HALLO!! Have a big problem and need urgent help!! Have an Audi 80 Bj.91; 1.8 gasoline automatic! Mileage 92.000km! Have always cared for the car and kept it waiting! But suddenly 3 days ago on the highway the brake amplifier hose and the hose burst from the air filter to the engine! This I messled by my car only time-wise took my gas! I changed the hoses myself and drove to the workshop because I heard funny engine noise! On the way there I had to drive backwards at the driveway to r Werkstat with full steering to the left and the car went off! During rolling!! In the workshop I was told that the 1 & 3 cylinder did not get enough compression! The first even only three bar! Reperature costs over 1000€!! I could not believe this because the car has a few kilometers and always drove problemlessly!!! Another mechanic said that it was due to the spark plugs! Can jmd. help further??? I would be very grateful!! THANK YOU! !!
