Hello Elche, after I have recently easily exceeded the 100,000 km, now the following problem occurs at irregular intervals. I accelerate evenly in the fourth or fifth gear, then at approx. 2,300 revolutions the speed falls jerky by approx. 200 – 300 revolutions, after which the acceleration continues normally. The problem does not occur in the first three gears. It only occurs occasionally, sometimes not a whole day. I was at, this has no error My XC 60 (07/2010) will soon be able to go to the , so that he can approach the error. Has anyone ever had something similar, which might limit the error? I have also recorded the phenomenon on mobile phone, which I will send to the sender tomorrow. Ratlose Grüße aus dem flachen Norddeutschland
