I’ve had a problem with my C3 2.0D DPF since yesterday (2008). When accelerating from lower speeds, there is a lack of perceptible power and it’s particularly striking when accelerating in upper gears on the highway: initially hardly any power, then again full power, again hardly any power, again full power, etc. in the interval of about 1 second. Maximum speed: 180km/h on a straight track. Controlling and reading of the fault memory gave no result. About four months ago, I was also equipped with normal gasoline instead of diesel. Complete injection system, hoses were renewed and tank cleaned. Could this be a consequential damage now? Who can I be held liable for in this case?
