Hello, I urgently need the part number for the vertebra of our V50D5 Bj2007/Mj2007 (before the facelift!). If needed: vehicle ID: YV1MW774962228884 engine: D5244T8 vertebrae valve is allegedly defective, or the rod hangs out again and again and Fzg regulates then from approx. 160 to 170 km/h on the highway again, at the same time yellow engine warning, speed goes down then up to approx. 130-140, then he takes again gas and the game starts from the front. Our friend has already 2 times provisional the ‘stack again’, at least he said so. But now have it enough with the engine warning (even with the researcher giving gas in the city) and want to exchange the defective thing. Maybe someone has the part number of the part that I need or really means vertebrae? And how much does it cost me? Do I only war that with Volvo or elsewhere? Many thanks anyway for your effort for your part number, which I really need?
