He broke the exhaust gas test with the statement ,that probably the lamda probe is not in order , the mixture is too fat ! Since I am unfortunately already a bit older ,( shortly before 68 ) I do not know with the removal , or installation ! Is my first Omega with this technique ! How about these parts , from the bay from ? Foh preiß original 225,00 replica , also from the Foh 115 in the bay 40,00 Euronen !! How can I get out the Lamda sonde best in self help ?? What must I notice ??
