2013 GTI SE... Just got a brand new EZ port 2i jet ski port. Drove the ski up on the port for the first time today and when I backed off and started engine I got an IBR error message. When I checked the fault codes I found p1661 and c2102. Would turn the ski on and off a couple of times and eventually the fault would clear and the ski would operate as normal. Just a coincidence that I had this problem the on the first launch off the port? What are the possible causes of this problem and should it be an easy fix?
