Good tomorrow volvo v70 fans…. Here’s my idea, I am a couple of months volvo v70 t5 Bj 2002 owner with mega power 184kw and chipped so nearly 300ps and unfortunately have a problem that I can not solve! Motor jerks from time to time at 2000-3500 revolutions it lit motor light and error was loud friendly cam wave sensor but it has fix nothing because if I am funny the battery hangs off for 10 min it goes again without problems so 50km then it starts again… I suspect a current problem because the light in exactly when jerking off and flickering at slightly…. Can anyone give me a tip? I mean the speed drops strongly up and down. At the stand or at the start never problems like from 3000 revolutions to 6000 also no problems but then switches the automatic then eh… ask for help… Mfg AnDy
