Hello now my V50 has been driving since 2006 and was actually very satisfied.The good has now 232,000 on the hump – the RPF has never been changed! For some time (about 9 months) I notice the following problem: Turbo hole at approx. 2200 rpm – partly no trajectory i.e. it attracts to then hole and attracts again. This error occurs in very small interval at the acceleration – My friend (Volvo contract workshop) is overwhelmed with the problem – reading the error protocol does not bring any result to me it only bothers – now it happens even more often that the emergency system starts – i.e. at 2000upm it completely closes – lastly this happened during the overtaking process – since one can really only curse absolutely inexplicable that the friendly ones find nothing! Turbo should be in order – that can actually only be an electronic problem …?
