I've looked and read almost everything i could find on N63 problems and CCP but couldn't find a good answer on whether CCP fixed the problem or not. I want to upgrade my 2011 335d to a V8, x5 or x6. Some people here stated that their 2013 x5 had n63tu others said they were looking to buy a 2013 x5 and dealer claimed it had n63tu. This is a bit confusing bc CCP covers n63 up to 2013. Can somebody clear this confusion?
