The owner of a VW Passat B6 2.0 TDI CBBB 170 hp contacted us for a DSG6 DQ250 transmission reprogramming. The owner was dissatisfied with the transmission’s performance. It was experiencing low-revving, sluggish operation, vibration, and excessive load on the flywheel and clutch. Everything was done for environmental reasons, not driver comfort. We optimized the transmission. After the reprogramming, the car now responds more predictably to throttle inputs, the unpleasant vibration disappeared, and driving around town became comfortable.
