Hello colleagues, I have a problem with a Volkswagen Caddy 2004 year 1.9tdi 105hp The problem is as follows, when we start the engine, the red oil light starts flashing and the tachometer on the dashboard does not work.DTC is 18058-Powertrain Data Bus P1650 Missing Message From Instrument Cluster.Two cable(Can Low and Can Hight from ECU to the instrument cluster have been replaced with new cables.Tried another instrument cluster from the same car, another gateway and another ЕCU.I am asking only for competent opinions, such as check the oil pressure and the like, I will ask that they be spared ,Thanks
