Hello Did not pass the AU test at the TÜV, since it does not bring exhaust gas values. Stinks however after unburnt fuel. I changed spark plugs, Lamda probe is new, Zünkabel in order, Kat new, rest of the exhaust gas new, blows a little bit, but that can not be. Who can give me advice, what or where you can still look for, dealer are also almost all changed. I have almost 278 T`km on the engine, but he needs almost no oil and is also very economical in consumption, what could it may be, can one of you help me?
