I bought a Yeti 5L 2.0 TDI with 233,000 km. Now the indicator light for the DPF has been lit for a short time. I have now driven five tank fillings with Mathy DPF cleaner. Now the indicator light lights up again. If someone has experience what a burn out by a specialist company costs, or needs a new DPF. I would be grateful for a cost experience for this too.
