Hey guys. I bought a 2008 K12 cdi from someone that I trusted however found much more faulty with the lovely little car than told about. The latest problem has the most experienced diesel mechanics baffled. The engine cuts off after about 1 and a half minutes. Restart no problem, then again cuts out and so on. Every 1 and a half minutes. The only fault (that is left from the 10 initially) is a 'rail pressure' I think they said. Does anyone know what could be causing this? It really seems like an electrical issue somewhere. Please help!!
