DPF and Custom Remap Package on an Audi A5 3.0TDi
In the workshop last week for a dpf delete, egr valve blank and custom remap an 3.0 Audi A5 tdi Quattro. After talking to his friend who had already experienced the package deal, our customer booked in to get the same done to his car.
With the DPF carefully removed from the engine bay, we began the process of removing the DPF filter from the casing. With the DPF filter removed from the casing we welded it back up and refit the casing back into the engine bay. Next we fabricated a blanking plate to blank the EGR valve. With the engine bay built fully back up it was time to reprogram the ecu to prevent the car from regenerating before we headed over to the 4wd rolling road.
With the Audi A5 being a true Quattro we where unable to remap the car on our 2wd rolling road so we headed over to a 4wd we have access to. With the car strapped down to the rolling road the process of reading the ecu files began. Once we have read the file we can begin to write our own file to suit the modifications. As we write the remap the car is run on the rolling road so we can monitor the fuelling etc. Once we are happy with the results of the remap we do a final few runs to see a true reflection of the power.
With the dpf package deal completed it was time for the customer to test drive the car. Having already been out in his pals Audi A5 as a passenger he thought he had an idea of what the drive would be like. How wrong could he be 😉 When he returned from the test drive he said he was amazed by how responsive the car was and how the power just kept on coming. We had not only just improved the performance but the customer will also see an improvement in fuel economy AND he had gained 3 more bhp than his pals car 🙂
