moin,moin sufferers and colleagues… I would need your advice and suggestions about what I could do. short description: audi 80 cabrio, 2.3, 187 tkm consumed in the city with really normal driving almost 15 liters on 100 km. I find that too much! what I have to say is that the “snorkel” was removed from the air filter box over to the bender. why can you think for sure…SOUND ! can the more consumption be related to it? and what can I do? n, or check for defective ones, what could explain the consumption? the days will renew the ignition plugs, the air filter and the distribution cap….. so, especially the young ones among you with real idea, please write a few tips….always many thanks…
