2012 r56s hesitates on startup if it's sat for more then a few hours. Doesn't do it every time. 47k on car. Ran the codes with dashcommand and a kiwi2. any ideas? Thanks for your help

 

That would be a pretty good guess , show a gauge for and watch fuel rail pressure next cold start with dash command. Fuel rail should show 800+psi at idle , while mine was having trouble it wouldnt build more than 100psi on cold starts

 

Definitely sounds like that might be your issue. You can check the high pressure system on turbocharged models using a MINI scan tool. We go over this in our tech article if you want to test it. It's under MINI > Tech Info (tab at top) > R56 articles and then scroll down to Fuel Injection and it's the 2nd to last one in that section. Look at figure 10 in the article for specifics. If you determine this is your issue, I have seen N18 owners get theirs replaced under Service Bulletin # 010116. May be worth calling your dealer and checking in on it.
