Hello together, we drive a Yeti 2.0 TDI, 81 kw, year 2011 with meanwhile about 84tkm. We bought it at the time 03/12 with about 14tkm and are mostly satisfied with the vehicle. Up to the time, at which the phenomenon occurred that about every 2-300 km the “DPF symbol” lights up in the instrument cluster and you have to drive the DPF “free”. The problem started about early 2017 (but still at higher intervals) and so massive it occurred since the software update of the engine STG at the friend In the end, the AGR valve was replaced completely in June 17. The problem with the AGR valve was fixed at least once. However, the short intervals with the DPF regeneration remained. Our driving profile is (in the meantime) 95% short distance in the place – I know, not really optimal. Diagnostic cables and VCDS are available. In the real-time log you can use normal driving times. see how the “mass of soot calculated” increases by 0.01 g in a second. Until it becomes too much at about ~40 g at some point and the DPF has to be regenerated. The ash loading is allegedly at 0.00 l (?!?). What possibilities do I have to test different components using VCDS to get to the problem if necessary? What I notice in comparison to “earlier” is that the diesel gases smell “bice – russ”. Maybe someone can help me before I can un- I’m sorry, but I don’t have any confidence in this anymore. Thank you very much.
