upload the file.
4. After receiving the file, write it using the same protocol you read the file.

Note: You must disconnect the EGR actuator plug before writing the modified file.

Skoda Octavia DPF removal solution

1. Use a scanner or diagnosis tool and make a list of DPF related fault codes.
2. Read the ECU using OBD or Bench/Boot.
3. Upload the file.
4. After receiving the file, write it using the same protocol you read the file.
5. After writing the file, clear fault codes and do a forced regeneration.

Note: Before writing the modified file, you must disconnect DPF temperature and pressure sensors.

 

Location of sensors in Skoda Octavia MKII

• EGR valve and actuator plug location

The electrical plug is attached to the side of the actuator motor, which is on the left-hand end of the EGR housing (when viewed from the front of the car)

The EGR valve is located on the front side of the engine, near the intake manifold.

• DPF Temperature and pressure sensors

On Volkswagen-group 2.0 TDI CR engines this sensor is commonly known as G450 (“Exhaust Pressure Sensor 1”). 

Location: Mounted on a bracket near the rear of the engine bay, often on the top of the engine block or attached to the engine bulkhead. Look for a small electronic sensor with two small rubber hoses attached; one hose from upstream of DPF, another from downstream (to measure pressure differential). 

Connector: A small multi-pin electrical plug typically attached to the sensor.

Hose routing: One hose goes to the manifold/turbo side before the DPF, the other goes to the after the DPF. This allows the sensor/ECU to measure the pressure drop across the DPF (higher drop = more soot/clogging). 

There are usually multiple EGT sensors on these diesel systems; for your engine you should locate at least:

Upstream EGT sensor (before DPF) - monitors exhaust temp entering DPF.

Downstream EGT sensor (after DPF) - monitors exhaust temp exiting DPF.

These sensors help the ECU decide when regeneration is safe, monitor for over-temp, and detect DPF/DPF bypass issues.

The upstream sensor is typically threaded into the exhaust manifold or the turbo-outlet pipe, mounted high and accessible from the engine bay side.

The downstream sensor is often mounted on or near the DPF body or the pipe after the DPF; sometimes you’ll need to access it from under the car or remove under-body shields.

Connector: Each is an electrical plug, usually under heat shield or protective cover.

These sensors may be labelled in VW/Skoda docs as G235, G448, G495 depending on exact engine.
