Hello Elk friends, a few days ago our Volvo had a couple of jerks at approx. 2000U/min and with strong acceleration. Is of course very disturbing – could get worse. I have pondered a bit and came to the assumption that this might be due to water in the fuel filter. After all, it was not drained about 50,000km (yes, a new filter already due). So, now to my question: Does the system have to be vented after draining?? It’s the 1.6l TDI, D4162T, in a V70 III
