2011 VW Jetta TDI: Second Guessing
April 20, 2011
See that flowchart above? That's what it's like when you apply pressure to the accelerator. Whether it's throttle tip in or turbo lag, I don't know, but I don't like it. Our new diesel Jetta just seems hesitant to comply for the better part of a second when I ask for a little more power. I don't seem to remember this in our last TDI. Is it something to do with a break-in period? Does the system need to learn our driving style like our Cruze? At least from the driver's seat, it feels like the throttle linkage is made up of about 20 rubber bands strung together. Initially nothing happens, then once there's enough pressure, the engine surges with power. I really hope this isn't permanent.
