I have looked back through the old threads and I cannot find anything relevant to my issue. Sometimes when I start my 2019 RS3 first thing, my turbo boost gauge shows full boost on idle. When you drive off, and accelerate the gauge goes down, stop again and it shows full boost again, now these keeps happening for a few miles and then back to normal Operation. I have looked through the handbook and cannot find any reference to this, so is it dealer contact time. Thanks in advance for any advice.
