Hey, guys.



I took Grandpa's A8 3 weeks ago and it just doesn't end with the mistakes on the car, Grandpa said to him he always ran without problems.... Ever since I drove him from the first meter, it started.. So until now I have repaired everything else even the alarm system that starts by itself is now going again...

now I have the error here in the memory



16538 - Bank2 probe1 no activity



P0154 - 35-10 - - -sporadic



Lambda probes are ok, what I noticed all candles were really fussed with deposits that were made in February at KD. I bought and installed new candles from Bosch, but the mistake is still there. The blue injection nozzles all have uniform pressure.. I just can't get any further with the search function...



Maybe someone can help me further, it's a 98 A8 2.8 quattro manual transmission.



Thank you

Woher weißt du das die Lambdasonde okay ist?

Lambdasonden beim Wechsel stets nur die Originalen, Beru und Uni zeigen häufig Fehler. Wie hast du sie gemessen? Bei den Messwertblöcken muss die Regelung sehr schnell sein, langsame oder gar keine ändernde Werte zeigen eine defekte Sonde.
