Gearbox change from 5-speed RTH to 6-speed QFZ

Post by kile81 »

As the title says, I swapped the RTH gearbox for a QFZ gearbox in DFSD. I changed the software from 016Mq to 016BT because I couldn't code the 6-speed gearbox. I've encountered significant problems. The car doesn't produce any power. The DPF clogs too quickly, at 0.1 g/min. It doesn't show when I'm in 5th gear. Does anyone have the 04L906016MP FRF file?

Yes it does, just had mine changed rth to O2Q pulls like a train better power delivery, down side had the start stop disabled, dash reads 4th in 4th and 5th reads change to 5th and in 6th reads 5th. This is due to the ecu reading revs to wheels speed moving mines the orig ecu

Hey @kile81
i am also in the process of installing a PDT 6-speed transmission in my DFSD. Unfortunately, my engine control unit also has SW 016MQ installed. Have you made any progress with your conversion, and is it working for you with the 016MP SW?
