Hi, I recently had my Yeti 1.2tsi DSG serviced and the cam belt changed, as advised at 5 years. Since, the car sometimes judders at low revs, as if about to stall. A factor seems to be that the car is in too high a gear, ie changes up too soon and holds it for longer (e.g. 4th at 20mph). I’ve sometimes addressed this by moving into manual and dropping a gear. I’ve had a situation where I couldn’t get acceleration, I suspect because the revs were held too low for the turbo to engage. Put simply it’s as if the ‘intuitive’ link between the engine and transmission is less effective. I also occasionally notice the engine miss a beat at idle. Prior to the service the drive was very smooth, and DSG gear changes almost always imperceptible and appropriate.
The garage is aware, and I’m taking it back to give them a chance to fix it, but I’d value people’s suggestions for possible causes and solutions so I’m prepared. Please note my mechanical knowledge is slight! Thanks very much.
