Moin people… my CFFB has now 210t km down, has hot start problems here and there, sounds like misignition with throw off. During the ride I had already read out the injection rate correction values, which go down partly with the cylinder 1 to -2mg/hub while the other counters, but above all under load. In the low speed range twitches and jerks it. Yesterday I measured the total return rate, 50ml in 1 minute. According to Erwin 0-50ml per 2 minutes ok… The rail pressure calibration points are all in the minus, the days would possibly test the injectors individually for the return rate. Would you exchange only one or better all? Does anyone have experience with diesel technology Biberach with overhauled injectors? Me were offered 4 for 48€ in exchange… Injection rate deviation:https://www.skodacommunity.de/attachments/1674905148682-png.226708/
