My V70-II-D5, 163PS+Chip, year 02/2002, 175Tkm, has recently the following Macke: From the normal ride no more power comes out of the acceleration. Max. top speed is then 125km/h with fully penetrated accelerator pedal & the speed does not come over 2500/min. Sometimes the “sleep ride” goes from even after 10 minutes to 1 hour (does fun during holiday trips) again and then is rest for a few days or weeks until it occurs again. Yesterday I stopped then u and the engine turned off, after the restart everything was OK again. Does anyone know what it might be about?
