Today, I might have sadly initiated an end of the journey for my A2 1.4 TDi. If the fallen object is found then no issues, if not
While trying to change Intercooler air sensor, a screw head came off and has dropped in the oil filler tube not to be found anywhere in the vicinity. I checked and it's not fallen on the under tray. Fortunately having realised immediately, I haven't started the car and it has been towed to the nearest Audi specialist. Lets see what happens in upcoming days.
The hope is that it will still be logged in the horizontal part of the filler tube. If not has fallen down in the sump and it can be retrieved by removing the sump. I will highly appreciate some knowledge from the members on the forum.
Fingers crossed.
