Moin, occasionally our Mini Cooper R56 with the 120 HP engine is nailing at the cold start in the morning. Chain tensioner costs not 25€ and I wanted to change it. Especially with the Turbo there seems to be a lot of problems. I have found instructions so far only for the Turbo. Did today the air filter system with ours down and the hoses. I see the 27er screw. Only I can get no nut on it, let alone the one turned out. The throttle valve is in the way. If yes, what to consider when dismantling? Are these only the 2 Torx screws? Please short info. Thank you
