Re: Stuck On 3rd Gear
One thing I found with some research is that U codes are Network issues on the CAN-BUS. As an IT person, this means some sensor or module is having a problem. There's nothing out on GOOG that explains what this may be so it may require a dealer visit to sort out.
hope that helps.
