As enthusiast, we always come up with solutions to a problem. Breaking parts eventually paved way for a solution and that is upgrading the weak DSG7 DQ200 to a DSG6 DQ250, which has much better torque handling even on a stage3 IS38 setup . Below are the parts we found and made it to work :-
It includes: A gearbox assy (from gen3/mqb platform Golf7 diesel), starter motor, flywheel, driveshafts, and gear selector.
Full DSG recalibration
Being a frankenstein, the parts came from two different cars. The mechatronic unit from one, the gearbox from another. To make this work, we combined a used mechatronic unit, a used gearbox and wiring harness required to connect it to the car. The mechatronic unit did not originate from this gearbox and the gearbox itself from a diesel car, therefore it had to be adapted for use with gasoline. The problem with the mechatronic was it had diesel calibration data, but we now have a gasoline engine. Shift points, gear shifts, rev limiters were all made for diesel. As a result, we completely changed the DSG calibration to match the new engine and hardware parts in the gearbox.
Result? Everything worked perfectly fine as if it was factory fitted. Happy days 🙂
