Hello together My girlfriend has a Mini Cooper, built in 10/2006 R56 1.6 as first owner. So far the car ran without problems and was always with BMW to customer service. For about 600 km the MKL lights up and as error stands 0x283D VANOS outlet: adaption stop in the error memory. Can sometimes be deleted and either comes back immediately or it takes about 2-3 days. Camshaft sensor has been renewed and cross-changed. BMW excludes the control chain. Recently the valve cover seal has been renewed and there they meant the chain looks good. Sit tight. Have taken off the valve cover and looked at it. Looks really good. Chain tensioner is relatively new. What else could it have on it? BMW offers a fault search but says in advance that it can go in the 4 digit range. Does my girlfriend want to avoid that. Can it possibly be the control chain or maybe the control times no longer agree and you just have to adjust them again? Many thanks for your support.
